Title: Starting & Cutting Out Still
Post by: clivusdel on 30 January 2011, 12:21: help...... again please???

i have had some starting problems on my mk3 gti 8v
it will start & suddenly cut out, it does this about 3 or 4 times before it starts ok
i was advised it may be the ecu relay (no30), so i bought one and changed it
but it hasnt made any difference

any more ideas more be a great help

Post by: rubjonny on 31 January 2011, 15:34: prob easier to get us the part number off the ecu. basically i suspect theres a problem with the factory immobiliser, though usually its only on 96 cars. but if we can get part number off ecu that'll confirm it either way :)

other things it could be is damp in the dizzy cap or leads, faulty cap arm or leads, faulty coil, or maybe a dodgy crank sensor. its worth cleaning out the throttle body as well

Post by: clivusdel on 31 January 2011, 16:29: new dizzy cap & arm
new plugs
t/body & air intake all removed & cleaned out

it does have symtoms of immobilisor, but i dint think it had one?

sounds like a sensor, dose it cut out when hot and wont start until it as cooled down

it does either when first started, or if i drive up road to shop, stop it, then it does it again.
so it does hot and cold really.

or more like this (its a mk2, but mk3 is similar, isv is the metal tube thing between the rocker cover and the inlet):

Title: Re: Starting & Cutting Out Still
Post by: Sii on 06 February 2011, 14:16: Crank position sensor is my guess! If you do a search there are pages and pages on this.
Best of luck with it! :smiley:

Title: Re: Starting & Cutting Out Still
Post by: clivusdel on 07 February 2011, 18:58: are AGG & AGY fault codes?
i have no way of fault checking
what symptoms will faulty crank sensor give?

no these are not fault codes, they are engine codes. This code can be found on the white sticker that is normally in the boot of your car and stuck inside the cover of your VW service book.

Post by: clivusdel on 07 February 2011, 21:14: no service book

Post by: rubjonny on 08 February 2011, 10:12: symptoms of a faulty crank sensor are exactly what you describe in your first post, my ABF engine did exactly the same :)
