LEAKY FUEL SENDING UNIT. I BROUGHT MY 2008 E63 AMG INTO MERCEDES OF BOSTON FOR TO REPAIR A LEAKING FUEL SENDING UNIT AROUND THE SPRING OF 2015. I REALIZE THIS WAS AN ISSUE FOR MANY E CLASS AND WAS BEING INVESTIGATED BY NHTSA. I SPECIFICALLY ASKED MY SERVICE ADVISOR IF MERCEDES WAS AT LEAST COVERING PART OF THE REPAIR. HE SAID THERE WAS NO WARRANTY COVERAGE ON IT. I PAID $900 FOR THE REPAIR. I JUST FOUND OUT ON THE NHTSA THAT MERCEDES GAVE AN EXTENDED WARRANTY COVERAGE FOR FUEL RELATED PARTS FOR 15 YEARS AS OF SEPTEMBER 2014. MERCEDES IS DELIBERATELY HIDING THESE DETAILS FROM CONSUMERS. NO NOTIFICATIONS WAS EVER SENT. NO REFUNDS OFFERED.

ON JULY 30TH, 2014 I FUELED MY 2008 MERCEDES E63 AMG IN THE SAME MANNER AS I HAVE FOR THE PAST 3 YEARS OF OWNERSHIP. WHEN I PARKED MY VEHICLE IN THE GARAGE AND CLOSED THE DOOR I NOTICED A FAINT ODOR OF GASOLINE. I THOUGHT IT WAS JUST THE EXHAUST FUME BUILT UP IN THE ENCLOSED ENVIRONMENT. THE NEXT DAY WHEN I CHECKED, THERE WAS AN OVERWHELMING ODOR OF GASOLINE. FUMES WERE SO STRONG I COULD CLEARLY SMELL IT FROM MY FLOOR APARTMENT. LUCKILY MY NEIGHBOR WERE AWAY ON VACATION. THE SMELL OUTSIDE THE ENTRY WAY INTO THE GROWERS WAS SO STRONG IT STUNG MY EYES. KNOWING THE VOLATILITY GAS VAPORS I IMMEDIATELY OPENED THE GROWERS DOOR. WHEN I LOOKED UNDER THE REAR WHEEL ARCH OF THE DRIVER SIDE I SAW A PUDDLE ODD GASOLINE AND INTERMITTENT DROPS OF GASOLINE COMING DOWN FROM THE FUEL TANK AREA. THE GASOLINE DID NOT STOP LEAKING UNTIL I DRIVE IT TO ABOUT 3/4 FULL. IT TOOK 2 WEEKS FOR THE SMELL OF GASOLINE TO DISSIPATE FROM THE INTERIOR. I AM AWARE OF THE CLASS ACTION LAWSUIT AGAINST MERCEDES FOR THIS VERY SAME PROBLEM. *TR

I PURCHASED A 2008 E63 MERCEDES BENZ IN DECEMBER 2013. SINCE THE DATE OF PURCHASE I HAVE NOTICED A STRONG ODOR AND SMELL OF GASOLINE UPON FUELING THE AUTOMOBILE(BOTH INSIDE AND OUTSIDE OF THE VEHICLE). THIS ODOR PROGRESSIVELY GOT STRONGER UNTIL I WAS UNABLE TO CLOSE MY GARAGE DUE TO THE FUMES AND THE FEAR FOR MY SAFETY. I TOOK THE CAR TO A MERCEDES BENZ DEALER (LUCKILY) TO HAVE IT CHECKED OUT PRIOR TO A ROAD TRIP ON 7/2/2014 AND IT WAS DETERMINED THERE WAS A LEAK IN THE FUEL TANK AND SENDING UNIT (S). THE TECHNICIANS AT THE MERCEDES BENZ DEALERSHIP INDICATED TO ME THAT THE VEHICLE WAS UNSAFE TO DRIVE AND OPERATE. I HAVE DISCOVERED THAT THIS PARTICULAR ISSUE IS COMMON TO MY PARTICULAR VEHICLE MAKE, MODEL AND YEAR (A RECALL OR CLASS ACTION LAWSUIT HAS BEEN DONE AGAINST MB FOR THIS PROBLEM). I HAD THE REPAIRS DONE AT MERCEDES BENZ BUT WAS CHARGED FOR THE REPAIRS. I SEEK TO RECOVER THE REPAIR COSTS ASSOCIATED WITH THIS INCIDENCE. PLEASE CONTACT ME IMMEDIATELY AS I NEED GUIDANCE AND INFORMATION REGARDING THIS SITUATION. *TR

