fwiw, I put a close-up diagram of the MAF location here:
http://home.comcast.net/~day_trippr/...af_closeup.gif
The items shown are as follows:
1- wastegate bypass regulator valve -N75-
2- Evaporative Emissions (EVAP) purge regulator valve -N80-
3- power output stage -N122-
4- Mass Air Flow (MAF) sensor -G70-
You'll need to remove the air cleaner housing to extract the MAF. This means
you'll likely have to disconnect the above four items and pull the hoses off
the housing to remove it.

By "tool" I am referring to the diagnostic scan tool. I use VAG-COM, a
mainline dealer uses the official Audi/VW tool (1551, 1552, and others).
These tools are capable of performing adaptation cycles, coding units to
vehicles, clearing DTCs, setting readiness bits, etc, as well as diagnosing
problems.
The actual source of this particular problem can very likely be determined
with proper use of a capable scan tool. I flagged the MAF because they do
fail, more frequently than the other items on the potential list of indictees.
But I wouldn't simply replace it, because the problem may well not be the MAF.
I would let a qualified mainline service department work on this one...

Re: engine light vag 17544 02/02
from your previous diagnostic maybe i should just take it to a mechanic just
to make sure it's more than the MAF is the problem. i know its going to cost
me more money
but i have no way of checking if there's any air leaks..etc
