39 problems related to other fuel system have been reported for the 2005 Mercedes Benz E320. The most recently reported issues are listed below.
Noticed a strong gasoline odor emanating from the rear of the car. On further investigation, I discovered that there was fuel pooling underneath the drivers side back seat and that two electrical wires were submerged in the fuel collecting underneath the seat. The fuel originated from a crack near the top of the fuel sending unit. This is a potential fire hazard not to mention the significant health issues to all passengers including the nine year old that is transported in this vehicle. This is a known issue and should be thoroughly investigated.
About a year ago, we noticed a mild gas smell after fill up. The smell used to go away in a matter of hours, so we attributed that to possible spill during refill. Gradually, smell became stronger and lasted longer. Early January 2013, after a recent fill up, we stored the car in garage for 2 weeks while using our other vehicle. The smell became so strong, it was felt in laundry room next to the garage. Smell wouldn't go away so we suspected a gas leak. Upon examination by dealer, it was found that there is significant gas leak under rear seat (passenger side). The leak was from a defective fuel filter and sender unit. We found out that this is a very common defect with 2005 E320 class cars. Indeed manufacturer had issued a recall in 2008 covering leaking fuel filters. The recall included 2005 E320 but apparently did not include my vehicle. This is a serious safety/health hazard that should have been addressed by the manufacturer.
Strong odor of fuel inside and outside vehicle, specifically after refueling. Leak visible under rear seats and leakage outside vehicle.
