E63 significant fuel smell after filling up.




I remember reading some things that the E55s had something that leaked in their fuel system, and was not sure if the E63 was different, or if this may be related. Any help is appreciated, as I leave tomorrow for a 1,500 mile trip to Canada in this car.
Thank you, and happy holidays.

Good luck on your trip, dont let this get in your head on the way, it's no big deal especially if you dont smell any gas inside...considering you will be in the car for a long period of time.

Do not fill up the car any longer. Keep fuel level under 3/4 level.
The fuel pools on top of the gas tank. This is dangerous. Period
See the many E55 threads with pictures. You have the same design tank and body structure. It will leak inside.
Fill up the car. Go home, take out rear seat, pop off the body covers and inspect the tank and senders. 5 minutes of work.
Take pictures and call NHTSA.

I made an appointment at the Mercedes dealer scheduled for the day after we return to have this fixed. I advised my wife to not fill it up, and if she smells fuel inside the car to take it to the Mercedes dealer near her Mom's house (where we are having Christmas) in Canada immediately.
Thanks for the help though!

If this an out of pocket expense. Take it to an American dealer. The Canadian dealer will not have any idea since they don't use ethanol in their premium gas. Therefore they are less inclined to give discounts like American dealers have.

Ive had this problem for 3+ years and still have not blown up.

Well, I am also getting a faint smell. Also, as the tank gets low, it seems the CEL is going off. (So it seems, need couple more data points).
I will check in the new year and post with pictures.
Could one technically call this part of the emissions system and claim it covered under the 10yr warrantee?
No smell inside the car, just noticeable when going into the garage in then AM.
When the gas tank is full they detected a small puddle of fuel along the outside of the fuel sender/pump units (under reaer passenger seats).
There seems to be an issue with the seal material failing over time.
What brand of gas do you fillup with (Chevron, Shell, Costco)?
Problem never really went away and I just didnt bother to waste another trip to get it fix (even with the free gas). I just filled it 3/4 of a way.. eventually traded it in May of this year for an M3 vert. The M didnt last long as I'm back in another 63.
