Report Date:
February 17, 1994
Campaign Number:
94V037000
Component:
FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM

Summary:
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.

Consequence Summary:
IF LOSS OF THROTTLE CONTROL FROM THE FROZEN THROTTLE BODY OCCURS WHILE THE VEHICLE IS IN MOTION, A VEHICLE CRASH COULD OCCUR.

Corrective Summary:
BMW DEALERS WILL REPLACE THE THROTTLE BODY HEATER WITH A MODIFIED HEATER.
