Hi,

I am / was the proud owner of a 2017 380BHP A8L rocket ship until recently when my car went to Audi for an MOT. In their infinite wisdom Audi decided to implement a remap of the engine in response to the emissions scandal from a couple of years ago. ( Incidentally I did not ask for this work to be done ! ) 

Within 10 seconds of collecting the car it was obvious to me that something very, very bad had been done to the engine . It sounded and ran fine, but drove like a 1.3 fiesta ( sorry Ford, great car but not an A8) . It was completely not my car. On rejecting the car back to the service centre , having driven a further 5 miles, they admitted carrying out the remap, but said it should be indiscernible to the original . I pointed out that I had noticed the change within 10 seconds, without knowledge the change had been made.

I am currently having an argument with Audi, to get this reversed. For whatever reason Audi seem to be struggling with this ? Does anyone know why that would be so difficult ?

If any members know of a specialist in or around London who can put the original settings back into the car along with the NoX sensor which Audi also changed, I would be very grateful.

Thanks for your help 

Hi All, 

Does anyone have the official performance stats for the 2014-2017 A8 D4 4.2tdi model . eg the 0-60 , 30-70 acceleration times claimed, so I can compare against my dyno runs . If you do I would be very grateful ( preferably the L model , but the standard is also helpful 

Audi should not have do e this without your permission, fact. They have to have a signed form to say you agree to it, and it gets logged on a database. 

Did you sign anything when you dropped the car off? 

They say they cannot reverse it because I don't believe they are allowed to. 

The only cure is a independent remap if Audi won't do anything.  

Just before lockdown in March my 4.2 tdi needed the DPF cleaned and due to an issue with ECU updates, I had to book it into Audi.

When checking it in I was asked if it had been re-mapped and I replied “no idea” as I had only had it 6 months. But everyone needs to sign a disclaimer form.

It took 2 days to sort out as the updates proved troublesome and collected it on day1 of lockdown. Nothing appeared different drive wise and just carried on regardless.

Fast forward 4 months and I did take it for a re-map. When they placed it on the rolling road and plugged it in they came back with a surprise - 424 bhp.

Considering it was previously a funeral car and considering it had been through Audi, we were a bit confused as to this figure and with Audi still shut it was difficult to check. The re-map folk’s did mention that they have come across stock Audi’s with higher than normal bhp figures.

I know I have come across “Press Cars” with BMW’s and these do appear to be just that little bit faster which was backed up by the dealers.
