Source : VW emissions scandal: fixes announced for EA189 diesel engines

Volkswagen details the technical fixes the item will use to bring two of its EA189 diesel engines into line with current emissions legislation


Volkswagen Group has detailed the technical fixes which will be used to bring two of its EA189 diesel engines into line with current emissions standards.

The fixes, which are for the 1.6-litre as well as 2.0-litre diesel engines, have been presented to the KBA authority in Germany to be ratified before being offered to the public. Volkswagen says the fixes rectify emissions on “the majority” of vehicles affected by the ongoing emissions scandal. In a statement, Volkswagen says “after implementation of the technical measures, the vehicles will comply with the applicable emissions standards.”

Detailing the measures which will be taken to remove the ‘defeat device’ software via its engines, Volkswagen revealed the following information.

EA189 1.6-litre diesel engine – VW says a completely new ‘flow transformer’, a mesh used to calm air flow around the air mass sensor, will be fitted. The sensor can be used to measure air mass throughput, as well as helps to regulate the internal combustion process. In addition, a software update will be applied. In all, the fix should take less than one hour.

EA189 2.0-litre diesel engine – These engines will only receive a software update, which should take less than half an hour.

“Thanks to advances in engine development as well as increased simulation of currents inside complex air intake systems, in combination with software optimisation geared towards This specific, the item has been possible to produce a relatively simple as well as customer-friendly measure,” reads VW’s statement.

“The objective for the development of the technical measures can be still to achieve the applicable emission targets in each case without any adverse effects on the engine output, fuel consumption as well as performance. However, as all design variants first have to be measured, the achievement of these targets cannot yet be finally confirmed.”

The technical solution for the 1.2-litre EA189 engine will be presented to the KBA at the end of This specific month, VW said. The company also said its sister brands, Audi, Seat, Skoda as well as VW Commerical Vehicles, were also planning their own corresponding measures to fix affected vehicles

VW admits 3.0-litre engines are affected

Earlier This specific month, VW admitted that will its 3.0-litre diesel engines are also affected by the widening emissions scandal – potentially affecting another 85,000 vehicles.

Officials via Volkswagen as well as Audi admitted to the US Environmental Protection Agency last week that will vehicles with those engines also contained ‘auxiliary emissions control equipment’ that will was not reported to the US authorities. the item can be understood that will This specific latest admission affects cars via the 2009-2016 design years.

A Volkswagen spokesperson confirmed to Autocar that will This specific latest revelation only affects cars inside US, as well as refers to an auxiliary emissions control device that will warms the catalyst via cold. The device can be designed to reduce emissions as well as protect the engine during colder starts. The spokesperson said that will the allegation of more cheating has surfaced because VW didn’t declare the device during the vehicle homologation process. the item’s understood that will the device has been declared illegal because the item wasn’t registered as part of the test.

The EPA had alleged earlier This specific month that will VW’s 3.0-litre V6 engine was also cheating in emissions tests, something the company had initially denied. The EPA says that will NOx emissions on the affected vehicles are up to nine times legal limits. the item has identified the VW TouaregPorsche Cayenne as well as Audi A6Audi A7Audi A8, Audi A8L as well as Audi Q5 as being potentially affected.

Speaking to Reuters, Audi spokesman Brad Stertz said that will while the auxiliary emissions control software can be ‘legal’ in Europe, Audi did not “properly notify regulators” of the device.

Sterz said: “We are willing to take another crack at reprogramming to a degree that will the regulators deem acceptable.” He also said that will the cost of rectifying the software might be inside “double digits millions of euros.”

Cynthia Giles, assistant administrator for the Office for EPA’s Enforcement as well as Compliance Assurance, said: “VW has Yet again failed its obligation to comply with the law that will protects clean air for all Americans.

“All companies should be playing by the same rules. EPA, with our state, as well as federal partners, will continue to investigate these serious matters, to secure the benefits of the Clean Air Act, ensure a level playing field for responsible businesses, as well as to ensure consumers get the environmental performance they expect.”

