Hey Good Evening, just wondering if anyone knows what a healthy MAF should be reading at idle on a 2.0 TFSI, stock? Also, on the 18.2 update of the VCDS I can't find where to view fuel trims, are they supposed to be in block 032?

I'm going to be pedantic here, but the peak MAF value likely won't be found at "maximum RPM" (which I take to be either the beginning of the red zone on the tachometer or the wherever the rev limiter kicks in). It will be found at whatever RPM the engine produces peak horsepower, which is usually 500-1000 lower than "maximum".There is the full throttle/full load test others use and that is measure the MAF sensor readings at full throttle in 2/3 gear and the engine at maximum rpm. The value you get, 'should' be ~80% of the rated horsepower.
PS.. Anyone got any other ways to check the MAF sensor? _ Ideas, comments are welcome...
