I FILLED THE TANK OF OUR E320 CDI WITH DIESEL FUEL AT A LOCAL STATION AND DROVE THE SHORT DISTANCE HOME AND PARKED IN MY GARAGE. NEXT MORNING I NOTICED A PUDDLE OF DIESEL FUEL NEAR RIGHT-REAR TIRE.

I FILLED THE TANK OF OUR E320 CDI WITH DIESEL FUEL AT A LOCAL STATION AND DROVE THE SHORT DISTANCE HOME AND PARKED IN MY GARAGE. NEXT MORNING I NOTICED A PUDDLE OF DIESEL FUEL NEAR RIGHT-REAR TIRE. I DRIVE THE CAR NORMALLY TO WORK (~5 MILES) THE NEXT FEW DAYS AND NOTICED A PUDDLE OF DIESEL NEAR RIGHT REAR TIRE EACH TIME. DID A LITTLE ON-LINE RESEARCH AND LEARNED THERE IS AN ISSUE WITH THE FUEL SENDER SEAL ON W211 MB'S, LIKE MINE. SCHEDULED AN APPOINTMENT WITH MB OF GRAND BLANC AND THEY CONFRMED THE DIAGNOSIS AND REPLACED THE SEAL UNDER MY EXTENDED WARRANTY. IF I WERE NOT UNDER WARRANTY, MB WOULD HAVE REFUSED TO PAY, FROM WHAT PEOPLE WITH SAME PROBLEM ARE REPORTING ON MB FORUMS. THIS IS RIDICULOUS THAT SUCH A PROBLEM WOULD HAPPEN ON A MB. MINE IS A DIESEL, SO A FIRE WAS UNLIKELY, BUT THIS HAPPENS WITH GAS VERSIONS AS WELL AND THAT IS DANGEROUS. MB SHOULD BE FORCED TO DO A RECALL. *TR

I NOTICED FUEL STAINS ON BOTTOM OF FUEL TANK AND SMELL OF DIESEL IN MY GARAGE ESPECIALLY AFTER FILL UP. I TOLD THE DEALER WHEN I HAD THE CAR IN FOR SERVICE.

I NOTICED FUEL STAINS ON BOTTOM OF FUEL TANK AND SMELL OF DIESEL IN MY GARAGE ESPECIALLY AFTER FILL UP. I TOLD THE DEALER WHEN I HAD THE CAR IN FOR SERVICE. THEY SAID I HAD A FUEL LEAK AND THE FUEL TANK WOULD HAVE TO BE REMOVED TO FIND THE SOURCE. THEY SAID THE PROBLEM COULD BE THE TANK, SENDING UNIT, OR SEALS....ALL VERY EXPENSIVE TO DIAGNOSE/ REPAIR. I MET WITH THE SERVICE MGR TO SEEK AN OUT OF WARRANTY COVERAGE AND GOT NOTHING. I CALLED MERCEDES CORPORATE CUSTOMER SERVICE. THEY DECLINED TO COVER ANY OUT OF WARRANTY REPAIR COSTS. I REMOVED THE REAR SEAT AND FOUND FUEL PUDDLING AROUND THE SENDING UNIT (IN THE TANK) ON THE DRIVER?S SIDE. IT IS UNCONSCIONABLE THAT THERE ARE FUEL LEAKS IN A HIGH LINE EXPENSIVE CAR LIKE THIS. MERCEDES CUSTOMERS SHOULD RIGHTFULLY EXPECT A LEAK FREE FUEL TANK FOR THE LIFE OF THE CAR. IT IS SHAMEFUL THAT MERCEDES DOESN'T OWN UP TO IT AND ISSUE A RECALL NOTICE AND FIX THIS BEFORE SOMEONE IS KILLED. *TR

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.