The EPA documentation alleges that will the affected cars have “software inside electronic control module of these vehicles that will senses when the vehicle can be being tested for compliance with EPA emissions standards. When the vehicle senses that will the item can be undergoing a federal emissions test procedure, the item operates in a low NOx ‘temperature conditioning’ mode. Under that will mode, the vehicle meets emission standards.

“At exactly one second after the completion of the initial phases of the standard test procedure, the vehicle immediately modifications quite a few operating parameters that will increase NOx emissions as well as indicates inside software that will the item can be transitioning to ‘normal mode’ where emissions of NOx increase up to nine times the EPA standard, depending on the vehicle as well as type of driving conditions,” said an EPA statement.

“In some other tests where the vehicle does not experience driving conditions similar to the start of the federal test procedure, the emissions are higher via the start, consistent with ‘normal mode.’”

VW executives could face jail sentences

Executives inside UK could be imprisoned for up to 10 years for their part inside emissions scandal, secretary of state for transport Patrick McLoughlin has revealed.

Responding to enquiries via Louise Ellman MP, who chairs the Commons’ Transport Committee, McLoughlin revealed that will the department for transport (DfT) could prosecute VW for providing “materially false” type approval information under the Road Vehicles (Approval) Regulations 2009 – an offence that will can be liable for an unlimited fine.

He added that will the Competition as well as Markets Authority could launch action under the Consumer Protection via Unfair Trading Regulations 2008 for unfair commercial practices, leaving VW liable for an unlimited fine or two years’ imprisonment, or both.

Finally, he added that will the Serious Fraud Office may prosecute VW for doing a gain via false representations, an offence under the Fraud Act 2006. This specific subject to a maximum 10 years’ imprisonment, an unlimited fine, or both.

inside wide-ranging letter, McLoughlin also confirmed that will every some other a new type approved inside UK had currently written to him confirming they have not been involved in any cheating of the testing system, as well as he made the item clear that will the government’s primary focus was to ensure that will buyers of affected cars were not materially affected. As such, he reported he had sought reassurances via VW that will cars might be fixed without affecting performance by the end of 2016, as well as made the item clear that will VW might be liable for any backdated fines.

McLoughlin added that will there are “no specific plans” to change MOT emission tests at the present time, however he admitted that will he may use the tests to monitor whether owners of affected vehicles contain the fixes put in place.

the item has since been confirmed that will fixes for the EA189 2.0-litre engine will be approved in January/February next year before being rolled out in March. Fixes for the EA189 1.2-litre engines will be approved in April/May next year as well as will be rolled out in June, as well as fixes for the EA189 1.6-litre engine will be approved in July/August/September before being rolled out in October.

He also outlined further details of the UK government’s independent testing of vehicles, to verify figures. While stressing that will such tests were at an early stage, as well as doing the item clear VW might pay for them, he added that will the Vehicle Certification Agency (VCA), which can be responsible for vehicle type approval, can be working closely with its French as well as German counterparts to retest vehicles via a variety of some other manufacturers in order to avoid a duplication of effort. He said the results might be reported inside spring.

Volkswagen could buy back affected vehicles in Europe

Volkswagen can be preparing to buy back some of the vehicles affected by CO2 irregularities in Europe, as the fallout via its emissions scandal continues.

According to the Financial Times, if VW’s re-testing of those affected vehicles reveals that will CO2 emissions have been understated by more than 10%, then customers will contain the opportunity to sell their cars back to VW at the current market value.

Speaking to the paper, a Volkswagen spokesman said: “We have to think that will maybe people will give the vehicle back. When we contain the [test] figures there could be a chance for people to say ‘I can hand back my car because you told me the wrong number’.”

A statement via Volkswagen says the company has identified 430,000 VW, Audi, Skoda as well as Seat designs via the 2016 design year which are affected by CO2 irregularities, which form part of the 800,000 total revealed last week.

Customers affected by the CO2 irregularities can expect to receive an official letter via VW inside coming weeks.

