ayr flow senser
just after your Airfilter
Weak fuel pump? Bad fuel filter? Bad air filter? Plugged catalytic converter? I had the same problem with my Corsa, changing my mass air flow meter fixed it!!

If this is the Eco Tech Vauxhall Engine then it will either be the EGR Valve (Exhaust Gas Recirculation Valve) or the Mass Air Flow Meter. It's worth disconnecting the Mass Air Flow Meter when it is reving and see if this alters the revs if not then I would suggest cleaning the EGR Valve as they get clogged up with black soot and subsequently alters the air to fuel mixture as would the Mass Air Flow!
the mass air flow sensor detects the flowing of mass air into the engine while the mass air flow meter detects the amount of mass air flowing into the ingine.
i think it's in the mass air flow meter == == If you meant the Intake Air Temperature (IAT) sensor, it is either built into the Mass air flow sensor, as suggested above, or a separate sensor in the induction air piping not far from it.
To calibrate a mass flow meter, first ensure that the meter is installed correctly and that the system is free from flow disturbances. Then, use a calibrated reference flow meter to compare the readings of the mass flow meter at various flow rates across its operational range. Adjust the flow meter's settings or coefficients based on the discrepancies observed during testing. Finally, document the calibration results and repeat the process periodically to maintain accuracy.
There are no major disadvantages of thermal mass flow meter as compared to its advantages. But cons of thermal mass flow meter includes: Not effective in Vibrations and turbulence You should install flow straightener with flow meter Periodic cleaning needed
"PBT-GF30" simply means "PolyButylene Terephthalate with 30% Glass Fibre", the plastic used in all air mass meter housings - regardless of make! Look UNDERNEATH for the actual part number! (Not a very helpful design ...)
Please refer to the answer as below
no its not. idlecontrol valve controls idle mass meter measures air flow into itake
The mass air flow meter for a Passat 1.8T can vary depending on the year of the vehicle. It is recommended to check with a Volkswagen dealership or a reputable auto parts store to ensure you get the correct part number for your specific model and year.
