1991 BMW 525

Report Date:
April 11, 1994
Campaign Number:
94V066000
Component:
FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

Summary:
FEED FUEL HOSES CAN HARDEN AND "SET" OVER TIME, ALLOWING A SEEPAGE OF FUEL AT THE CONNECTION BETWEEN THE HOSE AND THE ENGINE FITTING. THE CLAMP USED TO HOLD THE HOSE TO THE FITTING IS UNABLE TO COMPENSATE FOR THE HARDENING OF THE FEED FUEL HOSE.

Consequence Summary:
FUEL SEEPAGE BETWEEN THE FEED FUEL HOSE AND THE ENGINE FITTING CAN RESULT IN FREE FUEL IN THE ENGINE COMPARTMENT, WHICH COULD RESULT IN A FIRE WHEN EXPOSED TO A SOURCE OF IGNITION.

Corrective Summary:
A REDESIGNED FEED FUEL HOSE AND HOSE CLAMP WILL BE INSTALLED TO ALLEVIATE THE FUEL SEEPAGE.

1991 BMW 525

Report Date:
February 15, 1991
Campaign Number:
91V029000
Component:
VEHICLE SPEED CONTROL

Summary:
INSUFFICIENT AXIAL CLEARANCE EXISTS FOR THROTTLE VALVE, SHAFT, AND HOUSING DUE TO THE DIFFERENT THERMAL EXPANSION RATES OF THE SEPARATE PARTS WHEN VEHICLE REACHES NORMAL OPERATING TEMPERATURES AND AMBIENT TEMPERATURE IS 40 DEGREES FAHRENHEIT OR LESS.

Consequence Summary:
THE LIMITED AXIAL CLEARANCE CAN CAUSE THE MOVEMENT OF THETHROTTLE VALVE TO BE IMPEDED, THE VALVE IS UNABLE TO CLOSE. THIS IMPEDANCE WOULDKEEP THE VEHICLE FROM DECELERATING AT THE USUAL RATE AFTER THE GAS PEDAL ISRELEASED; THIS COULD CAUSE UNEXPECTED MAINTENANCE OF SPEED AND AN ACCIDENT.

Corrective Summary:
INSPECT AND REPAIR THE VEHICLE BY REPLACING THROTTLE HOUSING IF INSUFFICIENT AXIAL CLEARANCE IS FOUND.
