Air mass too low code 002775 on N55

humbertob · 01-13-2016, 10:22 PM

My 2011 335i has developed a tapping sound in the air filter area 2 days ago, I just scanned the car using Carly for BMW and code 002775 came up: FAULT: Air Mass Plausibility: Air mass too low ! Anybody know what do I need to replace or fix ? Car is running well and CEL is off ! Any clues ?

Just found the tapping noise source, under the air filter box is the TANK VENT CONTROL VALVE, the valve is the one that is making the tapping noise and because the tank control valve is practically touching the air box always the noise appears to be inside the air box. I just disconnected the electrical connector from the TANK VENT CONTROL VALVE and the tapping noise is gone, so definitely the noise is being produced by this valve. I think the valve is faulty ! Any advice ?

What ever happened with this? I have similar issues.

Just replaced the tank vent control valve and the issue was gone, almost a year and haven't heard the noise.

Apologies, i know it's been awhile. But the Tank Control Valve you referenced under neath - is that the Fuel Tank Control valve? Apologies and thanks
