2004 BMW 3 SERIES Electrical System Problems

VEHICLE ADAPTIVE XENON HEADLIGHT WIRING IS FAULTY . WIRE INSULATION IS CRACKING/DETERIORATING AND ENTIRE WIRES ARE BREAKING APART. SYMPTOMS START WITH FLICKERING XENON HEADLIGHT EVENTUALLY (ABOUT A WEEK LATER) STOPS WORKING AT ALL. VEHICLE IS MOVING OR STATIONARY, ENGINE ON. THE FAULTY WIRES ARE IN A WEATHER SEALED COMPARTMENT OF THE HEADLIGHT AND HAVE NEVER (TO MY KNOWLEDGE) EVEN BEEN UNSEALED/ACCESSED SINCE LEAVING THE FACTORY. THE ISSUE IS ON THE PASSENGER SIDE, UNKNOWN IF IT IS ON THE DRIVER SIDE AS WELL. THE ATTACHED PHOTO SHOWS BACK SIDE OF THE HEADLIGHT HOUSING LOOKING DOWN, WITH THE WEATHER-SEALED COMPARTMENT OPEN. ALL EXPOSED WIRE IS AS A RESULT OF THE ISSUE, NOBODY HAS ACTIVELY CUT OR STRIPPED THE WIRES. PROBLEM FIRST NOTICED IN SEPT OF 2016, ATTEMPTS WERE MADE TO REPAIR BUT NOW IT HAS HAPPENED AGAIN, WORSE.

MY VEHICLE UNEXPECTEDLY STARTED ON FIRE AS MY DAUGHTER WAS DRIVING TO SCHOOL. IT WAS DETERMINED THAT IT WAS AN ELECTRICAL FIRE, AND RESULTED IN THE CAR BEING TOTALED. THE 2004 MODELS NEED TO BE INCLUDED IN THE RECALL (NOT THAT IT WILL HELP WITH THE LOSS OF MY CAR).

THE POWER DOOR LOCK ON PASSENGER SIDE CANNOT BE UNLOCKED EITHER VIA REMOTE OR INSIDE BUTTON. WORSE, OFTEN WHEN THIS HAPPENS, THE DOOR CANNOT BE OPENED EVEN BY PULLING ON THE HANDLE FROM THE INSIDE! A PASSENGER CANNOT GET OUT OF THE CAR VIA THE DOOR. FURTHERMORE, REPEATEDLY ATTEMPTS TO HAVE THIS FIXED ALL FAIL WITHIN A SHORT TIME.

I WAS NOT ABLE TO UNLOCK MY CAR WITH MY CAR KEY. I WAS ABLE TO HEAR THE CLICK SOUND ON PRESSING THE UNLOCK BUTTON ON THE KEY BUT NOTHING WAS HAPPENING. AFTER NUMEROUS ATTEMPTS FOR ABOUT 10 MINUTES CAR GOT UNLOCKED. NOW I'M HAVING THIS PROBLEM ON/OFF BASIS. I TOOK THE CAR TO THE LOCAL BMW DEALER. AFTER DIAGNOSE THEY SAID I HAVE A FAILED GENERAL MODULE WHICH WILL COST ME AROUND $1000. THIS IS WAY TOO MUCH FOR CAR FOR IT'S TOTAL VALUE OF AROUND $7000. THIS IS SCARY SINCE I'M NOT ABLE TO TRUST THE LOCKING SYSTEM ON MY CAR. SOMETIME I'M NOT ABLE TO LOCK AT ALL AND AT SOMETIME I'M NOT ABLE TO UNLOCK ANYTHING. *TR

THE HEATING ELEMENT ON MY 2004 BMW X3 CAUGHT ON FIRE WHILE I WAS DRIVING. I DON'T USE IT OFTEN, BUT HAD NOTICED A HOT SMELL WHEN I DID USE IT AND THAT IT WOULD BE TOO WARM IN THE LUMBAR AND HIP REGION. THE FIRE ACTUALLY BURNED ABOUT A DIME SIZE HOLE IN THE DRIVER SIDE LEFT SEAT PANEL (UNDER THE THIGH). AFTER READING OF MANY OTHERS HAVING THE SAME OR WORSE EXPERIENCES, I AM GLAD I IMMEDIATELY SHUT IF OFF, ALTHOUGH IT STILL BURNED ALL THE WAY THROUGH THE LEATHER. PLEASE ADVISE ME OF NEXT STEPS I SHOULD TAKE. I HAVE SHUT OFF THE HEATER AND WILL NO LONGER USE IT. WITH SO MANY COMPLAINTS, I WOULD THINK THIS WOULD RESULT IN A RECALL. THANKS FOR YOUR ADVICE. *TR

