[Icyjaws]

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
