My 8V was suffering from two annoying, niggling faults for the last couple of months that I just could not live with any longer.....firstly when I would try and start the car it wouldn't fire up and then when you turned the ckey back to 'off' it suddenly fired up. Then on some occasions when decelerating and the clutch was dipped the engine would cut out.
The AA came out and suggested new HT leads, distributor cap and rotor arm which initially seemed to work. However, the fault hadn't really gone away so despite this being a 'nice to know' they won't go again kind of fix the problem remained.
Anyway, to cut a long story short my ever dependable VDub specialist spent a couple of hours diagnosing the problem (no fault code on VAGcom) it turns out that the throttle body was blocked. Apparatly there is what he referred to as a 'butterfly' inside that moderates the air flow and this was bunged up hence the lack of flow.
So to save you all wasting time and money and diagnosis try this first...the engine (it has only covered 55k) feels like new once more and my cursing and promises to sell the 'heap of sh*t' have now passed :grin:

most Vw's suffer from dirty throttle bodies and I advise a clean up once a year, It's part of my annual service regime and has being on my last 5 vw's :smiley:
(easy on the mk3 golf, not so easy on the 1.8t's etc as you may need vag-com to reset it)
