Greetings all. So, problem is as follows:

Car shudders (gearbox direction) when accelerate hard (wot) in 1st, 2nd and 3rd gear. Also it does the same from 1st up very steep hill.

It started after DMF/clutch change, 3 days after it was replaced. It is original Sachs set. If I accelerate gently, there is no shudder.

My mechanic thinks it is faulty DMF/clutch set. He also said that inner CV is good. It shudder sometimes of accelerating hard on bumpy road or turning with acceleration (that is why I think it could be CV).

Does anyone has same or simmilar problem? How to test clutch? Is it contaminated with greasy fingers or coolant? ( I did have some minor coolant leak on temperature sensor, right above clutch, but I do not see a way for coolant to get in the bell housing).

If it is contamination, can I slip it a little bit to grind it off?
