Starting Issues - 4.8is
I have a 2005 X5 4.8is with about 71k miles now and have had some difficulty starting it. It starts fine first thing in the morning, but after I have driven the car and let it sit for 1 to 2 hours and come back to start it, the starter will run for 15-20 seconds before it actually starts.
Again, no starting issues when the car has sat overnight, but once it gets driven and is left for a couple hours, that's when I have trouble starting it. The starter sounds like it is running very strong. I have scanned the entire car twice now using a GT1 scanner and there have not been any codes at all. Help! :( |

Forgot to mention that I actually replaced the ignition switch two days ago and the problem persists......

When my battery was going bad, I had a several episodes of cranking and not starting instantly - however it was never 15 - 20 secs. It was more like 2 more secs.
Simple to have the battery checked just in case though. I guess it could be several things - maybe coil, fuel injector? Wonder if one of the sensors like MAF or oxygen could cause this? Sorry, not being much help am I. :( |

Any other ideas? I am about to throw a new fuel filter on. Probably not the culprit, but it has never been replaced and figured it would be a good idea....

May be you have a leaking injector(s).
Next time, while cranking, try to floor the gas pedal to force the DME into 'flood clear' mode to see if it makes a difference. |
U should scan with gt1. That will let u know if it's as easy as a faulty gas cap. That was my prob
