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. It said on the dash that the gearbox was overheating but we hadnt used the car
