1995 MERCEDES BENZ, E-300D EVENTS LEADING UP TO THE FAILURE: NONE, NORMAL USE OF THE VEHICLE THE FAILURE, HOW OFTEN IT OCCURS, ITS CONSEQUENCES: WIRING AND GLOW PLUG HARNESS FAILURE, CAUSED BY BAD INSULATION ON THE WIRES THE INSULATION ON BOTH HARNESSES WAS PEELING/COMING OFF EXPOSING BARE COPPER WIRE, CAUSING SHORTS AND HARD COLD STARTS. I CALLED MERCEDES BENZ DIRECT AND THEY "HAVE NO KNOWLEDGE"OF THIS PROBLEM ON THESE CARS. I THEN FIND OUT THIS IS A COMMON OCCURRENCE ON 1990-1995 300 SERIES VEHICLES AND HAS CAUSE FIRES IN THE PAST. WHAT WAS DONE TO CORRECT THE FAILURE: I HAD A LOCAL INDEPENDENT REPAIR FACILITY REPLACE BOTH HARNESSES AT MY EXPENSE. THE OLD HARNESSES WERE THROWN OUT. MERCEDES BENZ STILL SAYS THERE IS NOTHING WRONG WITH THE HARNESSES. *TR

VEHICLE NOT OPERATING PROPERLY, BLOWING FUSES, WARNING LIGHTS COMING ON, ENGINE COOLING FAN NOT OPERATING PROPERLY, AND ENGINE OVERHEATING. INSPECTION REVEALED THAT THE INSULATION IS SEVERELY DETERIORATED ON THE ENGINE WIRE HARNESS (MERCEDES BENZ PART NUMBER 124-440-32-32). THE INSULATION ON ALMOST ALL OF THE WIRES IN THE ENGINE COMPARTMENT HAS BECOME BRITTLE AND CRACKED OPEN AND LARGE PORTIONS OF THE INSULATION HAVE FALLEN OFF LEAVING BARE WIRES EXPOSED WHICH ARE CAUSING SHORT CIRCUITS AND GROUND CIRCUITS. THERE IS A HIGH PROBABILITY THAT OPERATING A VEHICLE IN THIS CONDITION COULD CAUSE THE VEHICLE TO STALL, LOSE POWER, CATCH ON FIRE, OR CAUSE OR RESULT IN AN ACCIDENT. THE OWNER OF THE VEHICLE HAS INQUIRED WITH THE MERCEDES DEALER WHERE THE CAR WAS PURCHASED. THE SERVICE TECHNICIAN STATES THAT THEY HAVE HAD TO REPLACE A VERY HIGH NUMBER OF THESE ENGINE WIRE HARNESSES. THE OWNER SHALL ORDER THE CORRECT PART AND A QUALIFIED TECHNICIAN SHALL REMOVE AND REPLACE IT. THE OWNER SHALL SAVE T

1995 MERCEDES-BENZ E300D WIRING HARNESS: TEMPERATURE READING NOT ACCURATE, THOUGH ON THE HIGH SIDE SO I FEEL LIKE THE CAR IS OVERHEATING BUT REALLY NOT ENGINE IDLE SENSOR INACCURATE LEADING TO READING OF LOW RPM AT IDLE AND TACHOMETER NOT ALWAYS WORKING OTHER CONSEQUENCES: AUXILIARY FANS MOTORS BLOWN DUE TO FANS RUNNING AT HIGH SPEED ALWAYS INSTEAD OF VARIABLE AND INTERMITTENT.

THE ENGINE WIRING HARNESS AND EA/CC/ISC WIRING INSULATION HAS BADLY DETERIORATED ON MY 1995 E300 DUE TO HEAT FATIGUE FROM POOR MANUFACTURING. THE DECAY HAS REACHED THE POINT OF LEAVING BARE EXPOSED WIRE WITHIN THE HARNESS. THESE WIRES MAKE CONTACT CAUSING THE ENGINE TO STALL, SURGE, A/C COMPRESSOR NOT TO WORK, AND SET MISC. ENGINE CODES. THIS IS A KNOWN PROBLEM TO OWNERS OF THESE VEHICLES AS EVIDENCED BY CONVERSATION THREADS ON SEVERAL WELL REGARDED FORUMS. THE GENERAL UNDERSTANDING IS THAT MERCEDES WAS ATTEMPTING TO CREATE ECO-FRIENDLY WIRE INSULATION THAT WOULD DEGRADE IN THE LANDFILL. IT WAS A GREAT IDEA, BUT HAS FAILED MISERABLY. IN MY OPINION SOMEONE IS GOING TO BE SERIOUSLY INJURED IF THIS PROBLEM IS NOT RESOLVED WITH A RECALL. NOW. THERE ARE SEVERAL REPORTS OF ENGINE FIRES FROM THIS WIRING FAILURE. THIS IS NOT BY ANY STRETCH OF THE IMAGINATION A PART THAT IS PRONE TO FAILURE. MY FEELING IS THAT BY WAITING IT OUT MERCEDES IS HOPING THESE CARS WILL JUST GO AWAY. QUITE FRANKLY IT

1995 MERCEDES E 300 DIESEL, THE ENGINE WIRING HARNESS IS FALLING APART. THE INSULATION IS CRUMBLING AND ALL THE WIRES ARE SHORTING CAUSING MALFUNCTIONS OF ALL ENGINE SYSTEMS, AND COULD CAUSE A FIRE. IMPOSSIBLE TO FIX THE CURRENT HARNESS BECAUSE EVERY WIRE IS INVOLVED, HAVE TO REPLACE. I HAVE NEVER SEEN THIS BEFORE, I HAVE HAD MANY CLASSIC CARS THAT ARE MUCH OLDER THAN THIS THAT HAVE PERFECT WIRING TO THIS DAY. I WAS TOLD BY A NON-MERCEDES SHOP THAT THIS WAS AN ATTEMPT BY MERCEDES TO MAKE THE INSULATION EASILY TO RECYCLE AND THAT ALL CARS OF THIS PERIOD HAVE THIS PROBLEM SOONER OR LATER. *JB