WIRE LOOSING COATING ON INSIDE OF ADAPTIVE HEADLIGHTS, CAUSING SHORTS OR BROKEN WIRES WHERE THE HEADLIGHTS AND OR TURN SIGNALS WILL FAIL TO WORK. WIRE IS VERY BRITTLE AS THIS IS ALSO ROUGHLY 20 GAUGE WIRE. THIS CAN BE AN EXTREME HAZARD ESPECIALLY AT NIGHT. THIS SEEMS TO BE AFFECTING BMW'S 3/5/6/ SERIES FROM AT LEAST 2004 TO 2008 FROM MY INDEPENDENT RESEARCH. MANY PICTURES AND COMPLAINTS ON VARIOUS BMW FORUMS TO DOCUMENT THIS PROBLEM. MY PROBLEM OCCURRED WHEN I LOST ONE HEADLIGHT ON MY WAY HOME IN THE DARK AND AN INDICATOR CAME ON TO IDENTIFY A FAULT IN THE HEADLIGHT. ORIGINALLY I THOUGH IT WAS A BULB, CHANGED BULB AND IT STILL DID NOT WORK. FURTHER INVESTIGATION LED TO A BROKEN WIRE INSIDE OF THE HEADLIGHT ASSEMBLY. I FIXED THE BROKEN WIRE AND THEN NOTICED TWO MORE WIRES WHERE THE COATING ON THE WIRE SEEM TO HAVE FLAKED OFF CAUSING BARE WIRE. I ALSO FIXED THOSE WIRES AND ALL WAS WELL. A DAY OR TWO LATER, THE INDICATOR CAME ON AGAIN POINTING TO THE SAME HEADLIGHT. THIS TIME THE TURN SIGNAL WAS OUT. I OPENED THE ACCESS PANEL TO CHECK THE WIRING AND NOW A FORTH WIRE HAS BEEN SEVERED, HOWEVER I CAN NOT FIX IT AS IT IS DOWN PRETTY FAR INSIDE THE HEADLIGHT AND TO REPAIR WOULD REQUIRE REMOVING THE HEADLIGHT AND TAKING IT APART. APPARENTLY BMW USED BIODEGRADABLE WIRE FOR THE HEADLIGHTS?? SOURCE OF THE HEADLIGHT IS BELIEVED TO BE HELLA. SUPPOSEDLY BMW KNOWS ABOUT THE ISSUE BUT UNWILLING TO FIX UNLESS YOU PURCHASE A $800-1500 NEW HEADLIGHT. THIS IS CRAZY FOR A CAR THAT IS 10 YEARS OLD AND WELL MAINTAINED. THIS IS A SAFETY HAZARD AS YOU WILL CAN LOOSE A HEADLIGHT IN THE DARK AND MAYBE BOTH HEADLIGHTS GOING OUT, PLUS THE FACT OF BARE WIRES THAT CAN SHORT AND CAUSE A FIRE. *TR

AS REPORTED BY OTHER OWNERS, THE BI-XENON HEADLIGHTS NO LONGER LIGHT UP THE ROAD. IT IS A SAFETY HAZARD AND IS A KNOWN ISSUE WITH HEADLIGHTS MANUFACTURED BY ZKW ON 2003-2005 BMW 330 MODELS. THE REFLECTOR BOWLS ON THESE UNITS BURN OUT OVER TIME AND REDUCE THE HEADLIGHTS ABILITY TO REFLECT LIGHT. DRIVING AT NIGHT IS LITERALLY NO BETTER WITH THE HEADLIGHTS ON OR OFF. I HAVE TO RELY ON MY FOG LIGHTS JUST TO SEE ANYTHING. PLEASE LOOK INTO THIS SAFETY ISSUE AS IT IS WIDE-SPREAD. REPLACEMENT OF HEADLIGHTS IS EXPENSIVE AT $1300 EA, THIS HAS TO BE RESOLVED BY BMW IMMEDIATELY. *TR

