Just looking for guidance before I buy a new MAF.Ĭar: 2001 VW Polo 1.4 TDI 6n2 AMF PD Engine on 155k miles. Othertimes it reads 539mg/str which I think is a dummy number when the ECU is getting a Implausible Signal.Īm I right thinking this issue would ether have to be a faulty MAF or a leak after the MAF but before the Turbo? I took the car for a good blast and logged some stats in VCDS, What doesn't seem right is at idle it can draw about 162mg/str of air according to the MAF but then at say 2000rpm it says its using less air at 147mg/str, even when I was flooring it at about 3000rpm in 3rd it was pulling up a hill great and boost showed about 2300mbar, yet the MAF said it was using the same 162mg/str of air?. The car seems to run perfectly as ever though which confuses me, I have tried to clean the maf with maf cleaner but it didn't clear the error. Not meant for V6 TDI or gasoline 2.0 turbo engines. I was doing a routine check with VCDS after I fitted a new coolant temp sender this week, and noticed this error.ġ6485 - Mass Air Flow Sensor (G70): Implausible Signal.
