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

AT AROUND 20K MILES, THE SMG (SEQUENTIAL MANUAL GEARBOX W/ PADDLE SHIFTERS) ON MY '04 325CI BEGAN EXPERIENCING MANY OF THE SAME PROBLEMS THAT I'VE READ ABOUT REGARDING THE AUTOMATIC TRANSMISSION. AFTER A COLD NIGHT, THE SMG WOULD NOT SHIFT INTO REVERSE OR DRIVE. IT WOULD KEEP "CLUNKING" OVER AND OVER, CONTINUALLY LOUDER, UNTIL I SHIFTED BACK INTO NEUTRAL. I HAD THE CAR TOWED TO BMW, WHERE THEY HAD TO REPLACE THE TRANNY. AT 83K MILES, I'M STARTING TO NOTICE SOME OF THE SAME PROBLEMS AGAIN. ADDITIONALLY, WITH BOTH TRANNYS, THE CAR DELAYS ITS ACCELERATION FOR ABOUT A SECOND OR TWO WHEN STARTING FROM A STOP. THIS HAS ALWAYS BEEN A PROBLEM. ON TOP OF THAT, MY ALTERNATOR JUST WENT OUT AFTER A COLD NIGHT. IN MY OPINION, BMW'S (AT LEAST MINE) DO NOT LIKE THE COLD! *TR

TL* THE CONTACT OWNS A 2004 BMW 325XI. THE WIRE THAT PLUGS INTO THE DRIVER SIDE REAR TAIL LIGHT HARNESS BURNED WHICH MAKES IT IMPOSSIBLE FOR THE DRIVER TO ALERT OTHERS OF HIS INTENTIONS REGARDING DIRECTION OF TRAVEL AND SPEED. TECHNICAL SERVICE BULLETIN # 10020856(EXTERIOR LIGHTING:TAIL LIGHTS) SUMMARIZES THE FAILURE. THE FAILURE HAS NOT BEEN REMEDIED. THE CURRENT AND FAILURE MILEAGES WERE 59,770. UPDATED 12/09/09 *BF THE CONSUMER STATED THE SAME FAILURE HAPPENED ON THE PASSENGER SIDE. THERE WAS INSUFFICIENT GROUNDING WHICH CAUSED THE BURNOUT OF THE TAIL LIGHT WIRING.

THIS IS A FORMAL PETITION FOR A SAFETY DEFECT INVESTIGATION. MY 2004 BMW 325XI HAS A LEFT TAIL LIGHT THAT DOES NOT WORK BECAUSE OF A POOR CONNECTION AT THE REAR LAMP CONNECTOR (THE GROUND WIRE RECEPTACLE AND HOUSING HAVE BURNT OUT BECAUSE THE GROUND IS NOT STRONG ENOUGH FOR THE CURRENT). MY RIGHT TAIL LIGHT STILL FUNCTIONS BUT I AM CONCERNED ABOUT THIS SIDE BURNING OUT AS WELL AND POSING A POSSIBLE FIRE HAZARD. BMW HAS ISSUED A SERVICE BULLETIN (SI B 63 03 06) WHICH ADDRESSES THIS ISSUE AND SAYS THAT THE CAUSE IS "MINOR CORROSION AT THE 8-PIN REAR LAMP CONNECTOR CREATES HIGH RESISTANCE CAUSING DAMAGE TO THE CONNECTOR HOUSING." BMW HAS NOT ISSUED A RECALL AND I AM WORRIED ABOUT GETTING INTO AN ACCIDENT WITHOUT A PROPERLY FUNCTIONING TAIL LIGHT. *TR

AT FIRST I THOUGHT IT WAS DEFECTIVE LIGHT BULBS (ONE FROM TWO DIFFERENT SETS FAILED WHEN ONE SET WAS INSTALLED FOR MY TURN SIGNAL AND THE OTHER FROM MY BRAKE LIGHTS), BUT AS I BEGAN TO DO MORE RESEARCH ONLINE, I FOUND THAT OTHER PEOPLE WERE HAVING AN ISSUE SIMILAR TO MINE. THEY REPORTED THAT THERE SEEMED TO BE AN ELECTRICAL PROBLEM THAT WOULD CAUSE CORROSION AND A LOOSE CONNECTION. SO I DECIDED TO CHECK MY CAR OUT AS WELL AND DISCOVERED THAT THE PROBLEM HAD AFFLICTED MY VEHICLE AS WELL. I THEN FOLLOWED THE LINK TO THE TECHNICAL SERVICE BULLETIN RELEASED BY BMW, AND THE PROBLEM THAT I AM HAVING IS JUST AS THEY HAVE DESCRIBED. ONE OF THE 8-PIN REAR LAMP CONNECTORS HAS MELTED CAUSING A LOOSE CONNECTION AND MY CAR CONTINUING TO TELL ME THAT I HAVE A DEAD BULB, WHEN IN FACT IT IS THE CONNECTION. *TR

TL*THE CONTACT OWNS A 2004 BMW 325I. THE CONTACT STATED THAT THE FAULTY LAMP WARNING INDICATOR WOULD INTERMITTENTLY ILLUMINATE ON THE INSTRUMENT PANEL. THE ELECTRICAL HARNESS THAT PLUGS INTO THE REAR OF THE LAMP HARNESS FOR THE EXTERIOR LIGHTING HAD A FAULTY GROUND IN THE CONNECTOR. THE DEALER STATED THAT THE WIRES COULD NOT TAKE THE HEAT DISTRIBUTION, WHICH CAUSED THE WIRES TO FRY INSIDE THE CONNECTOR. THE FAILURE ALSO CAUSED THE TURN SIGNALS AND REAR LAMPS TO NOT OPERATE CORRECTLY. THERE WERE NO RECALLS FOR THE FAILURES; HOWEVER, THE CONTACT WAS ABLE TO LOCATE TECHNICAL SERVICE BULLETINS PERTAINING TO THE ISSUES (NHTSA ITEM NUMBERS 10025585 AND 10020856). THE CURRENT AND FAILURE MILEAGES WERE 85,000.

SPEEDOMETER READING OFF BY ~5 MILES PER HOUR - GIVE OR TAKE. TWICE REQUESTED DEALERSHIP TO CORRECT THE ISSUE AND WAS TOLD THAT BMW ALLOWS FOR A +/ - 10 MPH DISCREPANCY. THIS SPEED VARIANCE OR INEXACT SPEED INFORMATION COULD MISLEAD DRIVERS AS TO THE APPROPRIATE SPEED IN ICY OR RAINY WEATHER CONDITIONS AS WELL AS OTHER INSTANCES WHERE SPEED NEEDS TO BE UNDERSTOOD. DEFECT NEEDS TO BE CORRECTED AS MIGHT VIOLATE VARIOUS STATE INSPECTION REQUIREMENTS AS WELL. *TR
