THE INSULATION COVERING THE ELECTRICAL WIRING THAT POWERS THE LOW BEAM HEADLIGHTS ON BOTH PASSENGER AND DRIVER SIDES HAS FAILED AND CRUMBLED AWAY EXPOSING THE BARE COPPER WIRE. THIS CIRCUIT POWERS TWO HALOGEN 55 WATT BULBS (110 WATTS TOTAL OR ~10 AMPS) AT 12 VOLTS. THE INSULATION FAILURE WILL PRESENT AN IMMEDIATE VEHICLE FIRE HAZARD IF THE ELECTRICAL PROTECTION FUSE FAILS TO ACTUATE AS A RESULT OF THE SHORT CIRCUIT CREATED BY POTENTIAL BARE WIRE CONTACT. IF THE ELECTRICAL PROTECTION FUSE DOES ACTUATE PROPERLY THE CAR WILL LOSE FORWARD ILLUMINATION WHICH IS ESSENTIAL FOR SAFE VEHICLE OPERATION AT NIGHT. IN EITHER INSTANCE A PROPERTY AND PERSONAL HAZARD CAN RESULT FROM THIS DEFECT. THIS DEFECT CAN BE TRACED DIRECTLY TO THE WIRE MERCEDES BENZ SELECTED FOR THE MANUFACTURE OF THIS CIRCUITRY. EITHER THE GAUGE OF THE WIRE SELECTED IS INSUFFICIENT TO DISSIPATE THE HEAT GENERATED BY THE CURRENT FLOW THE CIRCUIT DEMANDS OR THE INSULATION OF THE WIRE SELECTED IS INHERENTLY DEFECTIVE AS EVIDENCED BY ITS CRUMBLING DETERIORATION FOR A COMPONENT THAT SHOULD BE EXPECTED TO LAST THE LIFE OF THE VEHICLE. IN EITHER CASE THIS WIRING FAILURE CONSTITUTES A MANUFACTURING DEFECT WHICH SHOULD BE SUBJECT TO RECALL AND CORRECTION BY THE MANUFACTURER AT HIS EXPENSE. THE DEFECT WAS DISCOVERED WHILE ATTEMPTING TO REPLACE A FAILED LOW BEAM HEADLIGHT BULB, A MAINTENANCE ACTIVITY THAT CAN REASONABLY BE EXPECTED TO BE PERFORMED A NUMBER OF TIMES DURING THE VEHICLE'S LIFESPAN. THE DEFECTIVE INSULATION WAS IMMEDIATELY EVIDENT BY VISUAL AND TACTILE OBSERVATION. IT WAS IMMEDIATELY CLEAR AN IMMEDIATE HAZARD WAS PRESENT AND THAT THE LIGHTING COULD NOT BE USED RENDERING THE VEHICLE UNSAFE TO OPERATE UNDER CONDITION WHEN THE LIGHTING CIRCUIT MIGHT BE OPERATED.

DURING RENEWAL OF HEADLAMP BULBS I FOUND THAT INSULATION HAD BROKEN OFF LEAVING SUBSTANTIAL PORTION OF BARE CONDUCTORS.

DURING RENEWAL OF HEADLAMP BULBS I FOUND THAT INSULATION HAD BROKEN OFF LEAVING SUBSTANTIAL PORTION OF BARE CONDUCTORS. WIRES ARE IN CLOSE PROXIMITY TO EACH OTHER AND IF THEY TOUCH THERE IS THE POSSIBILITY OF LOSS OF LIGHTING OR ELECTRICAL FIRE. SHOULD THIS OCCUR, WHILE DRIVING ON A DARK ROAD, IT LIKECOULD RESULT IN CATASTROPHIC CRASH. THIS IS COMMONLY DISCUSSED BY OWNERS IN THE MERCEDES-BENZ FORUMS. I AM SURPRISED THAT MERCEDES HAS NOT BEEN FORCED TO RECALL W211S FROM 2003 TO 2009 MODEL YEARS. *TR

I CHANGED THE LOW BEAM HALOGEN BULBS IN MY HEADLIGHTS WHEN I DISCOVERED THAT THE WIRE LEADS TO THE BULB HAD LOST NEARLY ALL OF THEIR INSULATION, EXPOSING BARE WIRE. THE INSULATION FLAKES WERE SITTING IN THE BOTTOM OF THE CAPSULE THAT CONTAINS THE LIGHT ASSEMBLY, WHICH IS NORMALLY CLOSED, ACCESSED BY A REMOVABLE "DOOR". BOTH HEADLIGHTS HAD THIS SAME ISSUE. THIS IS AN OBVIOUS SPARKING/FIRE DANGER, SO I APPLIED ELECTRICAL TAPE OVER THE WIRES. HAD I NOT CHANGED THE BULBS [THEY LOSE BRIGHTNESS OVER THE YEARS], I WOULD HAVE BEEN UNAWARE OF THIS DANGER. I AM CONCERNED THAT THIS SAME WIRE INSULATION HAS BEEN USED THROUGHOUT THE VEHICLE. I AM AMAZED THAT MERCEDES HAS NOT ISSUED A RECALL ON THIS. I PURCHASED THIS CAR NEW IN 2007. *TR

IN MY OPINION, THE NHTSA DROPPED THE BALL WHEN THEY APPROVED THE HID AUTOMOBILE HEADLIGHT SYSTEM ON SOME NEWER MODEL CARS. THE GLARE THESE HEADLIGHTS PRODUCE IS VERY DISTURBING AND IN MY OPINION,THIS STANDARD SHOULD BE REVISITED AGAIN BY THE NHTSA, AND REVISED WITH NEW ANTI-GLARE PARAMETERS. *JB

PE10017 · Driver Air Bag Circuit High Resistance

Opened May 14, 2010 · Closed Nov 24, 2010

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Electrical System; Electrical System:wiring; Electrical System:wiring:interior/under Dash

Mercedes-Benz USA (MBUSA) has reported a high number of warranty claims for air bag warning lamp illumination due to a diagnostic fault code 9103 or 9123 indicating a high resistance in the driver's frontal air bag firing circuit.MBUSA's testing and evaluation have shown that this condition is the result of a faulty connector (specifically, improper wire crimp) but that it will not prevent proper deployment of the driver's frontal air bag.The faulty connector can cause the air bag circuit resistance levels to exceed the threshold that illuminates the air bag warning lamp, but they do not exceed a higher limit at which proper deployment of the air bag may no longer occur.The agency believes that further expenditure of agency resources does not appear to be warranted at this time.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.During the investigation, ODI learned that MBUSA will initiate a warranty extension program to address the faulty connectors in subject model year 2005 and 2006 E-Class and other MBUSA model/model year vehicles.This action will extend the warranty coverage for this issue to 10 years or 100,000 miles, whichever occurs first.MBUSA will notify all affected vehicle owners of this action.A bulletin describing this program is available in the investigative file.
