A6 engine/gearbox problems

[S2thet]

Hey guys ive owned my a6 for 7 months. Its a 2012 s line 2.0 auto. A few weeks bk i had tyres changed and they damaged an alloyZ they put rhe small spare on for a few days when the alloy was repaired. Since then ive been having warning lights stating tyre pressure and gearbox malfunction was wrong but i can continue driving. I fixed the pressure but the warning light still appears. This week ive had another warning light saying stabilisation is weong and the car wont start. Its as if im not applying the foot brake when tryin to press the start button. Ive googled the problem and it seems a few people have had the issue but no answers. I took imrhe car to an audi master tech they reset the computer and it was grea for an hour. They cannot find any problem when running diagnostics. The car has only 40k so not alot really. Audi have a 4 week waiting list to be seen aswel. Anyone ever heard or know of anyone that can help. Cheers guys

Hi Stephen..welcome to the club!

Sorry to hear that you have been experiencing problems with your Audi.

I would as a preliminary check see that the tyre profiles and sizes are the same all round as this could cause the rotational speed to be different across the axles.

I hope someone who has experienced this problem can help you further.

Let us know how you get on    Regards,    Trevor  - Admin

Hi guys i got over the last problem apparantly it was sumin in the ecu it cost me £400 had nothing to do with the tyres. Audi contributed £18 for the part which was pathetic theyhad the car for 3 days hence the £400. I cant believe im gettin more problems already. The car is an s line 2.0 automatic on a 12 plate! Ive lost the reverse gear?!! It takes forever to move backwards but eventually it does at about 5000 revs so literally flys backwards . Has anyone ever experienced this i cant see much about it online?? Any help appreciated thanks guys

If you've lost reverse gear then it has to be related to your original fault which I thought would have been diagnosed when it was in for repair previously.

Sounds expensive though
