I'm having trouble with the Mercedes-Benz W213 and the code P0101FA.
Icarsoft v2.0 has been used to modify the hfm settings, and I have also changed the air filter and mass airflow meter. When the engine rpm reaches 2.5–3,000, the car enters what seems like a limp mode with limited power.
My car went into limp mode and my CEL disappeared for almost three weeks. And I'm finally back. My observation during the MAF re-adaptation process (Hfm drift values xxxxx) was that Every one of the current correction values is zero. Could this be the correct version? As far as I recall, when there was no limp or CEL, they were all about 10 years old.
With a functional maf, shouldn't the correction values be set to 0%?
Does anybody else have this problem?
The OM642 P0101FA is in limp mode and has reduced power as of W213 2019.

boost leak is the most typical cause. The meaning of P0214fA14627 is unclear to me.

There is a problem with Air Mass Meter 1, P0101FA.

Make sure to inspect the MAF wires as well as any potential boost leaks; a hose split can be difficult to spot.

Can you tell me the recommended voltage for the MAF pins?
