What car? surely it needs the AFM to run full stop otherwise it doesnt know how much air is flowing into the engine? (if on std management i guess??)

the pipe is on, but the wrong way round, if you look on the pic it has clips on one end of the pipe, this side connects to the airbox, i have it currently connected onto the pipe to the inlet

if it put it back round the correct way as it should be the car struggles and hesistates and wont go past 4.5k revs, when the pipe is on the wrong way round car pulls very very hard BUT idles a bit lumpy?

Then sounds like you need a new one

Have you tried cleaning it?
Spraying carb cleaner through it while reving sorted the problem I had with mine for a short time but then I had to replace it...

Some vag TDI owner take their AFM off. Then on the electrical connector they bridge the terminals with a resistor.

Result, ecu thinks engine is getting max air all the time and fuels like a badger.

You can't run a car without an AFM. If you unplug it, the ECU throws up an EML and replaced the sensor values with "guessed" values, to make the car driveable.

My guess would be it's dangerous the wrong way round, overfueling, rich mixture gunna burn something out?
