I'm working on a 2012 Mini cooper S.
It had a lot of codes for airbags and engine problems. I fix everything, except a hard code 2b51 (Air Mass Sendor Signal)

I replaced the airflow meter, checked wires from MAF connector to ECU... there is wire continuity.

After clearing codes, at just 2 on/off cycles the check engine light is back ON.

DATA STREAM

Air mass, hot film air mass sensor : 1086.80 KG/H
Engine Speed : 685 RPM
Intake pipe vacuum 960.94 hpa


Any ideas??

Thanks!!
