    hi really need some help with this one. just bought a 2002 a4 2.0 fsi estate private. ever since i have had it there has been a problem when at idle it misfires and idles very badly. it never stalls but you can feel the whole car shaking. the engine runs like a dream when on the go but is plauged with the idle problem which does not happen all the time but usually when re starting the car when warmed up, sometimes just when it wants at traffic lights and very occasionally from cold, but this is rare. it will idle badly for a few seconds to a few minutes but usually always goes away and gets back to idling normally.
    in addition when on the move the car occasionally hunches at around 2000 revs in any gear and makes a slight pinking noise this is quite rare but does happen.
    looking through the service history the car has had poor running issues for the past 3-4 years as the car seems to have had new plugs,maf sensor, genuine vag coil packs, throttle body cleaned etc.. virtually every year.
    i have just spent a fortune at 2 audi specialists who have replaced the whole manifold intake,fuel rail, all coil packs, plugs (irridium) and bosch maf sensor. they have tested for oil leaks and timing but all is perfect. this was confirmed by another garage who also did the same tests. i have now spent £1800 on the car and no garage seems to be able to fix the problem.
    please does any tech or expert have any ideas! the only options the garage have given me are the ecu might be faulty or a mate suggested an engine flush as there could be a sticking valve. any thoughts would be appreciated
    thanks

    Hi,

    Have you tried running it on Shell V-Power? I remember reading somewhere that fsi engines run better on it as they are very sensitive to fuel quality. Worth a try?

    Hope this helps, good luck!

    Presumably there are no fault codes stored and I expect the engine is an AWA?

    hi engine is 2.0 fsi AWA non turbo engine, each time the car is plugged in it shows misfires on cylinders 2 and 4 but no garage can say why, plugs and coil packs are all vag and new, looking at the service history this car has had this problem a while as the last three owners have all changed coil packs, plugs, maf sensor, knox sensor, throttle body and on the garge receipts it always says 'to investigate poor running idling' the last garage checked for air leaks and timing problems but non were present. the car always shows a misfire whenever plugged in to the computer. it's strange as the car can run perfectly for hours but will then suddenly start to idle really badly. it almost always badly idleswhen you start it up once warm, but hardly ever when cold.

    If it has misfires logged, these need tracing.

    thats the problem, 3 audi specialists can't say where the misfires are coming from and have replaced virtually all the parts that could cause the misfires. when plugged in to the vag computer that does not specify where the misfires originate from, it just logs a misfire. the car never misfires when driving, just at idle.

    If they know what they are doing, all they have to do is look at the misfire logs in Measuring blocks (groups 13-15 ish) and the misfiring cylinders are shown even down to individual misfires.
