[V8] Loss of Power Saga: Finally Pulled Codes

[Torrence Thomas]

Fellow Listers:

I need your help on deciphering this one. Got the VAG-COM solution and 
pulled codes for the loss of power
problem.

This is what came back:

Skipping Address 15-Airbags

I can't even find a reference to the 00521 - CO Fuel Trim Pot. (G74) in the 
service manuals, much less have any idea what and where it is. I really 
need help on this one. Any assistance/input is truly appreciated.
