CEL's

The Chaddening · 06-24-2019, 08:49 PM

Driving home from work and got a CEL. Had the battery replaced and coded at a local bmw dealership about a month ago.

Codes:

36BE - Engine ECU, Encoding variant not found

28A0 - Throttle valve opening angle Absolute pressure intake pipe, comparison pressure to high

2774 - Air mass, Plausibility air mass too high

Any help is appreciated.

Check maf sensor, clean it with special spray. See if there any leaks after the maf sensor.

Any particular spray you would recommend?

Is this the process you are referring to?
