One problem related to gasoline fuel system has been reported for the 2003 BMW 745. The most recently reported issues are listed below.
On several occasions my BMW 74li 2003 has registered a engine malfunction after traveling long distance at 55 miles per hour. The engine would stall on the last time the company try to state that it was the gas but that is not true, I have always used high octane per the owner's manual. I have come across several complaints regarding the 5 series and 3 series and I am sure the same problem is happening in the 7series. The BMW needs to look into this problem.
