BMW M6 Problems

Rubbing Noise From Rear Differential When Turning

During tight, slow speed turning, a rubbing noise can sometimes be heard from the rear of the car. This noise is likely coming from the clutches in the limited slip differential. If the noise persists, the differential fluid can be replaced with a special oil available from BMW. On higher mileage vehicles, this noise may never be eliminated unless the differential is replaced.

Drive Shaft Fractures

The drive shaft to the rear wheels may fracture due to a faulty weld during manufacturing. Dealers will inspect and replace the drive shaft as necessary free of charge to resolve the concern.

The Engine Oil Pump May Fail

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.

The Positive Battery Cable Connection in the Trunk Can Overheat

The insulated connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.

I am really enjoying my M6, with its 6 speed manual transmission...!!!!
My M6 for the most part is my favorite car of all time, and ive had over 100+ vehicles.

I thought 160 was pretty good for only using 6 of the 7 gears in the trans. I too hear a noise when i turn sharply to the right in the rear end of the car though. Reading rev...
I have experienced the exact same issue with my 07 m6. I too had the flange and lube bulletin performed without any improvement or success. I have had two dealers look at this issue and they are non responsive. I am going to have one more dealer evaluate this issue and then file a civil compliant against BMW this month. For a vehicle with an MSRP of $109000 BMW has to correct this issue or fa...