REFERENCE NHTSA ACTION NUMBER: PE12001. I PURCHASED THIS VEHICLE USED IN DECEMBER 2012. ONE DAY AFTER FILLING UP WITH FUEL I PARKED THE CAR IN MY GARAGE. THE NEXT DAY I CAME OUT TO MY GARAGE AND THERE WAS A STRONG SMELL OF GASOLINE. WHEN I GOT INSIDE OF MY CAR THE SMELL GOT MUCH STRONGER AND IT WAS UNBEARABLE. I COULD NOT FIND ANY LEAKS INSIDE OR OUTSIDE OF THE VEHICLE. I HAD TO DRIVE TO WORK AND THIS WAS THE ONLY CAR AVAILABLE. THIS WAS IN THE DEAD OF WINTER AND I HAD TO DRIVE WITH THE WINDOWS DOWN BECAUSE THE GAS SMELL AND FUMES WERE UNBEARABLE. I HAD A TERRIBLE HEADACHE FOR THE REST OF THE DAY. I LEFT MY CAR WITH THE WINDOWS ROLLED DOWN TO HELP AIR IT OUT. WHEN I RETURNED HOME I DID SOME RESEARCH ONLINE AND FOUND OUT THIS IS A FAR TOO COMMON PROBLEM WITH THE W211 CHASSIS MERCEDES BENZ. PER THE INFORMATION ONLINE I WAS INSTRUCTED TO REMOVE MY REAR PASSENGER SEAT AND CHECK THE FUEL SENDING UNITS UNDERNEATH THE SEATS. SURE ENOUGH WHEN I REMOVED THE COVER OFF THE DRIVERS SIDE FUEL SENDING UNIT THERE WAS A POOL OF GASOLINE! I CLEANED UP ALL OF THE GASOLINE AND LET IT DRY OUT. FROM THIS POINT ON I HAVE NOT FILLED UP MY GAS TANK MORE THAN 3/4 JUST TO KEEP THIS FROM HAPPENING AGAIN. FUEL POOLING INSIDE OF THE CABIN IS DANGEROUS AND UNHEALTHY. MERCEDES BENZ DENIES THAT THIS IS A PROBLEM AND WILL NOT COVER THE COST OF REPLACING/FIXING THE DEFECTIVE FUEL SENDING UNITS. THERE ARE HUNDREDS IF NOT THOUSANDS OF OTHERS THAT HAVE THIS ISSUE. PLEASE DO SOMETHING TO GET THIS RESOLVED. I HAVE PICTURES OF THE FUEL POOLING INSIDE OF THE CABIN. *TR

