a3 1.6 not starting after getting warm

[baker_boy]

right when i go out 1st thing in the morning the car will start fine and when i come out of work later on, roughly 8hrs later it will start up fine, but when i stop for petrol or to go into the shops after it gets warm it wont start properly..
the starter motor would engange the engine and turns it a little bit but then it just jumps out again, it will sometimes take like 5+ times of me turning the ignition off and trying to start it will it actually start, anyone got any ideas what it could be? thought it might have been the immobiliser being dicky but i thought that it wouldnt even try an attmept to start it... possible new starter motor needed??

any help is much appreciated

cheers

first get a VCDS scan

No Start – Battery - ECU, Fuel Pump Relay, Ground

My guess is the Crank sensor, which is failing. Had the same issue, would start when cold, but when hot problems started

Sounds almost exactly like the issue I was having only the other day!

Does the ASR (Traction Control) light come on?

finesse - thanks for the info theres a guy local to me in bedford which shows on that map so will see if i can get hold of him

johnone - i read your post earlier actually and thought it could be the same problem, but my car drives around fine when it is going and the asr light doesnt come on.. it could still be the crankshaft sensor though, not sure whether to just change it and see what happens, but rather someone just saying it could be that id like to find out myself if you know what i mean, but the thing is i dont have this vagcom thing so i got no way of checking it out.. btw was your car slightly misfiring at all on idle? before you changed the sensor of course..
