2008 C220 CDI
Intermitent Check Engine Issue
HI MB World!.
I'm having issues with my C220 CDI 2008 and the dealer cannot tell me what it is or is hiding something.
When I run the car for several minutes beetwen 100 and 120 Kph the check engine light turn on, but nothing in the performance seems to differ and the light stays on for about 1 or 2 days.
Also randomly when staring the car in the morning: the exhaust blows dense grey smoke for several minutes but nothing appears in the dashboard.
I've borrowed a friend scanner and it tells 2 memorized events:
200C Check components B6/1(Camshaft Hall Sensor) and L5 (Crankshaft Position Sensor). Wrong Signal assignment from Crankshaft and Camshaft.
AND
200B B6/1 (Camshaft Hall Sensor) Missing signal from camshaft.
Any advice will be really apreciated. Thanks!

The smoke is likely just incomplete combustion while cold & will not be helped by the engine crank & cam sensing messing around. You almost certainly have a bad or unplugged sensor.
I find it amazing that the car is storing these codes but the dealer can't diagnose the problem with their Star.
As acr says. Tell the idiots what is wrong & tell them to sort out the sensors.

Understood. They just don't suffer the level of sensor failure that petrol models do.
