No, nothing warning light and any code on diagnostic. I will on the snap on verus dio and nothing trouble code :-(.
if start car and drive first five minute is everything ok after 5 min engine is stil cold temperature is on 50 maybe. If drive on the city relax speed almost without gas or want push gas pedal car start swing ( and this time of car swing,engine RPMs go up and down),but I ride with this problem long time :-( so now is this problem little bit bigger car no swing but kicking , when is engine oil hot around 80-90 temperature, car drive excellent.
sorry for my English, I still learn. And looking for right words. :)
The reason why the problem may seem worse is that the engine mount may have failed. So first check the engine mounts. There is a test that you can perform yourself but will need a helper.
Just search this "bad motor mount youcanic"
I am thinking you may have a vacuum leak. At this point I am not convinced that this is a transmission problem. The TCU would have stored a code at this point.
Another posssiblity is bad mass air flow sensor.
Have you had a Mercedes expert look at it?
Hello, so today I try engine mount test, others thinks I will do it later :).
but test show me that my left side engine mount is bad I think. If I try select R- reverse engine will ok last second on the video first is D engine lift up and after R and engine stay. So wrong is only left side, I right?
Do you have any warning lights on? Check engine light?
My recommandation would be to read the codes and see if there is a fault code stored.
Are you saying the engine RPMs go up and down at startup? It wasn't clear to me.
