Question Details

Hi guys, I have a W211 with a OM271 engine. The air flow sensor does not work. I have changed about 3 different AFM both used and New. Still not working. I have checkd the wiring of the air flow and the wires are ok. Could the issue be in the ECU? kindly advise as soon as possible.

Also do you get any live data from the sensor?

Do you have any update on this problem? Check for any major leaks on the intake manifold.
