VW admits This specific’s testing earlier generation of EA288 engine for emissions test cheat; UK vehicles affected by scandal won’t be subject to a mandatory recall


Volkswagen has admitted that will another batch of its diesel engines could contain the ‘defeat device’ software that will has prompted a recall of more than 11 million units worldwide along with also caused turmoil at the German supplier received a.

German news agency DPA will be reporting that will the EA288 motor – a unit derived coming from the EA189 design that will’s been at the heart of the emissions scandal – will be under scrutiny by VW engineers as they attempt to establish the full extent of the problem.

Current versions of the EA288 – those compatible with EU6 emissions regulations – are not suspected of carrying the software. yet VW has admitted, “additional generations of the EA288 are currently being examined.”

This specific declined to comment further, yet that will’s likely to refer to the EU5-compatible versions of the EA288, sold coming from 2012 onwards in sizes of 1.6 along with also 2.0 litres. This specific’s not known precisely how many additional vehicles could be affected if the EA288 will be determined to have featured the emissions test cheat.

UK recall ‘won’t be mandatory’

The UK’s Department for Transport has confirmed that will This specific 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 out a voluntary recall program for cars in This specific country, yet the DfT has made clear that will “This specific will be VW’s position along with also VW’s problem.”

“We will continue to put pressure on VW to make sure This specific happens as quickly as possible,” said the spokesman “in order that will people within the 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 along with also support owners within the UK. within the past few weeks the Transport Secretary has spoken to the German Transport Minister about the actions of VW, along with also has been reassured that will the German authorities are working closely with VW.”

In Germany, the federal transport authority, the KBA, will be forcing Volkswagen to recall the 2.4 million cars within the 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 within the German city of Brunswick, told news agency AFP that will investigators suspect “more than two yet a lot fewer than 10 people”. 

VW’s UK boss faces MPs

Earlier This specific week, 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 supplier received a has only confirmed that will the software-based emissions cheat was present on some vehicles in Europe – along with also 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 coming from MPs on the transport select committee if the defeat device had been used during type approval testing for the UK, Willis admitted, “This specific seems coming from what I understand – along with also I’m not an engineer – that will the system of gas regulation within the engine influenced the NOx output in cars that will we sell within the UK. These cars are type approved across all of Europe, of course, along with also they’re type approved in Germany, with separate people overlooking This specific.

“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, along with also that will’s why we need to put the cars right. We mishandled the situation, without a shadow of a doubt.

“This specific seems that will within the 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.”

UK’s 1.6 diesel fix won’t need a brand new urea tank

Of the 1.2 million affected cars within the UK, Willis said 400,000 – believed to be those with the 1.6-litre design of the EA189 diesel engine – could need additional corrective work beyond a software upgrade, including brand new fuel injectors, along with also that will This specific could “take a longer period of time”.

However, he said that will the installation of exhaust after-treatments, likely to be fitted to some cars affected within the US within the form of a urea tank, could not be necessary within the UK. “My understanding will be that will the addition of urea tanks will be not part of the solution in Europe,” he stated. “There’s a different technical configuration on the cars along with also different technical regulations apply. My understanding will be that will the costs are different, too.”

The remaining 700,000-odd units – 2.0-litre diesels along with also around 30,000 1.2-litre diesels – can be fixed by software patches alone.

While details on the technical fix Volkswagen will use to correct the affected cars remain limited, Willis said that will customers should notice no difference in fuel economy once the fix has been applied. “Our engineers are working to the brief that will there cannot be any change in miles per gallon,” he said.

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 – coming from 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 along with also 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 could voluntarily stop selling those cars. that will phone call took place at 3pm on 28th September.

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

“I found the VIN numbers out precisely at 9am, along with also at 1.30pm, once I had clarified This specific with the computer systems, I stopped selling those cars voluntarily. This specific took four hours along with also 30 minutes coming from the time I knew the affected cars until I took action – four hours along with also 30 minutes.”

Existing test comes under fire coming from MPs

Both Willis along with also the chief executive of the Society of Motor Manufacturers along with also 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 along with also those provided by the NEDC could be “up to 30%”. “These figures are meant for a comparison process along with also always contain a disclaimer about the real world along with also This specific will be for some very sensible comparitive reasons,” he said.

“The test cycle dates back to the early 1980s along with also the industry recognises This specific 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 could turn on within the 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 along with also 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 coming from the beginning of 2017.

Willis also criticised the current testing procedure. He said: “If we look at the test regime on emissions, we know This specific will be old-fashioned along with also 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 will be no relation to safety with This specific issue yet we do need to regain trust along with also we will do that will with transparency.”

Willis also apologised to VW customers within the UK saying: “Volkswagen has significantly let down its customers along with also the wider public. We recognise we’ve fallen short of the standards expected along with also 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 within the real world. yet we can have a conversation downstream. The British taxpayer should not be out of pocket along with also 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 develop 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, This specific’s believed that will a total of 3.6 million affected VW, Audi, Skoda along with also Seat types – those featuring the 1.6-litre design of the EA189 turbodiesel engine – will require hardware alterations to correct the issue. US types may require the addition of a urea tank, whereas European editions of the 1.6 are likely to need brand new fuel injectors.

