Do a search on the forum as these issues have been discussed a fair few times mate.

Vagcom doesn't throw any codes so Audi keep changing what seem to be the most expensive parts and hopeing for the best! It's costing me a fortune!

I've done a search, but all the threads i have found have people changing the same as me and ressolving the issue!

would an air leak on the intake side cause this?

Starter motor was another one & tbh air leak would have to be fairly vast to stop it starting IMHO to cause this.

Can the crank on the starter motor deteriorate when the car is warm? just a bit funny that it starts first time when cold... Anybody know how much a start is (ball park)?

Thanks
