You can probably see from my name i own a mk3 golf cabrio. caused me a few problems, none too hard to sort out except this recent one, had dizzy changed as garage suspected a hall sensor problem (£120!) and as I expected this didn't fix the problem as the car was sound WHEN it ran, and is still is fine, WHEN it starts. after lots of reading other peoples problems and a few helpful emails i was right to begin with in thinking it was an electrical/immobiliser fault. now the problem. I'm skint. is there a way to just bypass the ignition decoder thing around the ignition barrel. its not the key transponder by the way, I have tried another key provided with the car. the problem is intermittant but seems to be getting worse, it always starts but not for long (2 secs max) you can rev it, push it, tow it if you wanted i suppose but it wont go! in the summer i wouldn't mind sitting there half hour listening to it die over and over but in the winter its getting pretty old pretty quick.