VW to offer cash incentives

Earlier This specific month, the item emerged that will Volkswagen might offer cash incentives of up to £1500 to existing UK customers as the item tries to avert the potential sales affect caused by the emissions scandal.

Dealer correspondence leaked to Autocar shows that will in response to concerns via VW’s British sales network, the company can be going to top up any discounts offered to existing customers trading in a VW of any age that has a further cash incentive – £400 on the Up city car, rising to £1000 on the Golf as well as Passat, as well as £1500 on the Touareg as well as Sharan.

The VW advice tells dealers, “This specific Insentif can be in addition to current tactical as well as does not impact your ability to determine the selling cost of the vehicle.” the item adds that will the offer will last until the end of January 2016. some other vehicles eligible for a £1000 incentive include Golf SV, Cabriolet as well as Estate, Beetle as well as Beetle Cabriolet, Scirocco, Jetta, Touran, Tiguan, CC as well as all electric vehicles.

VW’s British sales dipped slightly in October – along with those of several of its rivals, as the official figures dropped for initially in 43 months. However, market analysts suggest that will a large number of potential buyers are delaying their purchase – as well as VW’s loyalty Insentif can be clearly designed to negate that will issue. the item mirrors a scheme introduced inside United States, where existing customers can get up to $1500 off selected designs.

A VW UK spokesman said, “Any a new scheme can be designed to react to trends inside market, as well as you could say This specific does the same. We think This specific can be an attractive offer for existing owners.”

German emissions investigators target 23 different manufacturers

German automotive industry regulator Kraftfahrt-Bundesamt (KBA) has announced the item can be conducting independent emissions tests on cars as well as vans made by 23 different marques.

In a statement, the KBA said the tests were being conducted as a result of the Volkswagen emissions scandal, however also suggested that will accusations of cheating elsewhere inside car industry had been made. the item cited “verified indications via third parties regarding unusual pollutants emissions“.

“Since the end of September, KBA has been investigating whether further manipulation of emissions, of nitrogen oxides in particular, can be taking place inside market,” said the statement.

the item added that will the item had already tested two-thirds of the vehicles named, comparing laboratory test results with real-world figures, however did not give any clues as to the results.

All of the KBA’s tests are believed to be focused on diesel engines.

VW Group admits 800,000 cars may have false CO2 ratings; Porsche as well as petrol engines implicated

In early November, the Volkswagen Group was plunged into further crisis after admitting that will up to 800,000 petrol as well as diesel-powered cars had their CO2 as well as mpg ratings wrongly certified.

In a statement, VW revealed: “Under the ongoing review of all processes as well as workflows in connection with diesel engines the item was established that will the CO2 levels as well as therefore the fuel consumption figures for some designs were set too low during the CO2 certification process. The majority of the vehicles concerned have diesel engines.”

the item also pledged to “immediately start a dialogue with the responsible type approval agencies regarding the consequences of these findings”. The statement also described the situation as a “not yet fully explained issue”.

A VW spokesman confirmed that will the latest scandal affects AudiSeatSkoda as well as VW cars with what are described as “smaller” engines. Reports suggest that will cars powered by the 1.4-litre four-cylinder petrol engine with Cylinder On Demand technology are affected. Further reports suggest that will VW BlueMotion diesel designs with three as well as four-cylinder diesel engines are also affected.

The company said the item has set aside two billion euros (£1.4bn) to cover the cost of This specific latest revelation, although the item cautioned that will the item might need to consult officials before fully understanding the legal as well as econimic implications of the discovery. the item has not said whether the item will compensate owners of affected cars.

inside statement, Matthias Müller, CEO of Volkswagen, said: “via the very start I have pushed hard for the relentless as well as comprehensive clarification of events. We will stop at nothing as well as nobody. This specific can be a painful process, however the item can be our only alternative. For us, the only thing that will counts can be the truth. that will can be the basis for the fundamental realignment that will Volkswagen needs. The Board of Management of Volkswagen AG deeply regrets This specific situation as well as wishes to underscore its determination to systematically continue along the present path of clarification as well as transparency.”

The VW statement also stressed that will the safety of the vehicles affected can be in no way compromised.

