VW emissions software update - disaster

1jcdub · 13-11-2017 05:55PM

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.

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

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!

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...

Sport mode solves the issue :pac:

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

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.

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?

how do you treat a turbocharger?

You're well able to google around the dos and don'ts.

It was the terminology I didn't get ..

But from your response I take it he meant 'how best to drive a car with a turbocharged engine?'

Oh, sorry for being obnoxious.

The most important thing is not to switch the engine immediately when you reach your destination. Let the turbocharger spin down and oil cool it down. In regular driving 15 seconds is enough, but after motorway driving I would let it idle for a minute at least. Some of the newer engines come with water cooling of the charger. It helps, but does not mitigate the issue completely.

When oil circulation is switched off, a hot turbocharger will boil oil and deposits will forms in the bearings, dramatically shortening the lifespan of the charger. Overzealous Stop/Start systems do contribute as well. It doesn't happen immediately - but that's one of the reasons some cars do 200kkm and some 40kkm to the first failure.

Some cars won't even stop engine for a while. I remember my colleague's car (Subaru IIRC), he turned the key, slammed the door and locked it - engine still ran for another minute or so.

Aftermarket turbo timer I'd say.

joujoujou · 16-11-2017 03:45PM

Maybe. I have no idea, just that's what I saw.

gctest50 · 16-11-2017 03:49PM

They should really have an electric pre/post oil pump on them

While there is some truth in this for high strung petrol turbocharged engines the reality is for a diesel turbo it makes no difference. Diesel egts are quite a bit lower than a petrol and the turbos don't run nearly as hot. I have dismantled dozens of petrol and diesel turbos and to be honest coking of oil is an almost non existant issue on most cars. I haven't had one turbo fail yet as a result of oil coking in the CHRA.
At motorway speeds you wouldn't even have 400 degree egt's, no need to let the car idle at all afterwards, not that it will actually hurt anything of course and the turbo will have spun down before you even touch the handbrake, its almost instant.

Was just out in the local VW dealers and was asking the service manager who I happen to know about the recall and he told me that VW are covering EGR, Injectors, high pressure pump, Exhaust gas temp sensors and a few other items 100% post the update being applied for 2 years.

I know EGRs tend to give hassle anyway on the 1.6tdi’s so seems like a no brainer if I’m getting 2 years warranty on them, but I haven’t heard anyone else talk about this coverage.. Anyone here have an EGR failure post update and got full coverage??

George Dalton · 27-11-2017 08:31AM

Yes, several of them. We actually have a 2014 Passat going in to VW this week to hopefully have it replaced.

Yes, I had an EGR fail first, and subsequently exhaust temp sensors fail post update and they were replaced no questions asked. It was annoying, but TBH, VW Dealer gave no hassle, no issue and just replaced the parts and gave a loaner car.

That’s good to know, especially when the EGR is prone to go anyway.

Haven't been following this thread,only discovered it now.i,ve a 2015 2.0l alhambra due into seat tomorrow for the emissions update.had planned on not having this done due to what i heard and read elsewhere.but been told by dealer not doing it isn't a option as I've a engine light and message showing on dash.it's related to a adblue issue on car and needs removing.what do you do???????

If it has adblue, it does not have the recall mentioned in this thread.

Some adblue models are effected.

It appears to be on their campaign website, referred to somewhat ironically as the "trust building measure".

I hope your right.i got a emissions recall letter on it some weeks back.was ignoring it till adblue light wouldn't go out after top up.

A US-based Volkswagen executive who oversaw emissions issues was sentenced to seven years in prison and fined $400,000 (€339,000) by a judge on Wednesday for his role in a diesel emissions scandal that has cost the German automaker as much as $30 billion.

Fall guy,

Hi All,

Has anyone got the Vw software emissions update done? If so how is your car preforming after it. As I got done and EGR warning light came on straight after it was done. The dealer replaced as "a gesture of good will" ... However there are warning lights constantly appearing on the dash(an Amber coil symbol light and engine management light) , car is going into limp mode, speedometer is sticking at 2k revs, when I get diesel the next day it would run bad, possible a fuel pressure issue... Last week my car gave up, will not start. I'm informed it is a fuel issue...I'd think it is because of the update? The dealers will not admit fault as my car was running perfect before the update and now I cannot drive it?

The dealer is looking for €500 to fix the latest issue but I am not paying it as it was volkswagens fault.

Any help or advise as to what to do greatly accepted

Any car that's had the emission fix will be covered by an additional 2yrs warranty on all emission fuel related parts egr, dpf, injectors etc from the date of the emission fix.

Where does it state this?

Is there any documents available on this?

Its my understanding that the injection event is changed with the "fix" the injectors now use multiple injections up to TDC whereas before they used one, this means a lot more work than before and consequently a shorter lifespan.
