23Q7 EA189 Software Update

[Hammer2001]

Had my letter from Audi saying action required on my car for the software update to rectify the emissions scandal.

Says it will take 30-60mins and to arrange to get it done ASAP.

They are also offering a mobile service to get it done at home/work.

Anyone had it done yet?
Any detrimental effects?

[Pat Cronin]

Had mine done on 8th June - 2011 SE model. Was in getting new rear discs and pads and Audi South Dublin offered to carry it out while there.

No issues, not noticed a single difference. Power/Economy/Smoothness all the same.

[Whippy53]

Why would you have it done? Why take a chance of them borking it up?

[A6S]

Something has to give if you ask me
If they were able to make these car right in the first place why didn't they?

[Gazwould]

Do not do , no no no no no no.

Just my opinion, but a few lost BHP/NM would be undetectable by a human. For those with a dyno, I think the only laws that apply regarding performance (Lemon Law etc.) relate to original manufacturer figures and there will be plenty of leeway. If you are thinking about getting it done it might be better to hold off for the independent lab/dyno tests to appear first.

Seems like a very distant possibility with everything else that’s going on and it would depend on when you plan to get rid of the car, but it might become compulsory. Things could change obviously (quite soon) but going by the select committee last year it was the full intent of the transport department.

Anyway, if it does become compulsory and you keep knocking it back could Audi be cheeky enough to charge you in a few years?

[A6S]

Is it me or did vw over think this emission cheat?
Was reading about the Mitsubishi cheat and all they did was put a few more psi into the tyres, nothing technical whereas vw put in a program in the software to achieve this 😄

[Gazwould]

It's a bit more than just a few bhp and torque .

Mpg aswell !

If it was possible to have this much performance and mpg with this little emissions they would of done it .

But they had to cheat because it was IMPOSSIBLE !

And so therefore are the false claims of a "fix" from a proven lying company .

[SMILEMAN]

Had mine done a couple of weeks back....no issues whatsoever.

Had mine done on my 13 plate A6 Avant last Friday (17th June). The only detremental effect I've noticed is the tears experienced from giving back the S6 Avant (!) courtesy car I've had for the last 3 weeks! :(

[Crasher]

Don't have it done, it can't be undone...

[markmck]

Just got the letter today - still not much info on the affects of the update online....

[Guest 2]

I've had mine done. MPG and performance have stayed the same.

[Crasher]

You are brave!

[A6S]

Is that the mpg on the dis or your calculated mpg?
It's not difficult to make the dis read whatever you want

Calculated brim to brim.

[A6S]

Calculated brim to brim.
That's good. So fuel economy isn't affected. Then it must be power. Won't be long before someone posts a before and after on a dyno

[Q7quattro]

I haven't received my letter re the update yet, as my nearest main dealer is 35 miles away , so round trip of 70 miles- will they refund my diesel costs ?

[Guest 2]

why would they refund your diesel?

[fest0r]

You can ask them, but probably better not to raise the subject of compensation on here :aargh4: ;)

[RhysoTDI]

Bloke I know was offered £25 diesel, some cleaning stuff and something else when his A4 went in for the recall. Think he took the diesel lol

[Whippy53]

yes, he does. lots!

[Crasher]

Yes, if it ain't broke, don't fix it. The recall is utterly pointless, unnecessary and a huge risk.

[MacHighlander]

Has anyone noticed any issues with increased engine noise after getting the fix applied?

I ask because this whole issue stemmed from the engineers trying to develop a way in which to lower the noise of diesel engines. Injecting more fuel into the engine caused it to run quieter, but increased emissions, and then the software was used to fool the emissions tests.

But if the fix involves removing the offending software, surely the engine noise must suffer?

[Crasher]

The noise theory is not proven yet, the official line is that in Europe the emissions test software workaround is benign as we do not have the same punitively high standards as the six states of the USA which use the CARB emissions standards. Having said that, it does not explain why the 1.6 needs a tea stainer in the AMM and yes, people have complained about increased diesel knock. The simple answer is to not have the recall done and ignore it, in fact insist it is not done if your car is at the dealers.