1EA13003 · Fuel Leakage From The Fuel Tank
Opened Mar 15, 2013 · Closed Dec 19, 2014
Status: closed (inferred from source dates) · Fuel System, Gasoline; Fuel System, Gasoline:delivery; Fuel System, Gasoline:delivery:fuel Pump; Fuel System, Gasoline:delivery:hoses, Lines/piping, And Fittings; Fuel System, Gasoline:storage; Fuel System, Gasoline:storage:tank Assembly
The Office of Defects Investigation (ODI) opened this investigation on January 23, 2012 as PE12-001 based on 20 consumer reports in model year (MY) 2003-2006 E55 AMG vehicles.Based on new reports in other E-Class vehicles, ODI upgraded the investigation to Engineering Analysis (EA) 13-003 on March 15, 2013, and expanded the scope to all E-Class vehicles through MY 2008.The complainants alleged a strong odor of gasoline fuel both inside and outside of their vehicle, particularly after refilling the fuel tank.Many of the complainants noted that the odor subsided or went away after driving some distance thereby lowering the fuel level in the tank.Other owners reported they would only fill the tank to about three quarters full to avoid the odor altogether.Some complainants alleged fuel leaked from the fuel filter/sender, located on the top of the fuel tank on the driver's side, and collected on top of the tank.There were also allegations that the fuel leaks were associated with an Emissions Recall Campaign (No. 2008020001) conducted by Mercedes-Benz USA, LLC (Mercedes) in 2008 on MY 2003-2006 E-Class and CLS-Class AMG models.The issue in the recall involved small cracks in the pressurized outlet fitting of the fuel filter/sender.AMG vehicles are high performance models that operate at higher fuel pressure and use a different fuel filter/sender and fuel pump than non-AMG models.Information on Recall No. 2008020001 is available from the U.S. Environmental Protection Agency (EPA) website at www.EPA.gov.ODI's investigation found various leak sources that are unrelated to the outlet fitting cited in the EPA recall campaign.Through interviews with complainants, field inspections of complaint vehicles, and the collection and laboratory analysis of failed parts, three identifiable leak sources were found.The component parts and areas of the leaks involve the On-Board Diagnostic fuel tank pressure sensor (located on top of the fuel filter/sender), the outlet of the centrally mounted fuel tank fuel filling limiter valve, and the top of the fuel pump. These areas of leakage are located at the top of the fuel tank in unpressurized parts of the fuel system. When the tank is full, fuel can slowly weep/seep from micro-cracks in these components and may collect in cavities on top of the filter/sender, pump, or tank.Contrary to complainant's allegations that fuel entered the inside of their vehicle under the rear seat bench, neither ODI nor Mercedes found a plausible way for this to occur.The fuel tank is located outside of the passenger compartment, attached to the underside of the vehicle.The service access ports for the fuel filter/sender (driver's side) and fuel pump (passenger's side) are located under the rear seat bench, covered by a steel plate, sealed and bolted to the vehicle floor.When technicians service the fuel filter/sender, which has a regularly scheduled 60,000 mile service interval, and/or the fuel pump, the work is performed from inside the vehicle by working through the access ports.By letter dated September 4, 2014, Mercedes has notified the agency that it will extend the original warranty coverage to 15 years and unlimited mileage on Covered Fuel Tank Components in E-Class vehicles in MY 2003-2009 and CLS-Class vehicles in MY 2006-2011.The covered fuel tank components for the warranty extension include the fuel tank, fuel filter/sender, fuel pump, and all related gaskets/seals and retention rings.ODI is closing this investigation based on the manufacturer's extend warranty of the affected fuel system components and in consideration that the nature of the leaks does not appear to present an un

When the tank is full, fuel can slowly weep/seep from micro-cracks in these components and may collect in cavities on top of the filter/sender, pump, or tank.Contrary to complainant's allegations that fuel entered the inside of their vehicle under the rear seat bench, neither ODI nor Mercedes found a plausible way for this to occur.The fuel tank is located outside of the passenger compartment, attached to the underside of the vehicle.The service access ports for the fuel filter/sender (driver's side) and fuel pump (passenger's side) are located under the rear seat bench, covered by a steel plate, sealed and bolted to the vehicle floor.When technicians service the fuel filter/sender, which has a regularly scheduled 60,000 mile service interval, and/or the fuel pump, the work is performed from inside the vehicle by working through the access ports.By letter dated September 4, 2014, Mercedes has notified the agency that it will extend the original warranty coverage to 15 years and unlimited mileage on Covered Fuel Tank Components in E-Class vehicles in MY 2003-2009 and CLS-Class vehicles in MY 2006-2011.The covered fuel tank components for the warranty extension include the fuel tank, fuel filter/sender, fuel pump, and all related gaskets/seals and retention rings.ODI is closing this investigation based on the manufacturer's extend warranty of the affected fuel system components and in consideration that the nature of the leaks does not appear to present an un
