Defect
Certain 550I, 650I cabriolet, 650I coupe, and X5 vehicles equipped with a V8 engine, operated in conditions of below-freezing temperatures combined with low humidity, may suffer an electrostatic discharge at the fuel rails. If this were to occur, the engine's Electronic Control Unit (ECU) could be affected such that engine stalling could result. If the engine were to stall, this would result in a loss of power steering. Loss of power steering could lead to a condition in which vehicle handling and control were impaired.
Safety Risk
No risk description available.
Remedy
Dealers will install two additional ground cable between the fuel rails and the ground connection of the ignition coils.
