As explained in my original thread earlier today (see link below) I have been running a lean part throttle fuel trim of approx +19%. As a diagnostic test, I cleared the codes (zeroing out the learned trim values) unplugged the MAF and drove around for maybe 6-7 miles doing errands and such without the MAF's data influencing things... the car felt fine.
When I returned home, a quick check with Vag-com showed fuel trim without the MAF in the equation as -1.6%. I'm thinking this pretty much indicts the MAF. Do y'all agree?
