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.

There's loads of other stuff about your CEL there too.

wow very imformative, thank you, i am actually walking out the door to
a 1.8T engine specialist who said may have an extra MAF from an
previous engine, we are jsut going to switch them out, then I will
reset the light if i can, if not then just unplug battery, and drive
another 50 miles to see if it comes on, if not then hooray, i can go
take a smog test.