Meanwhile, the Supervisory Board of the VW Group issues a separate statement expressing alarm at the latest discovery. the item said: “The Supervisory Board can be deeply concerned by the discovery of irregularities found when determining CO2 levels for the type approval of Volkswagen Group vehicles. The Supervisory Board as well as the special committee set up for the purpose of clarification will meet inside very near future to consult on further measures as well as consequences. The Supervisory Board will continue to ensure swift as well as meticulous clarification. In This specific regard, the latest findings must be an incentive for the Supervisory Board as well as the Board of Management to do their utmost to resolve such irregularities as well as rebuild trust.”

VW EA288 engine given the all-clear

Following a previous rumour of more widespread cheating, Volkswagen was forced to issue a statement saying that will its EA288 engine does not contain the ‘defeat device’ software that will has plunged the company into crisis.

German news agency DPA had reported that will early EU5-compliant versions of the EA288 motor – a unit derived via the EA189 design that will’s been at the heart of the emissions scandal – were under scrutiny by VW engineers as they tried to establish the full extent of the problem.

VW itself issued a statement confirming that will the item was examining the engines – however currently the item says that will process has been completed as well as that will “no software constituting an improper defeat device as defined in law can be installed in vehicles with EA288 engines”.

The conclusion can be an important one for the troubled German a new because the item could have faced millions of further recalls if the EA288 engines – sold in 1.6- as well as 2.0-litre versions across the VW Group’s range of brands – had been found to contain the code that will sparked off the emissions scandal.

VW’s statement added, “completely new vehicles of the Volkswagen Group offered within the European Union with those engines comply with legal requirements as well as environmental standards.”

UK recall ‘won’t be mandatory’

The UK’s Department for Transport has confirmed that will the item won’t be issuing a mandatory recall for cars affected by Volkswagen’s emissions scandal in This specific country.

Speaking to Autocar, a DfT spokesman confirmed that will the UK won’t follow the example set by the German authorities in issuing a mandatory recall for affected cars. Volkswagen has already started off a voluntary recall program for cars in This specific country, however the DfT has made clear that will “This specific can be VW’s position as well as VW’s problem.”

“We will continue to put pressure on VW to make sure This specific happens as quickly as possible,” said the spokesman “to ensure people inside UK can have these problems fixed.

“The government has been putting pressure on VW to address these issues quickly. The government expects VW to set up the next steps on how they are going to correct This specific problem as well as support owners inside UK. inside past few weeks the Transport Secretary has spoken to the German Transport Minister about the actions of VW, as well as has been reassured that will the German authorities are working closely with VW.”

In Germany, the federal transport authority, the KBA, can be forcing Volkswagen to recall the 2.4 million cars inside country which have its ‘defeat device’ software installed.

Criminal enquiry targets “fewer than 10 staff”

Criminal prosecutors in German who are investigating the dieselgate scandal have identified fewer than 10 suspects, despite earlier rumours that will up to 30 staff could be implicated. Klaus Ziehe, spokesman for the prosecutors inside German city of Brunswick, told news agency AFP that will investigators suspect “more than two however a lot fewer than 10 people”. 

VW’s UK boss faces MPs

Last month, Volkswagen UK boss Paul Willis admitted that will his company’s so-called ‘defeat device’ did affect the results of emissions tests in Europe.

Previously, the German a new has only confirmed that will the software-based emissions cheat was present on some vehicles in Europe – as well as had not outlined whether the defeat device was active during the NEDC emissions test used across the EU.

However, when asked during a 45-minute grilling via MPs on the transport select committee if the defeat device had been used during type approval testing for the UK, Willis admitted, “the item seems via what I understand – as well as I’m not an engineer – that will the system of gas regulation inside engine influenced the NOx output in cars that will we sell inside UK. These cars are type approved across all of Europe, of course, as well as they’re type approved in Germany, with separate people overlooking the item.

“We mishandled the situation in so far as our engines behaved differently within the testing regime to the real world. that will’s why we need to fix the cars, that will’s why we need to get the customers in, as well as that will’s why we need to put the cars right. We mishandled the situation, without a shadow of a doubt.

