2011 w204 C63 jerking and vibration travelling @ 120km/h speed
My car when driving ( changes the gears) just fine below 90 degree Celsius and after 90 degree Celsius (warmed up engine) its starts changing gears hard(slipping/hesitant/delaying).
Its like the diff kicks in late when accelerating.
Vibrations at 120km/h speed.
Anyone experienced this before, what could be the problem and what is the cure.
Thanks in advance.
