Two problems related to tank assembly have been reported for the 2007 Mercedes Benz E550. The most recently reported issues are listed below.
When filling the gas tank all the way and stopping the delivery of fuel after the first click there is a strong smell of gasoline when the car is parked (almost like a leak). The smell goes away after the fuel drops below 3/4 of a tank. This happens every time.
This is in reference to NHTSA action number pe12001. Many owners of w211 mercedes products (e-class, model years 2003-2009) report fuel leaks and strong fuel fumes after a filling the tank. I am also experiencing this issue, with the strongest gasoline smell occurring around the driver's-side rear wheel well. This issue is reportedly with either the filler tube, the gasoline tank, or a combination of both parts. Many owners have fixed their issues by replacing both the filler tube and the tank at a cost of around $2000, or less depending on the owner's success in negotiating dealer participation in cost. I am holding off repairing this issue to see if Mercedes Benz initiates a recall based on NHTSA recommendations.
