There is only one way.....you car idles funny when you stop at a traffic light and your engine may sponatnenously die, also your car may not turn over and start for a couple of minutes, hours or even days, and then it starts as if nothing was ever wrong....

The dealer charged me $480 to replace this little POS

The AFM can be serviced if you are in DIY. most of the time, the vane get sticky due to the build up dust on the vanes.

To check. Just remove the air filter casing and release the hole clip. From the air filter casing, peep into the AFM. You can see the vane from there. Use a long screw driver and push the vane as far as it can go it. Release the force and see whether the vane will spring back. if it does not, you can open it up to clear the part that is touching the body of the AFM casing.

I have service my AFM and found that the ideling speed is more stable after the cleaning.

If you have an old air mass flow meter, then you will have a vane, which i doubt that this were used on e36. What i will tell you is that most of them use wahts called a hot film or wire element to measure air mass, and that element is not fixable, if the wire gets old or burn, thats it for you. You need a new one.

There are ways to test the air flow meter, get a multimeter and a bentley manual..
