Hello fellow forumers.

I have this W211 E Class 1,800cc kompressor problem.
When i start the car when its cold it will jerk quite a bit, rpm not stable and check engine was on. After its warm the engine was quite ok.
I ran to have it scan and it appeared the following code:

P201A-001 Wheel adaptive sensor, gear gap error mechanical malfunction [P0335]

I searched tru the net and i found that P0335 appears to be the crankshaft position sensor fault.

Can anyone here give me some advice on how to solve this ? Thanks in advance!
