CEL code has been on forever it seems, I just replaced timing belt
system, water pump, turbo line hose, vacuum hose, check valve, and
front brakes and rotors.

I have a 2000 A4 1.8T Quattro, Auto tranny, 79,000 miles. Wondering if
this code which did not come on for 150 miles right after I replaced
the hoses and check valve is due to a faulty MAF sensor.

Where is this sensor located? How to i remove and install? Also, why do
Audi dealer's never want to replace this because we are given extended
warranty? So they diagnose other problems and let you pay for that so
you don't get free labor and they have to lose possibility of labor
charges.

Need help.
