effect of diesel scandal software upgrade

[ujtordai]

Hi All,

 

What is your (who involved into this) experience after diesel scandal software upgrade?

What is the effect of software upgrade in fuel consumption acceleration, driving dynamics etc.

Supposedly the fuel consumption is increased about a half liter.

What is yours experiences?

What is the truth?

(I have y2010 Skoda Superb II. 2.0 CR TDI DPF engine code is CFFB)

 

Thanks in advance

There is a lot of discussion on your questions here:

Short answer is there's a lot of talk but no hard evidence of any effect.

There has been no noticable difference since the upgrade to my MY2014 Superb SE CR140.

 

It still only uses half a tank of diesel driving from Milton Keynes to the Cairnryan ferry port.

My Superb 2.0 TDI cr is march 2015 and software update has created a rattle around 1500 - 2000 rpm, mostly on a light throttle. Well documented problem with tiguans but not, so far at least, with the Superb. Skoda have tested it for a week and tell me it's fine,which its not. It's ruined the car and the total lack of interest from Skoda makes me feel this might be my last Skoda, after 5. I personally wouldn't advise having it updated.

Thanks for a concise view and clear advice.

If they force me to do the "fix" - I'll request rolling road test before and after the fix.

If they refuse - I'll pay by myself so there will be hard proof.

[James@RRG_Skoda_Rochdale]

You are free to decline the update, there's is absolutely no stipulation anywhere that states it is mandatory.

[jafo]

They could insist as there is still some warranty left ...

And you're 100% sure this isn't just something that has been there before but now after the update you've noticed it? Just to be able to find something wrong with the car and blame it on the update? 

[G Bain]

100% certain. I've had the car since new and know exactly all the noises it made up to the update at first service at 16,500 miles. There is now a definite diesel type clatter as described. Many tiguan owners have experienced similar noise. Refinement of engine has been destroyed. The update is not a 'patch' to remove defeat device but completely over rights ecu. So fuelling at low revs is changed causing this rattle it seems.

[G Bain]

I must also add that the day after update even my wife commented about the 'rattle' so it was noticeable to her as the passenger. The mechanic tells me that my update was 9979, which is higher than the so called software update- update fix to Tiguans with rattles. See Honest John website Tiguan reviews.

[James@RRG_Skoda_Rochdale]

It depends on what ecu is fitted to the vehicle, some have a patch update, others have a full reflash.

Why no-one seems to be using VCDS to log EGR activity over a given journey before and after the 'fix' continues to puzzle me.

Depends if any VCDS users have had the update done

 

I certainly have no intention of having my car updated at this stage and if it is done for me I'll put the current software back on...

So you could potentially do this logging, for someone who might be planning to get the update done? 

I just find it amazing that no-one seems to have considered this to be a useful thing to investigate. On diesel engines, after all, EGR's primary purpose is to reduce the production of NO_x gases, as I understand it. So increasing the amount of exhaust recycled would seem to me to be No.1 in the list of software mods required to pass EU5 without cheating.

 

I would love to volunteer but only have KKL cable + VCDS Lite, so not geared up for modern stuff.

Sure, I'm more than happy to log someone else's car pre and post update. I suspect most people who are actually worried or interested will have either already had the fix applied or be refusing it

[Breezy_Pete]

Good man.

[pabenny]

Just had my software fix done.  The dealer told me that there would be a sticker as evidence, but I've not found it.

 

Is there an official sticker or are they just spinning a line?

I hear they place the sticker in the spare wheel well in the trunk. some previous posts here said it would have 23R6 on it.

[pabenny]

Thanks - yes it's there, hidden below the black polystyrene surround.  Just a label stamped with the dealer name and the code written on.  The code is completely non-obvious.  For a recall as high profile as this, I would have thought there might have been something more 'official' looking.

Oh dear - they are wasting yet more millions on their Public Relations where you are concerned.

 

You said "high profile" and "recall" and "official". Don't you know you are meant to be saying "minor update" and "technical measure" and "regained trust".

A federal judge approved the $15bn settlement through which Volkswagen will compensate customers who bought cars that fail to meet pollution standards because it cheated in emissions tests. VW will offer to either buy back or fix the vehicles, though that fix has yet to be approved.

[jafo]

But it's for USA customers - not EU.
