Hi everybody, i have a Audi A4 2007 2.0T tip tropnic and i have the same problem (see video)

This rpm fluctuation stop after around 10 minutes. No error code detected with the ODB Scan. Data from the torque converter are ok. I am really confused what can cause that.

Somebody can help me ?

I saw some post about the same problem, but nobody never came back with the solution.

Is not my car, but it is doing the same...


Thank you

 

Replace Transmission fluid. It will help a lot, improving the fluctuation.
But be aware that it is a special procedure to do the change. I did mine at Mittler Motors in Newmarket, very professional people.