MY BI-XENON HEADLIGHTS HAVE BEEN SLOWLY FADING RESULTING IN EXTREMELY POOR VISIBILITY DURING NORMAL NIGHTIME DRIVING. THIS DEGRADATION HAS BEEN OCCURRING WITHOUT MY KNOWLEDGE UNTIL IT BECAME OBVIOUS AFTER DRIVING ANOTHER VEHICLE. AS IT TURNS OUT, MY MECHANIC HAS ADVISED THERE IS A COMMON ISSUE WITH CERTAIN BMW ASSEMBLIES THAT THE PROJECTOR LENSES LITERALLY BURN DUE TO HEAT RESULTING IN THE NEED TO REPLACE THE ENTIRE ASSEMBLY. THIS LOSS OF HEADLIGHT INTENSITY RESULTING IN POOR VISIBILITY IS A SIGNIFICANT SAFETY SITUATION AND REQUEST SOMEONE LOOK INTO WHY NO RECALL HAS OCCURRED AS THIS IS OBVIOUSLY A SAFETY CONCERN. I HAVE ENTERED TODAY'S DATE AS INCIDENT DATE AS I AM NOT SURE WHEN DEGRADATION OF THE PROJECTORS BEGAN. *TR

DOOR LOCKS INTERMITTENTLY WILL NOT UNLOCK WITH SWITCH OR REMOTES. CENTRAL LOCKING DOES NOT WORK EVEN WHEN USING THE KEY FOB. MY KIDS AND I HAVE BEEN TRAPPED IN THE CAR ON SEVERAL OCCASIONS FOR UP TO 10 MINUTES. THIS IS A SERIOUS RISK TO MY LIFE AND THE LIFE OF OTHERS ON THE ROAD. BMW REFUSES TO FIX THIS PROBLEM. I HAVE VIDEO OF ME TRAPPED IN THE CAR. I ADDRESSED HIS PROBLEM WITH BMW BEFORE MY WARRANTY WAS UP BUT THEY STATE SINCE THE TECHNICIANS COULD NOT IDENTITY ANY PROBLEM IT'S NOT COVERED. I RESEARCHED THIS ISSUE AND THIS IS AN ONGOING PROBLEM WITH OTHER CUSTOMERS. *TR

MODULE THAT CONTROLS CENTRAL LOCKING, WIPERS, AND SEVERAL OTHER PARTS (THE GM5) STARTED TO DEVELOP A FAULT. WE HAD PROBLEMS UNLOCKING DOORS, LOCKING DOORS, USING WINDOWS, AND WORST OF ALL - THE WIPERS WERE HIT OR MISS. BMW WANTED $750 FOR THE PART REPLACEMENT. *TR

2004 BMW 330XI SEDAN (E46) REAR TAIL LIGHT INDICATOR LIGHT CONSISTENTLY COMES ON, EVEN THOUGH THERE IS NO TAIL LAMP FAILURE. ONLINE COMMUNITY FORUMS REPORT THAT THIS IS LIKELY DUE TO GROUND WIRE SHORT IN THE TAIL LAMP ASSEMBLY. COST OF REPAIR AT DEALERSHIP ESTIMATED AT $700. CURRENTLY BEING INVESTIGATED BY NHTSA AS EA09-019, BUT I'M WARY OF BEING OVERCHARGED BY DEALERSHIP FOR WHAT SHOULD BE A RECALL. *TR

I WANT TO REPORT A PROBLEM WITH THE IGNITION COILS IN THE BMW 330XI MODEL MADE IN THE YEAR 2004 THAT RESULTS IN REDUCED IGNITION FIRING POWER. THE ENGINE RUNS ROUGH AND THE "SERVICE ENGINE SOON" LIGHT ILLUMINATES. BMW HAD A RECALL ON IGNITION COILS FAILURE IN 2005 AND 2006 ON SOME MODELS BUT THIS PROBLEM NOW SURFACE ON OTHER MODELS AS WELL. PLEASE INVESTIGATE. *TR