[A5WoodBurner]

I'm reluctant to have mine done too, mostly because of the "everything will be fine, don't worry" attitude of the letters from VAG, whilst providing no evidence of the effect (or not) of the changes. As I understand it, the "cheat mode" was originally developed as noise reducing strategy on other diesel engines (ie NOT the EA189's) but VAG engineers discovered they could use this mode during emission tests to reduce emissions. This makes me think that the change is basically to get rid of cheat mode & since no one ever drives their car in the manner or conditions that replicate the emissions test (don't get me started on that ;) ) then on that basis no-one should experience any difference because there isn't one. Of course that would mean the "we've taken advantage of updated diesel technology" claim in the letter describing the update is a load of baloney but why lie to correct another lie? I'm in the wait camp.

(don't get me started on that ;)

Don't get me started on wood burning stoves.....:biglaugh:

[markmck]

Well i've just had my second reminder letter for the recall and it to shall be ignored :)

[Hammer2001]

I no longer own an Audi, a growing family dictated swapping to a Seat Alhambra!, but I just received the letter from Seat for the fix to be done.
I believe the Audi and Seat use the same 2.0 TDI engine? So maybe of interest here.

In the Seat letter they state that the fix may increase the consumption of AdBlue, and as such will fill up the Adblue tank after the software fix has been applied, and in addition issue a card that will entitle you to a further five free Adblue top ups.

I'm still in two minds whether to get it done or ignore it!

[Crasher]

Does it run fine now? Do you want to take a chance screwing it up? What I don't get with people asking about having it done is WHY? I think it is part of our modern obsession with updates. If it ain't broke, don't fix it...

[a8 tech]

wise man say if not broken dont **** around with it :) 23q7

Wife’s 2013 Q5 needed adblue and I was out of country so she went into Audi dealer to get a refill. A week later, and she said “ I don’t know what the garage have done, but my car doesn’t have any pull anymore”. So I commented that all they did was put Adblue in - it can’t have affected performance. So she said actually they took it for an hour and a half, and was not happy to wait. They mumbled something about an update and when she questioned them they would not give a straight answer. Checking the paperwork it just says Completed Service Campaign 23Q7. We did not ask for this, and always stated not to do it before.
So my wife is not mechanically minded, not a racer, and would not have been looking for a change in performance, but she’s not happy. ******.

I am sure this must be illegal but the only way around this without a huge amount of arguing is an aftermarket remap, quite simply there is nothing the dealer can do about this no matter how much you scream, they do not have a solution on their system.

[auditer]

Hi MacHighlander, I do have this issues right after the EA189 s/w updated which done without my consent by dealer, it was a long story but cut it short the s/w has been updated and now the engine very very noises and I can't drive in it for more then 30 min's long and don't even mention get on to motorway, could you or anyone here can give me an advices what I can do? I has been search around and some said s/w update can be reverse by a specialist? anybody know about this? Much appreciate any help.

Brief update. Complained to ******* that car was not performing so they took car in for a check. No surprises,they said no faults. Then they said they had not applied the fix because the 2.0 Diesel does not require it.. Then they suggested that the reduced performance is because we put dirty fuel in it. The AdBlue paperwork clearly states they applied the EA189 fix. Not minded to believe them..

The CGLC engine is indeed part of the EA189 family so subject to the software fix. Filling the car with Adblue takes 5 minutes not 90 so clearly something else was done and if the invoice said it had an update that is likely to be the case. Not sure where you go from here as the dealer will not reverse the update

Go to another dealer and ask them for a printout of all services and updates that’s been applied to your car. If it’s on the list then there’s no ambiguity.
I will then threaten the dealership with a letter as they have changed/modified your car without consent. If the car is leased or on Audi finance then you technically don’t own the car so in theory Audi finance could give blanket authority for all their cars to get the update and you will have nothing to stand on I’m afraid.

[Gmonster]

There are some firms that can reverse the update at a cost.. get that done and charge back to dealer etc?

Updates that reverses it will be classed as a remap and will flag td1 as it’s not official Audi firmware/software.
Ok if you are out of warranty but risky if you are still in warranty.

Can this update be taken off with a remap? And would it affect the map of a remapped car? Sorry might be a dumb question

[Gmonster]

It will be a remap and will void all Audi warranties. Think it will be the only option tho as Audi can’t/won’t reverse it; don’t think there are any confirmed cases of this happening.

I have a 2013 2.0tdi 177bhp A6.. and have managed to keep it clean of the update ...and it has been in and out of Audi Hillington many times; no compensation to you I know..
