Title: AUM ignition system?
Post by: Mrwebster on 26 September 2010, 18:30
so my aum engine running on 3 then clears when above 1000 revs,   changed all coil packs £50 each!,  changed spark plugs twice,  gave her full service at vw,  read on here about a ignition amplifier but cannot seem to find one on mine? :(
what feeds the coil packs on a 1.8t aum 2002

Checked the coil pack loom condition?

£50 each for coil packs, you were robbed!

AUM's have it all built into the coil packs there is no ignition amp. As said check the wiring:

Faulty MAF?

just comes up cylinder 3 misfire detected,  and p00300 sumthing like that
so is there a positive feed to the coil pack at all time?  reason i want to know is i had full custom stainless steel exhaust on and it backfires like a b!tch but only when you turn the key on and off loads of times,  if i was to make a simple on off kill switch i could make it pop bang spit flames on demand without having steering lock come on? thanks
