Hi to all .......
I have a problem with my 2013 e class 250 , error code P0101 says mass air flow ? It’s revs at around 3,000 rpm before it’ll change gear ? Any suggestions please .
I'm no expert but a quick search threw up the following info:
The most common causes of the P0101 error code include a dirty or clogged air filter, a cracked or damaged air intake, or even the MAF sensor itself being contaminated or damaged. All of these factors would cause your Mercedes’ system to take incorrect or unexpected sensor readings that would alert the car’s systems to the issues with your car, resulting in the P0101 diagnostics trouble code (DTC).
Symptoms of a bad MAF sensor
There are a number of signs that there might be problems with your Mercedes' MAF sensor. These include loss of engine power, bad gear shifting - changing gears only at high RPM, the engine stalling after starting, hesitation and jerking during acceleration, the engine hiccuping, or excessively rich or lean idling.
