The problem
THE ADHESIVE MATERIAL OF THE TWO PIECE THROTTLE BODY HEATER MIGRATES INTO THE CIRCULATION CHAMBER CAUSING BUILD UP OF IMPURITIES AND RESTRICTION OF FLOW WITHIN THE CHAMBER. THIS CONDITION AND WATER VAPORS FROM THE CRANK THAT FREEZES AT LOW AMBIENT AIR TEMPERATURES PREVENTS THE THROTTLE PLATE FROM CLOSING AS THE DRIVER RELEASES THE GAS PEDAL, CAUSING LOSS OF THROTTLE CONTROL.
Risk
IF LOSS OF THROTTLE CONTROL FROM THE FROZEN THROTTLE BODY OCCURS WHILE THE VEHICLE IS IN MOTION, A VEHICLE CRASH COULD OCCUR.
What owners should do
BMW DEALERS WILL REPLACE THE THROTTLE BODY HEATER WITH A MODIFIED HEATER.
