hello.
I am having serious problem with my car mercedes c220cdi (w204) NEED HELP PLEASE.
car start and drive very well when its cold then after more than 1 hour drive its misfire or hesitating even turn off while driving.
but when the engine goes off when i start it does start normal.

I had the car diagnose several times and its come up with (oil temperature sensor ) which I replaced but fault still here and again on diagnostic it kept coming on (oil temperature sensor)
Now I am randomly changing parts which I replace Crankshaf sensor and Camshaft sensor but fault still happening.

Note that this fault is happening only after driving more than 1 hour OR if I leave the car on idle 1 hr 30mins.

please help.
thanks
