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
