hi all just wondered if anyone can shed some light on my mates prob ive serched the threds for some one that mite have had the same probs but no luck, it a apy 2000 but with esp but dosnt seem to have a fuse in the car for the heldex, basickly it dosent work at and it has no faults showing, it didnt have an earth strap so one was put on and the plug at the back was clean, i was thinking controler? but wouldnt that bring up a code? it will show lo on the vagcom when the ignisihon is on then hi when the car is started, when it primes should it sound sort of like a fuel pump sounding or just a very small quiet electronic noise? (sorry about spelling im s**t i know lol)
