VW emissions software update - disaster

Golfgorfield

So i own a 2010 Golf GTD with DSG.
I received the letter to have the car made legal again for arguments sake amd decided to let my vw dealer do ot when in for service.
Its a 60,000 mile very well maintained with all main dealer stamps.
The car pulls like a train through the gears and when in sport mode it holds the revs in the high torque band brilliantly and is a joy to drive.

Well it was.......

After the software upgrade ive driven it over the weekend and it is certainly not the car it was, it feels much slower and its much more revvy and much less torquey.... in sport mode it doesnt hold the revs like it did and the dsg has become a bit dopey, theres also a slight vibration/wobble under acceleration at low speed which has appeared.

Has anyone any experience of this situation?
Im raging i got it done at all now.
I have phoned VW who stated they guarantee the car should feel exactly the same... just like they guaranteed all their engines were within emissions laws........

Has anyone noticed any differences after they had theirs done?

BBC exposes the truth about how the British government's car and fuel tax strategies encouraged switch to diesels:

Why officials in Labour government pushed 'dash for diesel'

Of course, it wasn't just them.
The Greens here pushed for a CO2-based taxation system too, ignoring the fact that diesel's are harmful to the environment in other ways.

And the trend to more diesels was Europe-wide, so I guess there was a much larger collusion.

We had this update applied on our ‘13 Audi A4 last month. I was hesitant tbh with so much scaremongering talk about it on here and elsewhere but I genuinely can’t tell any difference in the car since. It drives exactly the same as it did before and no issues - touch wood!

And that's the reality for majority of the drivers.

Does anyone know if during the emissions update if VW changed the gear change points on the dsg box? Thinking the box it way too eager to change up to the higher gears leaving the engine at a really low rpm, almost laboring.

Sport mode solves the issue :pac:

Main reason I opted to let them do it was, I reasoned in my own head that Audi would probably be more accommodating with any future engine / exhaust related issues (and hopefully we never have any) if I had let them apply their update...

The software might be updated routinely if new version made available by the manufacturer.

How many VW drive on our roads without owners not having a clue how to treat the turbocharger? How many trusted turbo mechanics there are?

I'd have no clue as to the answer to either of those questions.

Had JCD been running a Korean car no update would have been needed ( it seems Koreans dont lie about emissions) and probably all the other work would have been covered by warranty.

Is the what Made in Germany has come to ?

I hope not i went out and bought a bmw to replace my crappy passat

I get where toyotafanboi is coming from, but I dont think they have taken into account at all the knock on effects of this update on the cars.
No-one is claiming its bricking perfect new shiny engines. It is putting alot of pressure on (mostly) older parts and for lots of people its turning out to be enough pressure to cause failure in their vehicles.

I get the point that you made about it being easy for one mechanic to blame another, but this guy showed me 6 turbos taken apart in his shop that he said where from the same kind of issues i had and they were only from past 2 weeks, he said he is geting at least 8 or 9 a month from volkswagon thats alot (at least to me it seems).

In my case the update was applied without my permisson, so thats a big plus in my dispute with them apparently.

VW are German. Germany is the most powerful member of the EU. There won't be any buy backs. Simples.

So are you suggesting there are no laws that protect consumers from sellers falsifying specifications?

Im not suggesting anything. I'm asking what laws have been broken.
In America they broke laws and were forced to take action to rectify the resulting problems. What laws have they broken here that would warrant any remedial action apart from what crap theyre doing.

When the company offered to take the car back, Sarchiapone said she agreed and received $2,000 cash plus forgiveness for the $18,000 she owed on the car.

That doesn't appear to be the case here though, is it?

No, but they do take reasonable precautions against this. It's easy to make a good judgement call based on a 5-10 minute inspection of a vehicle but it's impossible to get it right 100% of the time I suppose.

And all the others on here who have had similar issues and got negative responses from their dealers and VW! So, I don't agree with your point as a given at all.

