THIS COULD LEAD TO A SMOLDERING OF THE PUMP OR AN ENGINE COMPARTMENT OR VEHICLE FIRE.
On vehicles equipped with an 8 or 12 cylinder turbocharged engine, the circuit board for the electric water pump may overheat. This could lead to smoldering of the pump and/or an electrical fire in the engine compartment. Dealers will replace the auxiliary water pump to correct this concern.
BMW will notify owners of affected vehicles during November 2011. If you are experiencing a burning smell from under the hood, or you don't receive notification and you feel you should have, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call.
