Mercedes Benz CLS550 owners have reported 2 problems related to tank assembly (under the gasoline fuel system category). The most recently reported issues are listed below.
When I fill my vehicle up with gas, the fumes fill up my car and my garage. After I drive my car and the gas goes down to 3/4 a tank, the fumes reside. I can only fill my car up 3/4 of a way without the fumes entering my car. I took my car to the dealership and they removed the back seat and saw that the gas was filling up under the seat. They found a leak at the fuel gauge sending unit. The sending unit needs to be replaced.
