535i 101F01 fault code
Hello everyone, 535i 2011 throws 101F01 "Airmass system plausability: calculated airmasses in the in the air intake system not plausible". It used to trigger CEL now and then, now its always on. Car runs great, just a slightly rough idle. No other fault codes whatsoever. Not great rough running values, which i assume is relevant to the fault code.changed intake manifold gasket , no effect. Any ideas? Thanks

Check for boost leaks. Can run throttle body test with ista too.

Hello and thank you for your reply. I couldnt find throttle body test in ista abl's. Found a test called Electromotive throttle actuator and found no issues. Both measuring sequences got the setpoint value of 5V (sum from both sensors) and there was an audible clicking sound from the engine compartment during the second sequence... is that the test you are reffering to?
