Answer 1
I'd get the ignition switch checked and the wiring harness for rodent damage. You really need someone who can diagnose your car properly. Try to find a VW specialty shop. Looks like someone just doing a guess work. Zee -
Comment 1
i took it to a specialist and he replaced my coil, could the crankshaft or engine speed sensor cause symptoms like that -
Comment 2
Yes and they can be properly checked with a lab scope. Also loose electrical connections, oxidation on electrical pins could cause this. Zee -
Comment 3
this morning when it died i pulled a plug wire out and tested for spark and it didnt have it at that time does that help narrow anything down -
Comment 4
Not really, all the above failure could cut off the ignition. Did your tech checked or changed relays? Zee -
Comment 5
they said they did, but im very sceptical -

you sound like a great mechanic id love to take my car to you...i just got it back again from the shop and this time we changed the crank sensor ie engine speed sensor and ive driven it 60 miles and nuthn so far so my fingers are crossed could it possibly be a $140 part after spending almost $3000 on the darn thing... -

This is why a small diagnostic fee could save you thousands of dollar. Of course it has to be performed by a competent technician. I keep telling people to get a proper diagnostic before they start to replacing parts. A code reading isn't one. There are many good tech (not just part changers) are out there, you just need to find one and stuck with him. Zee -

Answer 2