VW’s brand 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 along with also the general public. The first step in This specific direction will be a fast along with also relentless examination along with also 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. yet in This specific situation, in which we are dealing with four brands along with also many types, care will be more important than speed.

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

VW, Audi, Skoda along with also Seat launch websites for owners to check if they are affected

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

The VW site collapsed soon after launch as a result of the amount of traffic trying to access This specific, yet has since been functioning normally. Sites coming from AudiSkoda along with also 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 This specific 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 within the UK along with also 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 along with also that will the next round of tests will look at whether the software “will 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 This specific does so.

VW’s remaining EU5 stock taken off sale within the UK

Following the scandal, Volkswagen Group UK took 4000 cars fitted with the EA189 engine off sale, pending investigations into how This specific 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 coming from Audi, Seat, Skoda, Volkswagen, along with also the cars along with also 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 coming from 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.

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

More than 1.1m UK cars affected

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

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

This specific will 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 This specific right. He said: “We don’t want to be fast – we want to be certain. Over the next days along with also weeks we will write to all affected customers along with also we will put in place free-of-charge fixes for all affected customers.”

However, the spokesman was unable to confirm whether the revisions could require the vehicles to be recertified for their emissions along with also economy figures.

The official VW statement reads: “An internal evaluation on Friday established that will a service procedure will be required for some a few million vehicles coming from the Volkswagen Passenger Cars brand out of a total eleven million Group vehicles worldwide. These vehicles coming from certain types along with also 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 within the ‘defeat device’ to bypass that will equipment?

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

“along with also I imagine the reason they installed the defeat device will be that will without This specific there could have serious consequences not within the laboratory yet 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 This specific was no longer needed? “There are two possible reasons. First This specific could likely have been integrated within the entire electronic architecture of the vehicle along with also not easy to remove, second to remove This specific those responsible for its installation could have first to have flagged up the fact that will they’d put This specific 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] yet almost certainly not active which he said, was “nothing like as bad as having active, yet still illegal”.

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

The one remaining question will be who signed off the defeat device. Former VW boss Martin Winterkorn has denied knowledge of This specific along with also his resignation, while inevitable, was no kind of admission of guilt.

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

11m Audis, Seats, Skodas along with also VWs affected globally

While the VW Group has said that will 11 million vehicles worldwide are affected by the scandal, only 5m are coming from Volkswagen brand itself. Audi has revealed that will 2.1 million vehicles coming from 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 brand 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 along with also Touran types.”

The figures also include 1.8 million light commercial vehicles.


SMMT: just because VW cheated, This specific doesn’t mean the whole industry will be cheating

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

“This specific could 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 along with also our own industry’s integrity, a brand new emissions test that will embraces brand new technologies, along with also which will be more representative of on the road conditions.”

VW’s global meltdown

There have been calls for governmental probes in to VW’s actions coming from around the entire world since the firm admitted cheating within the US emissions tests, including in Canada, Germany, Italy, South Korea, UK along with also the USA. The UK government has already announced This specific 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, along with also says This specific will adjust its financial targets for 2015 as a result. The matter came to light when the US Environmental Protection Agency (EPA) along with also 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 will be linked to asthma along with also lung illnesses. The cars affected are 2009-2014 Jettas, Beetles, Golfs, Audi A3s, along with also VW Passats built coming from 2014-15.

The issue will be investigated by the US Congress’s Oversight along with also Investigations Subcommittee.

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

“Manufacturers throughout the United States, along with also across the entire world, have developed leading technologies to reduce airborne emissions within the limits set by EPA along with also state environmental agencies. However, reported EPA allegations that will certain Volkswagen types 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 along with also 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% coming from its 2015 high.

VW emissions scandal: how This specific unfolded

The Volkswagen emissions scandal will be currently headline news, yet the story has its roots in May 2014, when a study found higher-than-clamed emissions coming coming from 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 along with also Emissions publishes results of a study commissioned by the International Council on Clean Transportation that will found significantly higher-than-claimed in-use emissions coming from two diesel cars, a 2012 Jetta along with also a 2013 Passat. A BMW X5 also tested passed the tests. 

WVU alerts California Air Resources Board (CARB) along with also 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 along with also the EPA that will the increased emissions coming from these vehicles could be attributed to various technical issues along with also 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 within the laboratory along with also 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 along with also the EPA make This specific clear that will they will not approve certificates of conformity – necessary for vehicles to be sold within the USA – for VW’s 2016 design year diesel vehicles until the supplier received a car adequately explain the anomalous emissions along with also ensure the agencies that will the 2016 design year vehicles could not have similar issues.

3 September 2015 During a meeting VW admits This specific has designed along with also installed a defeat device in these vehicles within the form of a sophisticated software algorithm that will detects when a vehicle will be undergoing emissions testing.

18 September 2015 CARB along with also 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, along with also second by manufacturing along with also installing into these vehicles an electronic control module capable of switching its calibration to beat the emissions tests.
