Tank Mounting Problems of Mercedes Benz E350

In 2012 the car began having a strong fuel odor after fill-up that went away once the tank was down to a half to 3/4 full. Took to dealer and they said the "fuel tank was leaking at plastic mounting weld". I was charged to replace the fuel tank. Now the smell is starting to come back again, so the problem appears to be coming back. I did a google search on this issue and it appears many others are having this same problem and you are investigating.

The contact owns a 2006 Mercedes Benz E350. The contact stated that after refueling the vehicle, a strong odor of gasoline was emitted. The odor would dissipate once the amount of fuel within the tank dropped below three-quarters full. The vehicle was taken to an authorized dealer where the fuel tank was lowered. The failure continued. The vehicle was taken back to the dealer where the contact was informed that there was a faulty gasket on the fuel sending unit. The gasket was replaced, but the failure continued. The vehicle was not taken back to be repaired a third time. The manufacturer was not made aware of the failure. The failure mileage was 40,000.
