2006 BMW 530XI Exterior lighting Problems

The insulation on the internal wiring of the headlight (left and right) have fallen off the wiring leaving sections of conductor exposed creating shorts in the lighting system. This is a known problem in the BMW community (owners and BMW) since at least 2011. This is due to the use of bio-degradable wiring by BMW that breaks down prematurely. Replacement headlight assemblies (high intensity discharge Xenon) are over $1,000 each. Both halogen high beam lights are inoperable which reduces driver vision at night on suburban roadways. Re-wiring with correctly specified wiring is possible but requires specific skills and experience. This is a known problem which BMW has hoped would go away as few of their cars of this age are on the road. This risk assessment driven policy should not shield BMW from fully addressing their failures in material selection which impact safe use of their cars.

Inside headlight wiring insulation became brittle and falls off leading to potential shorts and equipment failure. Additional wiring throughout engine compart shows similar degradation and failure. Split wire housing to protect wires from engine heat also show signs of decay, exposing wires to excess heat and inducing failure of insulation. This is not a turbocharged engine and has lower engine compartment temperatures. This problem started 7-8 years ago and has gotten worse.

ALL WIRING WITHIN THE HEADLIGHT ASSEMBLY IS DETERIORATING AND EXPOSING THE BARE WIRING INTERNAL OF THE ASSEMBLY. THIS IS CAUSING ELECTRICAL SHORTING, ELECTRICAL FAULT CODES, AND OCCASIONAL PERIODS OF INOPERATIVE HEADLIGHTS WHILE DRIVING. THE WIRING ISSUE WAS FIRST NOTED BY MY MECHANIC AROUND FEBRUARY 2019. I HAVE FOUND THRU MY RESEARCH FOR REPAIRS THIS IS A VERY COMMON PROBLEM.

WHILE REPLACING PARKING LIGHT BULB I FOUND INSULATION TO BULB HOLDER FALLING OFF, LIKELY DUE TO HEAT INSIDE HEADLIGHT ASSEMBLY. GIVEN THE BRITTLE INSULATION FALLING OFF, A SHORT COULD EASILY HAVE OCCURRED. THE INNER CV JOINT ON THE RIGHT DRIVE WAS FOUND TO BE WITHOUT GREASE. WITH NO GREASE FITTING OR MEANS OF INSPECTION, THE AXLE COULD HAVE FROZEN, CAUSING STABILITY ISSUES.

THE WIRING HARNESS INSIDE THE HEADLIGHTS IS CRUMBLING AWAY CAUSING LIGHTS TO INTERMITTENTLY NOT WORK. THE WIRES SPARK WHEN THEY TOUCH TOGETHER. THIS IS A FIRE HAZARD.

ALL HEADLIGHT WIRING SHIELDING HAS DETERIORATED IN THE UNIT CAUSING A SHORTAGE. THIS IS A SAFETY ISSUE NOT ONLY DUE TO THE SHIELDING POSSIBLY CAUSING A FIRE, BUT ALSO AN ISSUE FOR SAFE DRIVING AS THE LIGHTS NO LONGER FUNCTION TO DOT REQUIREMENTS. *TR

FAILURES OF MULTIPLE WIRES/ELECTRICAL COMPONENTS IN THE TAILGATE/REAR WINDOW WIRING HARNESSES. SEARCH FOR BMW E61 TAILGATE WIRING PROBLEMS. THE FAILURES ARE CAUSED BY A POOR DESIGN WHERE THE WIRES ENTERING THE HINGE GUIDES (4) FOR THE GLASS AND TAILGATE ARE REPEATEDLY FLEXED AT A SHARP ANGLE UNTIL THE INSULATION, THEN THE COPPER WIRE BREAKS. SAFETY ISSUES - POSSIBLE ELECTRICAL SHORT CIRCUIT LEADING TO FIRES (HIGHEST LOAD IS FOR REAR DEFROSTER); LIGHTING FAILURES (REAR HIGH BRAKE LIGHT, LICENSE PLATE LAMPS AND OTHERS); REDUCED VISIBILITY DUE TO LOSS OF WIPER/WASHER/DEFROSTER; REAR GLASS LATCH OPENING WHILE UNDERWAY, POSSIBLY RESULTING IN LOSS OF CARGO OR INGRESS OF EXHAUST FUMES. THIS IS NOT AN EASILY REPAIRED PROBLEM AND HAS COST OVER $2000 SO FAR. I'M WORRIED ABOUT DRIVING THIS CAR AS IT IS THE MAIN TRANSPORTATION FOR MY CHILDREN AND THEIR FRIENDS.I DISCOVERED IT WHEN THE REMOTE LOCK/UNLOCK USING THE KEY FOBS FAILED, THE TRUNK INOPERABLE AND UNCLOSEABLE, THE RADIO STOPPED WORKING, THE LIGHTS IN THE REAR OF THE CAR STAYED ON PERMANENTLY AND I HAD TO DRIVE HOME ONE NIGHT WITH THE TRUNK WIDE OPEN BECAUSE THE WIRING HAD STOPPED WORKING AND IT COULD NOT BE CLOSED. AS I INVESTIGATED I FOUND MANY BROKEN GROUND WIRES, ALONG WITH SEVERAL OTHERS WITH BROKEN INSULATION, SOME WITH BROKEN COPPER STRANDS ETC. I HAVE ALREADY HAD THE RIGHT AND LEFT WIRE HARNESSES REPLACED AT AN INDEPENDENT DEALER FOR ABOUT $2200. THIS IS A SAFETY ISSUE AND I'M WORRIED THAT MORE WILL COME. *TR
