Hi guys.

Driving my golf to work this morning I noticed it got a little lumpy then a min later the revs dropped and it cut out. It now won't start. I'm now at work so I cant check for codes. Would anyone have an idea off the top of their heads what it might be? It still turns over but wont take.

Much appreciated

ignition module?.

Any idea of the easiest way to test if thats the problem?

[Dalo Harkin]

check the basics first, fuelling, spark etc
when you say turns over do you mean it just sounds like its cranking or does it fire up?
if just cranking then its most likely fuelling or ignition so plugs (ignition amp if it has one) etc

What engine code is it. If agu i will say ignition amp too. But cant really know until u scan it mate

[asboGTI]

looking at his sig can just about make out its a t reg so porbs an AGU

[thatwillis]

Thanks for your help. Yeah its an AGU. How easy is the ignition amp to change? Expensive part?

I'll scan it when I get back from work. Whats the code likely to say if it is the ignition amp?

it`s piss easy to change, its bolted to the side of your airbox with 2 10mm (iirc) bolts and two plugs clipped onto it.
not sure if a new one will come with heat transfer compound but you can get that from maplins cheaply..
