I have a 2004 audi a4 3.0 v6 quattro. I was driving home from work and lost control and went over a snow bank, got stuck and rocked it back in forth in reverse and drive (not like switching gears back and fourth, just rocking it in reverse, then got it out in drive) well I noticed when I got out of the snow bank drive felt like it had no power and would rev limit around 2-2.5k so I got home and tried to check it out, I noticed the dash didn't show what gear I was in and the tiptronic manual selectors didn't work either. Reverse doesn't have this problem, and neutral and park will rev anywhere just fine. It had the code p0811 which says its clutch slippage. Please help!!!
