Guy's,
This is my M50 525i warm starting hair puller. The car will NOT start until up to 3 attempts have been made once engine is warm. When cold, first time every time.
1) Recent advice is to pull the fuel pump (in situ within tank) and replace. AUD$800. (reluctant)
2) I've had the injectors cleaned $350. No luck there.
3) Aftermarket Immobiliser has been spoken of recently by new mechanic who claims this may be possible cause.
4) O2 sensor has ben checked and is ok.
Is there anyone out there in Bimmer land who has any ideas?
Cheers,
Chris.
