1) Open the hood.
2) Locate the air filter box on the starboard side.
3) Locate the flexible hose between the airbox and the intake plenum. It's 
a 3-4" diameter hose it's pretty difficult to miss... ;-)
4) The MAF sensor is located on the aluminum "pipe/flange" thing between 
the airbox and the flexible hose. It's a black kinda rectangular gizmo 
about 1/4" thick and maybe 1.5"x2" or so with a 3-pin connector. It faces 
forward and toward the engine.
5) Undo the two screws holding the sensor onto the aluminum housing. On my 
car it was two philips/slot combo screws. On some cars I understand it's a 
T-25 with security dimple. Take the sensor out and wipe off the mating 

When you clean it, be really, really careful not to damage the two wires on 
the sensor. I understand the sensor is fairly spendy (even by Audi 
standards) so you really don't wanna break them wires...