“the item seems that will inside test regime the engine behaved differently to the real-world situation via software. The software affected the flow of gas to the engine which reduced the NOx.”

Willis said VW reacted “as quickly as possible”

The session at the House of Commons was the first opportunity for the transport select committee – a cross-party Centeng made up of 11 MPs – to question VW representatives or the vehicle industry on the dieselgate scandal.

Willis came under particular pressure on the amount of time taken by VW UK to remove affected vehicles – around 4000 cars still on the market – via sale. He argued that will the firm had acted as quickly as possible, saying, “On 22nd September we were made aware by VW headquarters in Wolfsburg that will there was a potential problem with diesel engines. On 28th September we were getting more details as well as I phoned Mr McLoughlin [Patrick McLoughin, the Transport Secretary] to say to him that will as soon as I knew which vehicles were affected, I might voluntarily stop selling those cars. that will phone call took place at 3pm on 28th September.

“On 30th September, at 9am inside morning, I received the VIN numbers via the various different factories. as well as This specific can be the point: there were eight days between when we first knew the item affected Europe as well as when I stopped selling cars. as well as the reason for that will can be the complexity of the number of cars involved. There are 60 different designs, a few different brands, three different engines as well as two different transmissions.

“I found the VIN numbers out precisely at 9am, as well as at 1.30pm, once I had clarified the item with the computer systems, I stopped selling those cars voluntarily. the item took four hours as well as 30 minutes via the time I knew the affected cars until I took action – four hours as well as 30 minutes.”

Existing test comes under fire via MPs

Both Willis as well as the chief executive of the Society of Motor Manufacturers as well as Traders, Mike Hawes, were asked if the current emissions testing procedure was fit for purpose. Hawes admitted that will the difference between real-world figures as well as those provided by the NEDC could be “up to 30%”. “These figures are meant for a comparison process as well as always contain a disclaimer about the real world as well as This specific can be for some very sensible comparitive reasons,” he said.

“The test cycle dates back to the early 1980s as well as the industry recognises the item isn’t fit for purpose,” he added. “When you put a vehicle on the test cycle, for instance, all of the electronic devices that will you might turn on inside real world – air-conditioning, heating, sat-nav, Bluetooth – all of that will has to be switched off, by law, because when the regulation was created that will sort of technology wasn’t available. Then there’s the issue of real-world driving conditions – congestion, temperature, load, gradient – all huge as well as all ruled out by the test cycle to get a repeatable cycle.”

Hawes said he believes a more realistic testing cycle will be introduced on a compulsory basis via the beginning of 2017.

Willis also criticised the current testing procedure. He said: “If we look at the test regime on emissions, we know the item can be old-fashioned as well as not fit for purpose. We need completely independent tests that will look at all sorts of detail, like Euro NCAP, which uses real-world testing. We need to look at that will.”

“We have a duty to the public to reassure them [customers] that will our cars are safe. There can be no relation to safety with This specific issue however we do need to regain trust as well as we will do that will with transparency.”

Willis also apologised to VW customers inside UK saying: “Volkswagen has significantly let down its customers as well as the wider public. We recognise we’ve fallen short of the standards expected as well as we will take all the necessary steps to regain trust.”

VW UK could pay back missing tax to government

Willis has promised that will the VW Group will speak to Her Majesty’s Revenue & Customs to discuss any tax payments on vehicles that will may need to be made the wake of the dieselgate scandal. When asked if the firm had measures in place to compensate the Treasury for any revenues missed because of the defeat devices, Willis said, “I’m not sure there’s any clear evidence that will the CO2 emissions on these cars are different inside real world. however we can have a conversation downstream. The British taxpayer should not be out of pocket as well as if necessary, we will have a meeting with HMRC.”

