This model don't use air mass sensor, only pressure sensors. The car act normal after clearing fault code, only reappear after few days. Are these fault code anything to do with primary oxygen sensor ?
Thanks.

there is also the case of o2sensor
I think to be in a different place.
There is a case in which you issue this code in misfire
Also requires inspection of the plug-and-coil:fuel regulator

i think that is best way is following the producer on xentry
RE: W212 Check engine lamp - kevinx - 16-09-2015
Did the costumer come back yet? Did you check fuel pressure. How about the injector on cyl 1. Injector leaking or spraying too much fuel? Did you follow what Xentry said to do?
RE: W212 Check engine lamp - malguy - 17-09-2015
The owner haven't turn up. Xentry don't give any clue
I will report once have update.
Thanks.
