This is the fault code i get when i Scan with VagCom.

Possible Symptoms 
Bad Fuel Economy 
Possible Causes 


Air Leak between Mass Air Flow (MAF) Sensor and Engine 
Injector(s) faulty 
Fuel Pressure Regulator faulty 
Throttle Body faulty 
Intake Air Filter dirty 


Possible Solutions 
Perform Throttle Body Adaptation 
Check Hoses and Pipes to/between Components 
Check Intake Air Filter 
Check Fuel Pressure Regulator 
Check Exhaust Gas Recirculation (EGR) Valve 
Check Injector(s)

when i gear down the revs drop to about 300 revs. unless i blip the throttle at the right time the car dies.

ive had the crankcase breather pipe, and air filter replaced. when the breather pipe was replaced it made the problem a hell of a lot worse. cuts out about 10 times on a 10 minute drive

Has anyone here had experience with them

Mr.David

Sounds like it could be that the MAF is knackered?

I would'nt go buying maf's just yet. Get a smoke test done to ensure there are no air leaks.If every thing is okay(which I guess is not)then they can readapt the throttle body.

Faulty Idle control valve?

is there any way of readapting the throttle without bring it to a garage?

strapped for cash. if i wasnt id just go to the dealer and let them do whatever they want

when i disconnect the MAF it gets a lot worse.also, it shows no faults for the MAF so a few people have said its very unlikely to be faulty

Have you tried cleaning the throttle body (or is this what they mean by adapting)? I had a similar problem of revs dropping (non Audi) and it worked wonders. Done it myself in-situ with a can of carb cleaner, lint-free cloth and cotton buds.

i say you still have an air leak from the positive crankcase ventalation (PCV) pipes. they are made of hard plastic and crack with age. replace them all, even the one that connects to the bottom of the engine block.