The scale of VW’s global problem

In total, VW has said that will just under 11 million vehicles worldwide contain the software ‘defeat device’ that will was exposed in American emissions tests last month. While two-thirds are thought to be fixable that has a software upgrade, the item’s believed that will a total of 3.6 million affected VW, Audi, Skoda as well as Seat designs – those featuring the 1.6-litre edition of the EA189 turbodiesel engine – will require hardware modifications to correct the issue. US designs may require the addition of a urea tank, whereas European editions of the 1.6 are likely to need completely new fuel injectors.

VW’s completely new CEO Matthias Müller has pledged that will all affected cars will be fixed by the end of next year. He added: “Our most important task will be to regain lost confidence with our customers, partners, investors as well as the general public. The first step in This specific direction will be a fast as well as relentless examination as well as explanation. Only when everything comes to the table, only when things are completely explained, only then will people trust us again.

“Believe me, I too am impatient. however in This specific situation, in which we are dealing with four brands as well as many designs, care can be more important than speed.

“The technical solutions to the problems are in sight. By contrast, the business as well as financial consequences are not yet foreseeable.”

VW, Audi, Skoda as well as Seat launch websites for owners to check if they are affected

Volkswagen, Audi, Skoda as well as Seat have launched websites that will allow owners to check if their car can be affected by the emissions scandal.   

The VW site collapsed soon after launch as a result of the amount of traffic trying to access the item, however has since been functioning normally. Sites via AudiSkoda as well as Seat are all running without problem.

Government won’t hike tax bills

The Government has confirmed that will UK taxpayers will not be hit by a higher tax bill if the item turns out that will their cars were found to have cheated tests.

Transport secretary Patrick McLoughlin said: “The government expects VW to support owners of these vehicles already purchased inside UK as well as we are playing our part by ensuring no one will end up with higher tax costs as a result of This specific scandal.”

He also confirmed that will the Department for Transport has pushed for more clarity on the matter as well as that will the next round of tests will look at whether the software “can be being used elsewhere”.

“Neither cars, nor the testing facilities will be provided by the vehicle industry themselves”. VW has offered to pay just for This specific testing if the government requests the item does so.

VW’s remaining EU5 stock taken off sale inside UK

Following the scandal, Volkswagen Group UK took 4000 cars fitted with the EA189 engine off sale, pending investigations into how the item will remove the illegal software that will cheated US emissions tests while still ensuring the cars comply with all emissions regulations.

The move covered vehicles via Audi, Seat, Skoda, Volkswagen, as well as the cars as well as commercial vehicles affected represent around 3% of the Group’s total UK stock. They are required to be put back on sale once the Group’s modifications have been put in place.

A spokesman stressed that will the decision to withdraw the cars via sale was a voluntary measure, rather than a regulatory one. The vehicles remained on sale beyond the September 1 deadline for Euro 6 emissions regulations to come in to effect because legislation allows manufactures to clear stock of Euro 5 engined vehicles. VW has previously confirmed all of its cars fitted with the latest, Euro 6-classified engines are fully legal.

the item has also been announced that will anyone with an order placed for an affected car will be given the choice of withdrawing via the sale without penalty, taking delivery of the vehicle after the modifications have been fitted or taking delivery of the vehicle as soon as the item can be available as well as then having the required modifications retro-fitted.

More than 1.1m UK cars affected

The full number of cars to be recalled inside UK under VW’s voluntary scheme can be 1,189,906, as well as This specific can be spread across a few different brands inside VW Group. Volkswagen accounts for the majority, with 508,276 cars affected, while Audi has to recall 393,450 designs. Skoda also features a notable number affected, with 131,569. Seat as well as Volkswagen Commercial Vehicles are also involved, with 76,773 as well as 79,838 vehicles being recalled respectively.

In a statement, the firm said: “Customers with these vehicles will be kept informed over the coming weeks as well as months. All of the Group brands affected will set up national websites to update customers on developments.”

the item can be not yet known whether the owners of affected cars will be offered compensation. Various lobbying groups are claiming that will the potential loss of value to the cars should be reimbursed by Volkswagen.

A spokesman had previously confirmed that will VW will not rush a technical solution, preferring to focus on getting the item right. He said: “We don’t want to be fast – we want to be certain. Over the next days as well as weeks we will write to all affected customers as well as we will put in place free-of-charge fixes for all affected customers.”

