I HAVE A 2001 BMW 540IA [XXX] AND ALL THE EXTERNAL LIGHTS ARE GRADUALLY FAILING. IN ALL CASES THE LIGHTS BULBS ARE OK. FIRST THE PASSENGER SIDE REAR TURN SIGNAL LIGHT FAILED, THEN THE DRIVERS SIDE DAYLIGHT RUNNING LIGHT, THEN THE PASSENGER SIDE REVERSING LIGHT, THEN THE PASSENGER SIDE BRAKE LIGHT, THEN DRIVERS SIDE HIGH BEAM, THEN THE DRIVERS SIDE FRONT TURN LIGHT ETC. FAILURES WERE OVER APPROXIMATELY A 2 WEEK PERIOD. THE MOST DISTURBING THING IS THE ONBOARD COMPUTER IS SHOWING ALL THE EXTERNAL LIGHTS WORKING CORRECTLY. MY BMW MECHANIC TELLS ME THE FAULT IS IN THE ONBOARD LIGHT CONTROL MODULE (LCM). I CONSIDER A FAILURE OF THIS NATURE TO BE COMPLETELY UNACCEPTABLE IN A 4 YEAR OLD VEHICLE AND A SERIOUS SAFETY DEFECT THAT HAS THE POTENTIAL TO RESULT IN AN ACCIDENT. I HAVE REPORTED THE PROBLEM TO BMW NA, SO FAR THEY ARE NOT INTERESTED IN INVESTIGATING THE PROBLEM. *NM UPDATED 07/18/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
ON CERTAIN PASSENGER VEHICLES, A MICROPROCESSOR IN THE AIR BAG CONTROL MODULE, WHICH ACTIVATES THE FRONT AIR BAGS, THE SIDE AIR BAGS, THE FRONT SEAT SAFETY BELT PRETENSIONERS, AND THE BATTERY SAFETY TERMINAL, MAY HAVE A MALFUNCTION THAT COULD LEAD TO AN UNINTENDED ACTIVATION OF ONE OR MORE OF THESE COMPONENTS.
Consequence & remedy
Consequence: UNEXPECTED DEPLOYMENT OF THE AIR BAG(S) COULD CAUSE SERIOUS INJURY IF AN OCCUPANT IS TOO CLOSE TO THE DEPLOYING AIR BAG(S). IN ADDITION, THE BATTERY SAFETY TERMINAL MAY ALSO BE ACTIVATED. IF THAT HAPPENS, THE STARTER CABLE WOULD BECOME DISCONNECTED FROM THE BATTERY, AND THE ENGINE COULD NOT BE RESTARTED.
Remedy: DEALERS WILL REPLACE THE AIR BAG CONTROL MODULE. OWNER NOTIFICATION BEGAN NOVEMBER10, 2003. OWNERS SHOULD CONTACT BMW AT 1-800-831-1117.
ON CERTAIN PASSENGER VEHICLES, THE ENGINE AUXILIARY/COOLING FAN OPERATION, INCLUDING VARIABLE SPEED, IS ELECTRONICALLY CONTROLLED. FAILURE OF THE FAN MOTOR CAN CAUSE THE ELECTRICAL CIRCUITRY OF THE FAN CONTROL UNIT TO OVERLOAD AND FAIL, CAUSING THE FAN TO STOP OPERATING.
Consequence & remedy
Consequence: IF THIS WERE TO OCCUR, ENGINE OVERHEATING AND SUBSEQUENT ENGINE DAMAGE COULD RESULT. IN ADDITION, IT IS POSSIBLE FOR THE FAILURE OF THE ELECTRICAL CIRCUITRY TO CAUSE A FIRE IN THE FAN CONTROL UNIT LOCATED IN THE FRONT OF THE ENGINE COMPARTMENT.
Remedy: DEALERS WILL REPLACE THE FAN. OWNER NOTIFICATION BEGAN SEPTEMBER 28, 2001. THIS IS A SUPPLEMENT TO A RECALL THAT BEGAN DURING SEPTEMBER 2001 (SEE RECALL CAMPAIGN 01V206). OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT BMW AT 1-800-831-1117.
