CelestialSeeker Posted yesterday at 12:17 PM Share Posted yesterday at 12:17 PM P0101FA on a Mercedes-Benz W213 is giving me a hard time. The mass airflow meter and air filter have been changed, and the hfm values have been adjusted using Icarsoft v2.0. After reaching 2.5–3,000 rpm, the car continues to operate in what seems like a limp mode with limited power. Just like that, CEL disappeared for around three weeks, and the vehicle went into limp mode. I returned just now. The re-adaptation of the MAF (Hfm drift values xxxxx) caught my attention. At this time, all of the corrected values are zero. Is this the way it ought to be? In the absence of a limp or CEL, I recall that they were all about 10 years old. With a functional maf, shouldn't the correction values be set to 0%? Has anyone else encountered this problem? Quote Link to comment Share on other sites More sharing options...

ENVIOclev Posted yesterday at 12:18 PM Share Posted yesterday at 12:18 PM Make sure to inspect the MAF wires as well as any potential boost leaks; a hose split can potentially be difficult to spot. Quote Link to comment Share on other sites More sharing options...
