So i went through a deep puddle last wk and have been working through getting my 2013 535xi back running. it stalled and i towed it back to my house. DLed bimmerlink had a bunch of codes but main was a misfire in 3&4. Got new plugs put them in and cleared all codes. now I have a cel but only code is 102A32 air mass too low error. looked around to make sure everything was connected and didn't see anything. Any ideas on what/where to check other then just replacing the meter.
so checked everything looks/sounds connected but i am getting a funny buzz from the pipe that goes from air box to front passenger side(which i removed to do plugs 5/6)
also with bimmerlink I'm getting no reading for air mass flow HFM

Try cleaning the MAF and MAP with some MAF cleaner.

If you can clean the MAF it might be ok, but your better off replacing it if water got into it the cleaner removes the protective film on the sensor itself so it’s a one time deal cleaning
