Mass Airflow Sensor

What is this? What does it do? Where is it commonly located?

If your car has one it is located between the air filter box and the
turbo, or the intake manifold. Mass Air Flow sensor. Google is your
friend.

It measures the amount of air going into the engine.

Determines the amount of air through the air filter to the air intake
mainfold. Does this by a sensor in the air flow path by moving per the
amount of air going through that path, and, delivering a (electrical)
current in reflection of that sensor movement.
Seldom breaks or degrades, leave it alone.

Although the earlier a4-platform VWs had one that did have a higher
probability of failing.

Same with the A3's. AND it was expensive as hell.
The worst thing you can do to destroy the MAF is put an aftermarket cold air
intake on it with an over oiled air filter. The oil coats the MAF which
then burns off and leaves a deposit that screws up the readings.

Chilton claims the mass airfllow sensor can cause running problems if
it's failing: stalling and idle problems

yep
I have yet to see a bad one yet, but I have heard of them. ;-)