Have we any other examples of this? The only people who seem to get no satisfaction are people who's butt dyno tells them their 105bhp diesel is slower than it used to be. Anyone who seems to have tangiable issues with components get rectification work.

The point is, if you change how the car operates (i.e. the software update) and that causes downstream issues in the same sub-system (emissions control) then VW have to take responsibility for those downstream issues. I understand the DPF and/or EGR might have already been partially failing but there would probably have been thousands more miles without issue if the update was not done as those emissions controls were effectively being bypassed pre-update.

They have publically said that they will. That's why I don't understand why the previous poster didn't get his issues fixed for free, but we only know one side of the story and by that I'm not necessarily saying the poster is wrong.

In fairness, all cars are checked before the update is done, they are checked to make sure there are no faults stored, that the DPF soot content is acceptable and that the EGR and DPF are present and operational. No check is foolproof however but efforts are made to avoid situations like this.

The last thing dealers need is post update cars returning with issues like these.

... by reseting this without actually working on the dpf...

^^ this is the crux of the issue

VW have an emissions issue, they are applying a software fix which works the EGR harder and if you have a car that is already sick due to the EGR not being used enough or an older car not clearing the DPF due to too many short journeys (hence no regeneration) then the software fix is going to blow "stuff".

The issue is they are applying the fix without checking the EGR and DPF and hoping everything is going to be OK. That works for most cars but leaves some people with big repair bills. It's not the owners fault.

If I were you and they applied the software update without my express permission, which appears to be what you said, I'd press hard via my solicitor. I bet they will pay up. I've got money back from VAG Dublin before(€1800, for a timing chain) just by sending an email!

To be fair the easiest thing for one mechanic to do is tell a layman that another mechanic is wrong, for reasons they don't understand.

It does sound like your car had underlying issues though and unfortunately VW threw an update into the mix. Hundreds of cars a day get the update with no knock on issues.

What mileage is on the car?

Unfortunatley (considering how much was spent on the thing) it was written off in a crash 2 months back but im nearly sure it was 140 km

That said it sounds like your car had health issues before the update.

Know they refused when asked as they said the failure of the egr was due to the dpf failure and no fault of the installation of the new egr or the fitting of the egr.

Turbo failure has absolutely nothing to do with the update. I cannot think about any logical connection.

I guess one of the injectors failed, created tons of soot blocking the EGR and DPF, diesel dissolved the oil killing the turbocharger...

Or the turbocharger started leaking oil to the exhaust, blocked the DPF and increased pressure killed EGR.

well I was refered by my local mechanic to a polish guy who has a garage that specialises in refurbishing turbos and egr jobs for a few different main dealers, he was saying in his opinion what most likely happened was that due to the first egr being blocked by soot in the first place the dpf would have been in need of either replacment or at least regeneration depending on how bad it was. he suspects they just didn`t look at it at all.

He then said most likely after applying the update and the new egr that any faults on the ecu would be reset, and by doing this the ecu would assume that the dpf had either been replaced or regenerated.

So apparently the ecu will limit (something or other I cant rememebr im not a car guy) when it knows the dpf is full above a certain level.

by reseting this without actually working on the dpf, the ecu removed the limits putting more pressure and blocking( an admittidely already under pressure dpf). with the dpf now blocked the exhaust gas had nowhere to go and the pressure had to go somewhere, that somewhere being blowing out the turbo and new dpf.

He informed me he had seen this happen to several cars from various dealers, and was not surprised. He also said that the dealer informing me to drive the car for a week before coming back in with the warning light on the dash was madness.

he also said he checked the log and that all faults had been cleared on the dates the car was in the main dealer.

he said there was no way they could have missed this, and in his opinion that is incompetence on the mechanics fault who worked on the car.

to be fair this could all be gobbledegook i am no expert on engines.
all i know is my solicitor said it will take some time to get to court but she expects it to get settled before this in my favour( though i suppose they would say this anyway)
