Hi All,

BMW f11 520d 2014

Not sure how to troubleshoot this issue to be honest, Fuse 42 keeps blowing after driving for couple of minutes.

42 30A
Electro-hydraulic engine mounting solenoids / EGR cooling bypass valve / Oil quality sensor
Oxygen sensor behind the catalytic converter / Oxygen sensor in front of the catalytic converter / Mass airflow meter
Compressor bypass / Mass airflow meter / Oil level sensor / Wastegate control solenoid

What happened is I reversed in to wooden pole at like 2-3mph with the side were exhaust is on 520d. Since then 42 fuse in glove box keeps blowing. I have lifted the car up and inspected exhaust from every possible corner including all sensors, no damage anywhere. Impact speed was near to nothing and there is only a little scratch on the car, but this must of triggered something.

any idea how i can troubleshoot this?

By any chance anyone has a wiring diagram for fuse 42?