However, the spokesman was unable to confirm whether the revisions might require the vehicles to be recertified for their emissions as well as economy figures.

The official VW statement reads: “An internal evaluation on Friday established that will a service procedure can be required for some a few million vehicles via the Volkswagen Passenger Cars brand out of a total eleven million Group vehicles worldwide. These vehicles via certain designs as well as design years (such as the sixth generation Volkswagen Golf, the seventh generation Volkswagen Passat or the first generation Volkswagen Tiguan) are fitted with Type EA 189 diesel engines.”

Why did VW cheat?

A senior source within the German car industry has shed light on the most significant outstanding question of the VW emissions scandal, namely why?

If the offending cars have all the emissions equipment on board to make the vehicle compliant with the regulations, why take such an enormous risk engineering inside ‘defeat device’ to bypass that will equipment?

“I expect the item was pressure on the engineers that will made them do the item,” said the source. “Remember This specific system was designed some time ago when emissions controls were not as sophisticated as they are currently, as well as the pressure to pass the tests might have been immense.

“as well as I imagine the reason they installed the defeat device can be that will without the item there might have serious consequences not inside laboratory however on the road, either with the vehicle’s performance, driveability, fuel consumption or some combination of the three.”

He went on to confirm that will technology has since evolved sufficiently for there to be no need for such devices today.

So why, then, did VW not simply stop using the defeat device when the item was no longer needed? “There are two possible reasons. First the item might likely have been integrated within the entire electronic architecture of the vehicle as well as not easy to remove, second to remove the item those responsible for its installation might have first to have flagged up the fact that will they’d put the item there, which they’d probably not be too keen to do…”

The source said he believed the defeat device was likely to be present also on VW products sold in Europe with the EA189 engine [since confirmed by a German minister] however almost certainly not active which he said, was “nothing like as bad as having active, however still illegal”.

He said also he believed that will VW alone was using such a device as well as that will all some other German car manufacturers had no equivalent systems on the cars they sold today.

The one remaining question can be who signed off the defeat device. Former VW boss Martin Winterkorn has denied knowledge of the item as well as his resignation, while inevitable, was no kind of admission of guilt.

Whoever was responsible, the item seems likely that will more heads will have to roll before the true picture emerges.

11m Audis, Seats, Skodas as well as VWs affected globally

While the VW Group has said that will 11 million vehicles worldwide are affected by the scandal, only 5m are via Volkswagen brand itself. Audi has revealed that will 2.1 million vehicles via its brand are affected worldwide, with 1.42 million of those being in Western Europe. Skoda has also revealed that will 1.2 million of its cars worldwide are affected by the scandal. Seat has said that will 700,000 of its vehicles are affected globally. 

A VW Group statement read: “As previously announced, all completely new Volkswagen Passenger Car brand vehicles that will fulfill the EU6 norm valid throughout Europe are not affected. This specific therefore also includes the current Golf, Passat as well as Touran designs.”

The figures also include 1.8 million light commercial vehicles.

SMMT: just because VW cheated, the item doesn’t mean the whole industry can be cheating

Speaking at a conference on air quality, chief executive of the Society of Motor Manufacturers as well as Traders (SMMT) Mike Hawes said: “Consumers are right to be concerned following the events of the past ten days. however we must remember, the actions of one company do not mean collusion. Implicating some other brands or companies might be unfair as well as wrong.

“the item might be wrong to penalise all diesels. The latest diesel vehicles are the cleanest ever – effectively reducing nitrogen oxide levels by 92% compared with earlier generations. They make a significant contribution to climate change targets, an environmental challenge which cannot be ignored.

“We recognise the current regulations for testing are out of date. We want, for consumers as well as our own industry’s integrity, a completely new emissions test that will embraces completely new technologies, as well as which can be more representative of on the road conditions.”

