VW Emission Fix - Epic faliure

[greenstripe]

My Girlfriend has a 62 plate VW Golf MkVI DSG with the 2 litre 140ps Diesel Engine. She had the emissions software update done 3 weeks ago. She hadn't mentioned to me that the car had been making a noise 'a bit like a hairdryer under acceleration' for two days prior to a break down where the car lost all power and cut out immediately after starting. I was away so not able to see it for myself but assumed it was probably a boost leak. The car was towed to a VW dealership - who diagnosed that the turbo had failed and spat oil everywhere and the damage was a minimum of £5000 pounds in parts alone to rectify, however VW were going to pay for the full repair.

 

The car is now fixed and has had a new turbo charger, EGR system and DPF fitted. They were very vague, but said that the failure had been caused by the emissions fix software update but wouldn't elaborate.

 

My girlfriend was without a car for a week, but aside from this and the associated stress, it has cost nothing, and the car seems as good as new.

 

Is this a common occurrence? Surely if this is happening to a reasonable number of cars, then VW group would be going out of business pretty quickly. Is it likely that they made some kind of c**k-up that caused this?

Im surprised they have admitted fault

they have been denying it's causing any problems all along

Best contact the DVSA (DfT)  because someone must be compiling reports of complaints and VW have figures for complaints and are giving a percentage on something or another. Failures might be a bit of an issue that should be highlighted.

Sounds like a bearing failure in the turbo if there was oil everywhere. Those sort of failures don't come out of nowhere like that. At best, the update may have hastened the failure by working it harder but that turbo was going to let go sometime in the next 6-12 months anyway.

 

Bearing failure in the turbo is often due to poor maintenance: if VW have been doing all the servicing on it up to now, that's probably why they ate the cost.

The fix runs the engine hotter does it not?

Might that have hastened the turbo's demise?

 

My mate has had the notice to bring his passat in. It's on 110k and running well, I've told him to avoid the fix. If it's not broken don't fix it. Especially on that mileage.

Hotter? Can't see why? Info source?

This seems a perfect point early in the thread for someone with all the knowledge to explain when VW do a Recall on a Euro 5 TDI with a Defeat Device in the Engines management / ECU what the VW Group came up with that has the vehicle perform as it did during EU Testing or sample vehicles did and now after the New Engine Management is applied what changes.

Is it warm up times, where the Torque is available in the rev range, is it when Regens might or might not happen?

Does the NoX actually reduce when being driven on the road or only under EU re-tests, and if VW Group did nothing illegal in the EU or during Type Approval and EU testing why are they doing The Fix'.

http://skoda.co.uk/pages/fuel-consumption-statement.aspx

 

If vehicles that are performing OK and have over up to 9 years and then after the New Engine Management Software there is a major harware component failure then tough titty on VW having to pay out Thousands of quid, they are paying out thousands of Dollars in the US on each vehicle they did fit Illegal Defeat Devices to and have admitted to those.

Because there is no 'Fix', or the owner will not accept 'A Fix', they compensate and buy back, but their the vehicles that have Defeat Devices are without doubt illegal, in Europe EU Governments let VW say what is or not and then wait for courts to make the final decision.

VW have Plead Guilty actually in the USA, same software, just different emissions and test requirements in the USA.

Here is the EU's press release on the topic of emissions testing and defeat devices: http://europa.eu/rapid/press-release_MEMO-15-5705_en.htm

 

They're quite clear on defeat devices being illegal: VAG's views don't come into it. Any of us accused of something will probably try and deny it until proven otherwise, and the legal system operated through the EU assumes innocence until proven otherwise. Their description of what constitutes a defeat device is in line with what VAG did.

 

A consortium of European motoring associations along with the Vienna University of technology ran back-to-back tests on a number of vehicles and found that NOx emissions on WLTC and BAB drive cycles improved substantially. They also did a RDE test (take the car out on the road with a mobile emissions lab hooked up to the tailpipe) and observed a reduction in NOx. http://www.skodaforhandlere.no/globalassets/20160627-oamtc_rk_27062016_en.pdf They also observed a modest improvement in CO2 emissions in this test, though real world driving is subject to a greater number of uncontrolled variables than a lab test.

We know all that you have posted those in threads for a couple of months now as have i.

 

So there are those with VW Group 2.0. 1.2 & now 1.6 TDI's that have had 'The Fix' and that are reporting 'issue' with their vehicles, 

so what was the changes carried out that had those testing getting the results they did, and what have the VW Group done wrong that 

has ended with others running not as before. Noisier if just that, or with the torque in a different rev range.

?

Or are these complaining and reporting issues all just imagining things?

Volkswagen hasn't explained exactly why it cheated, but outside analysts have a good guess. The NOx emission controls likely degraded the cars' performance when they were switched on — the engines ran hotter, wore out more quickly, and got poorer mileage.

 

Probably 'chemistry' the engine will burn cleaner when it's hotter but that might be best fore the longevity of mechanical parts or fuel economy.

 

I've read the same thing in a few places but that's the one I found quickly.

They want to avoid hotter combustion temperatures if they can. High temperature combustion leads to NOx formation which is what they're trying to reduce here. It's a catch 22 because higher combustion temperatures improve other emissions (CO, CO2, HC, PM).

VW Group Employees and Fan Boys / Girls can try passing failures off as just a coincidence after you had The Fix', and just a small number of vehicles 

but then the VW Group have not done many VW, Skoda, Audi, SEAT 1.6TDI CR's yet.

 

Small numbers maybe fail, well so far, but if it is your only vehicle you spent your money on what high paid VW Group employees think might be unimportant shows their ignorance really.

It is nice when VW Pay your wages and your cars are 'Management Perks'.

Girlfriend's car is in the "less than 1%" category then:
