2014 E350 Fuel Smell When Tank Full
Hi All,
So we have a 2014 E350 sedan and lately have noticed that when the tank is completely full and parking inside we can smell gas in the garage. However, there is no smell in the vehicle as far as I can tell. This issue only happens when the tank is full and after about a gallon is gone it doesn't happen. My indy checked the fuel senders and covers but said they are bone dry and no sign of leaking or pooling as they are clean as well and not discolored. Has anyone else experienced this? As well, I've always thought the fuel gauge has been incorrect the readings, but the multiple times I took to the dealers they never found an issue.

Your indy specialist did the right thing about checking for broken plastic tank covers.
Since this condition only happens with tank full, that reminds me about the decal :
"DO NOT TOP-OFF FUEL TANKS".
I would check your charcoal EVAP canister is not flooded with gasoline.
Drive around a little to use up gas and dry EVAP canister.
This is a common issue on the 211, but also carries over to the W212. Check Senior Leigh. I believe the fuel tank filter is cracked and needs to be replaced.
Remove the rear seat cushion and inspect the filter.

Don't overfilling tank... all good?
When I fill up once it clicks the gas pump handle I take it out. I will have them check the charcoal EVAP canister.

Also, I noticed these metal shavings in my fuel filler neck as well what seems to be a crack in the lining when I was filling up last time. What could cause this?
Just stumbled upon this thread because I noticed the same issue. I found a bunch of metal shavings in the fuel filler neck. This is a 2013 W212 E350 gas with about 110k miles. I just recently acquired the car. I am assuming that it has something to do with metal on metal with the gas cap? I suspect there is a coarse filter on the gas tank fuel pump and a much more robust filter between the gas tank pump and the high pressure fuel pump (I assume this car has one as it is direct injection) that would deal with these metal shavings. Those shavings would definitely kill injectors or HPFP if they made it there.
I think this thread us about the fuel tank SEAL being pressurized and leaking smell outside.
The shavings you saw may be partly normal. I would keep that in mind but not loose anytime with this.
Does your car from outside smell like gasoline ??

Apologies. Completely forgot to give an update. I filled up the tank to the max level when it clicks off the pump right down the street from my mechanics and drove right over. They let it sit for about a hour and then checked the fuel covers under the back seats and indeed one of the fuel tank covers had a very small crack and was seeping a bit of fuel. They replaced with part number 2044700438. No issues since.
Hello everyone, came in here with the same consequences but a slightly different root problem as I understand so far. Today I went to my car and noticed some spot near rear passenger side wheel, seemed to me as a gas. It was a gas leaking coming from evap canister to a cloth wheel house liner.
I do not have any scan diagnostic tool just no check what is going on in the ECU but it definetely seems to me that somewhere on the canister is a gas leak. Probably, the issue is with some connection, maybe seal. Have to discover more tomorrow when I'll try to remove a hose just to pull out that bad boy. The OEM part # is A2044700659.
One more thing, when I opened the tank cap I could hear some noise like air was coming out for some time.
I've made some research but couldn't find gas leaking issue reffered to a evap canister.
If you have any thoughts on this, please let me know.
