Hi bros,

Recently I was driving my W204 and the dreaded yellow color engine light color came on.

Brought it to friend who had those diagnostic device and he checked it for me. The error messages shown is as follows;

1. ECM ENGINE CONTROL MODULE (MED40 for combustion engine M274 (N3/N10)

2. Position of the exhaust camshaft(cylinder bank 1) is implausible relative to the position of the crankshaft. Stored there is a signal above the permissible limit value

3. Cylinder 1 above knock/combustion vibration sensor threshold signal rate of change above threshold

Any bros encountered the messages before and is it a serious error? Much thanks in advance guys!

If you don't mind helping a bro out pls Whatsapp me at 94888166 thanks!!

Hi Mikhail,

Looks like your Camshaft Position Sensor (Crank shaft sensor) is faulty.

Thanks a lot bro! Is it a very serious thing or is this a normal wear and tear. Pardon my ignorance, really noob here
