My problem is that my 525 E34 wont start immediately after a 10-15 min or more run.
When I start the car for example in the morning everything is fine. No hesitations at the start up and no problems during the drive. If for example stop the car for one minute and then try to start the engine again nothing happens. But if I wait for about 10-15 min everything is back to normal. Any ideas what the problem might be?
It is really annoying to have the engine running if I want to make small stops.

Thanks
