MAF, is this even possible.

Post by JayM1969 »

I stuck my mates code reader on the car and I got 2 codes
16485 p0101 mass airflow sensor implausible signal
17964 p1556 charge pressure control, negative deviation
So I removed the MAF cleaned out the filter, pretty clean to be honest and sprayed the inside with contact cleaner. It made no difference at all. then my mate said just disconnect it and try it, so I went for a run and for the 1st time in 12months the car ran like a dream, had a little smoke on start up but other than that it was a completely different car. Is that even possible ? I thought this sensor was needed to tell the ecu how much air the car was getting.
Can i order one of these from euro car parts or am i best ordering from VW ?
The second erroe code has me beaten, anyone give me any ideas ?
Thanks Jay.
