I inherited my dad's 2003 Mercedes Benz E320 when he passed away last year. He kept the car in pristine condition. About a month ago while driving it, I noticed a strong smell of gasoline in the cabin of the vehicle. The odor is strong just after filling the tank, and then it disappears at appox. 3 quarters of a tank. This issue has been physically challenging for me, making me dizzy and giving me migraines. I'm also very concerned about the safety issues relating to gasoline fumes inside the car... My understanding is that this is a common issue for the said Mercedes Benz model and year. It is a dangerous parts defect that is unacceptable.

Defect investigations
Fuel Leakage From The Fuel Tank
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

What 2003 Mercedes Benz E320 owners say
Most recent owner complaints, unedited.
The contact owns a 2003 Mercedes-Benz E-320. The contact stated while driving 30 MPH, the braking system became inoperable. The contact stated that the ABS warning light was illuminated after the failure. The contact stated that the failure was related to TSB: 2005110001. The contact called the local dealer and was informed that the VIN was not under recall. The vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, who stated that the failure was due to the sensotronic brake control (SBC) braking system. The manufacturer was contacted and the contact was informed that the VIN was not under recall for the failure. The failure mileage was unknown.
MB USA is not honoring Recall 2005110001 for 25 years per the federal safety agency Bulletin. The Mercedes Benz Representative said that the recall is closed for a 2003 car, but which should not be closed until 2028 for my car. The Mercedes Benz Representative agreed that she does see the car matches the 2003-2006 E class with chassis of A336226 falling between A0- and A7- for the recall. The Mercedes Benz Representative gave no explanation as to why the 25 year recall has closed prior to 2031. The faulty SBC has caused numerous problems. If the recall is not honored, I plan to file a lawsuit against Mercedes. A formal complaint is being filed with the federal safety agency for MB USA's lack of adhering to the recall for the full 25 years.
