Hello!
My Audi A6 C5 Allroad 2.5 TDI AKE 2000 has run to some problems. During the weekend I was in the warm garage doing maintenance (changed CV joint and track rod end). After that I drove my car outside where was -25C, and noticed that my steering wheel wasn't straight. It was little bit to the left while driving straight. Next day after a very cold night, I did an test drive and everyhting was fine except that steering wheel was to the left. Until I noticed that the tiptronic didn't change gears at all.
On the dashboard where is visible current selected gear, there was all lights "on" like I had every gear in. P,R,N,S,D were all "on". Car was powerless, and even that manual gear select +/- didn't work. So i drived back home. After that I checked with VCDS I noticed it had the 4th gear in all the time. I checked the faultcodes and got only one code from transmission:
After that, I took TCU out and got it inside to warm up. I kept it in warm for 2 days, plugged it in again, heated car from inside, and deleted faultcodes. Fault gets back.
I have no idea what should I do next. Do I need to buy new TCU, or is there something else I should check before that?
Thanks for help!
