Try Jmac, he has a few motors about his place.

PS if you have a missfire, it's more likely to be the ignition amp in the airbox or a duff plug in my experience.

Thanks dude. I'll send him a message.
Racq came out and was definitely a coilpack. (he had a coil pack tester)
Plugs are no more than 10k old and they're platinum plugs. Should last longer than that.
I thought it was the ignition module. Hmmm.
I need to buy vagcom
Anyone wanna sell one?? Haha

It wouldn't tell you anything. Disconnect the bad coil pack, at tickover, then swap it with another and try again. If the amp has gone it'll be the same cylinder effected. If the coil pack has gone the miss will move.

I am still leaning towards the amp from personal experience.

problem is i dont have a coil tester like he did (it'd just run the same as it is and move cylinders without me knowing haha), hmm should i do the ignition module before the coil pack?!!?!

If you have a bad coilpack and disconnect it the engine note won't change. For example lets pick #4. You swap coilpacks 1 and 4 around then run it again. This time disconnecting the new #4 cause the engine note to change. Proving coilpack in #1 to have been the problem.

If disconnecting the new #4 made no difference the fault must be further up the line, ie the amplifier.
