Hello,
Audi A4 B6 2.5TDI (bfc), 2003MY, 107000miles.
The first problem was with ECU as Vagcom showed two codes: 17134, 18149.
The ECU is now fixed and codes did not return again but is still the same problem as previously. When I select P or N and put my foot down the revs goes max. to 1200rpm. Second problem is that when I select D or R the car does not move on his own, I have to put my foot down and then it revs. to 1500rpm and then moves forward and after 2sec. stops, so is impossible to go quicker than 5mph
The gearbox is filled with new special oil for multitronics (4.6L). My service book shows that the previous owner has changed body valve unit at 50000miles and I am not the first person who touched ECU because date on ECU is 2007. When Audi's front wheels are lifted and I select D then it makes horrible noise and engine shakes and you can hear clicks( click,click,click and so on). I havent seen similar problem on the forum. Can any one help me ? Also I have all details from Vagcom (Voltage, Temp, speed, Current etc of 25groups)

Thank you
