The Engine Oil Pump May Fail
Engine, September 28, 2012
RepairPal Expert Overview
Our Quick Take:
On certain 2013 M series vehicles, the oil pump can fail, causing a loss of oil pressure and in some cases, the engine to stall.
What Should You Do?
BMW will notify owners of affected vehicles during October of 2012. If you experience abnormal noise from the engine, the low oil pressure warning system is active, 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) handy when you call.
Due to a manufacturing process error, the oil pump driveshaft could separate from the pump rotor. Separation of the pump's rotor could lead to a sudden loss of oil pressure causing the possibility of complete engine failure, resulting in an engine stall-like condition, increasing the risk of a vehicle crash. Dealers will replace the engine oil pump to correct this concern.

BMW is recalling certain model year 2013 M5, M6 Coupe, and M6 Convertible vehicles, manufactured from July 19, 2012, through September 11, 2012. Due to a manufacturing process error, the tolerance between the engine oil pump's drive shaft and the pump's rotor was not within specification. As a result, the pump's driveshaft could separate from the rotor.
Separation of the pump's driveshaft from the rotor could lead to a sudden loss of oil pressure causing the possibility of complete engine failure, resulting in an engine stall-like condition, increasing the risk of a vehicle crash.
