2003 Mercedes-Benz E500 Fuel system Problems

“I smell gas inside my vehicle when I fill up my gas tank and it smells really strong in the car , I took it to mercedes dealership and they said that there was in fact a leak I had pay for them to diagnosis it and they also said it was leaking a little inside the vehicle that they could not fix it and that I had to pay to replace the tank and fuel pump and sending unit .”

“When the tank is full it has a very strong smell of gas inside and around the car for a couple of days, also misfire during these few days. I'm afraid this might cause a serious fire. I would like to hear from Mercedes-Benz asap regarding this possible dangerous issue, any help to correct this matter will be appreciated.”

“Strong smell of gasoline in cabin of vehicle and outside on drivers side after filling up the night prior. The car was not topped off . Online search for cause of this problem found this is common among w211 mercedes vehicles. This car is new to me, this is the first time I fueled the car.”

“I had refueled my vehicle and noticed the presence of gas fumes when I parked in my garage. I always use the auto shutoff at the pump so there was no concern for me to top off something I never do. I notice that if I filled my tank closer to the 3/4 or below level it was not noticeable.”

“I have had this problem for a while now. When I fill up my fuel tank there is a drastic smell of gas. I believe this is a safety issue. I had to leave my car out on the street in fear my water heater when igniting would set off a explosion. I am sure mb knows of this situation since I have seen numerous remarks and instances on just this subject. I would hope that mb will address this problem. I took it to the dealer and indeed they said that the fuel sending unit has a crack on top allowing the fuel to leak when filled up to the full mark. Thank you advance in reporting this to mercedes.”
