One problem related to other fuel system tank assembly has been reported for the 2009 Mercedes Benz E63. The most recently reported issues are listed below.
Fuel leaking from fuel sending unit and puddling on top of tank. My whole garage is full of fuel vapor! not to mention if it contacted a hot part on the car. I just found out this is a "known issue".