VW’s global meltdown

There have been calls for governmental probes in to VW’s actions via around the planet since the firm admitted cheating inside US emissions tests, including in Canada, Germany, Italy, South Korea, UK as well as the USA. The UK government has already announced the item will launch an inquiry into the scandal.

VW has put aside a fund of €6.5bn (approximately £4.7bn) to cover the costs of dealing with the issue, as well as says the item will adjust its financial targets for 2015 as a result. The matter came to light when the US Environmental Protection Agency (EPA) as well as the California Air Resources Board (CARB) revealed that will while testing 2.0-litre, four-cylinder diesel cars of the Volkswagen Group they detected electronic manipulations that will violate American environmental standards.

Reports have since surfaced that will Volkswagen was warned about the legality of its software as far back as 2007.

According to the EPA, This specific means that will the cars under investigation could be emitting up to 40 times the national standard for nitrogen oxide (NOx), which can be linked to asthma as well as lung illnesses. The cars affected are 2009-2014 Jettas, Beetles, Golfs, Audi A3s, as well as VW Passats built via 2014-15.

The issue will be investigated by the US Congress’s Oversight as well as Investigations Subcommittee.

“Strong emissions standards are in place for the benefit of public health,” said House Energy as well as Commerce Committee Chairman Fred Upton as well as Oversight as well as Investigations Subcommittee Chairman Tim Murphy in a joint statement.

“Manufacturers throughout the United States, as well as across the planet, have developed leading technologies to reduce airborne emissions within the limits set by EPA as well as state environmental agencies. However, reported EPA allegations that will certain Volkswagen designs contained software to defeat auto emissions tests raise serious questions,” they said.

“We will follow the facts. We are also concerned that will auto consumers may have been deceived – that will what they were purchasing did not come as advertised. The American people deserve answers as well as assurances that will This specific will not happen again. We intend to get those answers.”

A date for the US Congress hearing has yet to be set. Since the scandal broke the VW Group share cost has fallen by more than 50% via its 2015 high.

VW emissions scandal: how the item unfolded

The Volkswagen emissions scandal can be currently headline news, however the story has its roots in May 2014, when a study found higher-than-clamed emissions coming via two Volkswagen vehicles. Here’s our timeline of how the story unfolded.

May 2014 The West Virginia University’s (WVU) Centre for Alternative Fuels, Engines as well as Emissions publishes results of a study commissioned by the International Council on Clean Transportation that will found significantly higher-than-claimed in-use emissions via two diesel cars, a 2012 Jetta as well as a 2013 Passat. A BMW X5 also tested passed the tests. 

WVU alerts California Air Resources Board (CARB) as well as the Environmental Protection Agency (EPA) to the issue.

Summer 2014 Over the course of the year following the publication of the WVU study, VW continues to assert to CARB as well as the EPA that will the increased emissions via these vehicles could be attributed to various technical issues as well as unexpected in-use conditions.

December 2014 VW issues a voluntary recall of approximately 500,000 vehicles to address the emissions issue.

6 May 2015 CARB, in coordination with the EPA, conducts follow-up testing of these vehicles both inside laboratory as well as during normal road operation to confirm the efficacy of VW’s recall. Testing shows the recall has had only a limited benefit.

None of the potential technical issues suggested by VW can explain the higher test results consistently confirmed during further testing by CARB.

Summer 2015 CARB as well as the EPA make the item clear that will they will not approve certificates of conformity – necessary for vehicles to be sold inside USA – for VW’s 2016 design year diesel vehicles until the a new car adequately explain the anomalous emissions as well as ensure the agencies that will the 2016 design year vehicles might not have similar issues.

3 September 2015 During a meeting VW admits the item has designed as well as installed a defeat device in these vehicles inside form of a sophisticated software algorithm that will detects when a vehicle can be undergoing emissions testing.

18 September 2015 CARB as well as the EPA make their findings public, stating that will Volkswagen has violated two sections of the Clean Air Act, firstly by selling or offering for sale vehicles that will did not comply with their certificates of conformity, as well as second by manufacturing as well as installing into these vehicles an electronic control module capable of switching its calibration to beat the emissions tests.
