Got petrol?.

I take it you fitted new crank sensor

[Kmad]

No    but it was driving for 10 days now with no problems???

[dixie180]

Ok.I could be barking up the wrong tree but i would definitely get it changed mate.Like i said a VAGCOM may not always throw up a fault with the crank sensor.

[Kmad]

I know embarrassed  now will change it asap .... Its confusing me because it was driving for days now with no problems and never cut out while driving.

Just PM'd you bud.

Hahaha finaly i got it it was dodgy fuel pump relays !!! f**kin 3 of them ,i should play the lotto with the luck i have.... I started notecing that when they heat up and i turn the car off it wont start again so i started swapping them every time it happened and car started straight away with the cold relay.... It took me long time to figure it out because i was doing only short runs to work and back so it never heated properly...strange thing is that the relay was clicking and the voltage at the pump socket was correct but every time the relay was electricaly loaded with pump drowing  current from it it would fail  Guys thanks for all the help specially Dixie hopefully it stays going
