All modern vehicles use some type of power assist for the braking system. The 8 cylinder models being recalled use a vacuum pump, connected to the power booster by a vacuum hose, to provide the necessary assist. The vacuum pump may leak a small amount of lubricating oil into the vacuum hose and this contamination could result in a loss of power assist, leading to increased stopping distances. Dealers will correct this concern by replacing the brake vacuum line with an improved version.

The Brake System Power Assist May Fail
Potential Loss of Power Steering Assist
RepairPal Expert Overview:
The engine drive belt has a device called an idler pulley that helps to keep the belt properly aligned with the power steering pump. The bolt that secures the idler pulley may come loose, causing the drive belt to fall off and power steering assist will be lost. If this occurs, you will still be able to steer your vehicle, it will just take much more effort. Your BMW dealer will replace and properly tighten the idler pulley bolt.
Diesel Fuel Heater May Turn On and Stay On
RepairPal Expert Overview:
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.
Rear Brake Failure Possible
RepairPal Expert Overview:
The rear disc brake rotors may not have been manufactured to the proper specifications and in extreme cases, one or both rotors may break resulting in a loss of braking ability at that wheel, increasing stoping distances and the risk of a crash. Dealers will inspect the rear brake discs and replace them as necessary.
