Engine won't start when hot

[Allybingo]

My guess would be that the hall effect sensor is in a bad shape. Starts fine when cold, runs fine, but doesn't start when the engine is warm.

One other thing, a bad ignitor module could give you the same problem. Had an old BMW that wouldn't start when warm, and a friend had the same fault on his 80Q.

And the winner is 'Floddy'
Ive just got my fualt check back and its come up with (00515 Hall Sensor G40 open circuit/Short with power) What should i buy, do i need a distributer or can i buy the sensor?

You say you marked the dizzy? There are already 2 marks on it - use these marks instead off your marks - the dizzy could be mounted in any position to the head - it is the relationship of th euoter casing to the inner part that is important/critical.

About these marks could someone explain exactly were they are so i can relighn or check that there right when i remove the throttle control 'once again' to sort this hall sensor problem.

Thanks all for your help!

wait i'm confused, is an ignition module part of the distributer ie the part thats broken the (hall sensor) ,if so yeh i'll have one but if not i'll have to try another distributer first let me me what you think becuse i could pick one up today i'm only in stretford, Whats confusing is the guy who got the fault code seems to think its easier to buy a distrbuter and leads which then would also clear up the crack in lead 3, All problems solved but probably expensive!

dissy £110+vat from audi, leads bout £50ish+vat from german n sweedish i did have a complete spare dissy for £50 I will have a scout round to night to see if i can find it, i thought the ignition module was the black box on the bulk head which has an HT lead going to the top of the dissy

I'm with you now, going by the fault code i think a dizzy would get the car running, i'l make a few calls ive seen some leads on ebay cheap as chips well they are at the moment!

Just buy a complete dist. from Audi. mine was £100 which had a metal gear on the end. The hall sender can be replaced, but the new dist. comes with new cap, rotor, sender and metal gear.
