Four problems related to other fuel system pump have been reported for the 2006 Mercedes Benz E55. The most recently reported issues are listed below.
Strong smell of gas around rear of driver side and also inside of car. I removed the back seat and fuel pump cover to find gas pooling inside the compartment. Gas was also streaming out of a plastic piece connected to a hose.
The contact owns a 2006 Mercedes Benz E55. The contact stated that after refueling the vehicle, he could smell gasoline inside the cabin of the vehicle. The vehicle was taken to an independent mechanic for diagnosis and the contact was informed that the fuel tank seals would need to be replaced. In the process of replacing the seals, the mechanic discovered that the fuel pump was also cracked. The fuel pump was not replaced and after the repair, the failure recurred. The manufacturer was notified but offered no assistance. The failure and current mileage was 32,000.
I came outside to my car and could not get it to start. The car would crank but would not turn on. Had the car towed to the local mercedes dealership (euro motorcars in germantown, MD). I was told that the fuel pump was leaking and that the fuel shorted the connector that turns the fuel pump on. I googled the problem online to see if it was a common issue, and it seems as if many people have this issue and mercedes already performed a recall on these cars to take care of this problem. I confirmed with the dealer that the recall was done to my vehicle and it was.
Reference NHTSA action # pe12001. After refueling car, interior would have an overwhelming smell of gasoline after leaving it parked. Investigation revealed fuel pooled up underneath rear passenger seat and required replacement of fuel pump.
