Help! I have been having vibrations in the car for about 1 month now. These are noticeable at approx. 3000U/min, at 3500U/min these stop and come back from approx. 5000U/min. From the feeling it is as if something is vibrating or “drumbling”. The stupid is only that these vibrations are more to be heard in the interior as well as outside…(you feel these best when you drive yourself: it is as if the seat (popometer) and the steering wheel vibrates!) To the info: – Vibrating is NOT when you drive z B while driving only lets the car roll (without engine power / clutch kicked) – this vibration occurs even when you give gas in the stand! Have already checked with a friend (he has a free workshop) mE according to EVERYTHING: exhaust alignment, heat plates on the exhaust, engine storage etc. The familiar asked me now if the 225 engine has “engine compensation shafts”?! He said that in case of a defect on these waves such vibrations can arise. Any other idea where the vibrating could come from?
