128,650 miles

Dobbins, CA 

Fuel pump controller failed

The fuel pump controller actually failed after being exposed to gasoline from a hairline crack in the fuel pump's plastic housing. The crack might be attributed to improper torquing of the controller mounting screws. (The controllers have been removed and replaced numerous times. The plastic may have simply fatigued.)

It appeared the controller failed at the moment the 1-gallon (low fuel) warning came on. Could simply be coincidence. I was carrying a spare (used) controller unit and was able to immediately replace the failed unit.

NOTE: The National Highway Transportation Safety Administration is now investigating fuel pump leaks in the 2005-2008 R-Series BMWs. Some 24,000 vehicles may be involved.
