Diesel Fuel Heater May Turn On and Stay On
Engine, August 18, 2011
RepairPal Expert Overview
Our Quick Take:
The diesel fuel heater could turn on and stay on, resulting in a dead battery and/or the unit overheating.
What Should You Do?
BMW will notify owners of affected vehicles beginning in October, 2011. You may not experience any symptoms. If you don't receive notification and feel you should have, or you are experiencing a dead battery condition, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call.
The diesel fuel filter heater, which is used to warm the fuel at low temperatures, could experience an electrical overload condition and become permanently activated. The heater could remain active even when the ignition is off, which can lead to a dead battery. The unit itself could also overheat, increasing the risk of a fire. Dealers will replace the fuel filter heater to correct this concern.
