I have a ML230 European and 5 Emissions -Failed this year.
I already change O2 sensor, catalytic converter, spark plugs and MAF
I spend much money replacing the components and for what? I already send the car to mercedes and no one can tell me what the problem is
Value of Lambda sond > betwen 1.06 and +/- 1.15 Must be <=1.03 - Emission test failed
I think is one thing its strange When the throttle is on 4.000RPM and the car stoped the engine goes up and down. +/- 500RPM up and +/- 500RPM down. Its normal?
Could you help me please? Thank you in advance

Crankshaft Position Sensor needs to be replaced.. Had exact same problem with 04 W163. Replace Cam and Crank sensors.
