Hello Norway here.
I got me a Mercedes Benz 2010 mod w221 S 400 hybrid from USA
The prob is when I filling gasoline it stop quit often. I fill and stop ..filling and stop...So its take a very long time to fill gasoline... It's like the thank is full but its not. They try on the car workshop here in Norway to fiks but they can not fine out what is wrong. The diagnose said its something about gasoline air when filling.
They try to contact Germany but they thinking its because the gasoline ait wont come out when filling
Please hope someone can get us an ide whats wrong.
Thank you.

 

Does it hiss when you open the cap?

Possibly a blocked tank vent or charcoal canister or associated plumbing.

Presumably it was drained for shipping, but possibly something was dislodged on the way over the pond or damaged during preparation.

 

Thank you..
No when I open the cap it dont hear that air come out. It was one time when it was filling all up from the dealer shop when I got the car. But no more..
I can let the car garage see what you have written..
This car was taken inn to Norway in 2018. So why stop now ?
It seems that it was happening now in 2025... 7 years later..
Maybe a filter??

 

I'm guessing it is the charcoal filter in the rear right wheel well. They are about $375 in the US. A scan might point you in the right direction though.

 

I presumed, because you started about it being imported, that it was a recent import.

Charcoal canister/vapour recovery system or blocked vent pipe are the still the two most likely culprits. Purge valves can also fail.

 

No I just buy it and things are getting up. And I like to tell the people here who dont know what it is that you are thinking. The people who are working in the car garage have not seen this gasoline prob.

 

I will tell them what you are gessing so they in the car garage can lock att it.

 

It is almost assuredly the charcoal canister in the wheel well. Typically, some moron over fills the tank. They try to squeeze in as much fuel as they can. The problem is that extra fuel gets sucked up by the charcoal canister and it floods with fuel. It is only designed to work with emissions (vapors) and when flooded, it acts as a block or obstacle. We have heard of people who dismantle the canister and dry it out (don't use an oven to dry it for obvious fuel related fires); but it is not expensive and is readily available at a Mercedes dealer or parts store. Keep us posted.

 

Thank you. When I got the car the dealer had fill it up to the top. And he had the car for a year. So when I buy it many it was broken thats why he fill the thank up so I did thing it was my foul.. I will let the car garage see what you Wright.. thank you..

 

european filling is a bit different to USA pumps

some cars that keep cutting the pumps out - tend to be model by model (design flaw), rather than one w221 is OK and another isn't
that said try to rotate the pump handle and nozzel 30 degrees or so and see if it works - some cars do behave a bit stupid but that trick should get you passed it

my father's E class tractor is exactly like this - I have never considered it an issues as I just tweak the rotation till it fills flat out - but my sister couldn't fill it up at all and thought the car was faulty...

 

Thank you for your answer but I have tried that to turn the pump handle but it did'nt work out..
I know some have done that but not for my w221...

 

Wouldn't hurt to replace other parts of the emissions system as well. Parts are still available, and not very expensive. Before your shop spends hours billing you looking for a problem, I'd suggest you just go ahead and get a canister coming--you might end up saving yourself a couple hours of diagnostic time which would cost more than the part. Even if the canister is not the culprit (which it likely is), it is near the end of its useful life anyway and replacing it would not hurt. BTW, heading to your country soon--Alta.

 

Anyone able to pull up a pic of all the fuel and vapor lines at the tank in WIS for this nice lady?

I don’t know how similar the vapor system is in the 221 vs 211 but the 211 had a valve that opened up to let vapors out when filling the tank. It failed for exactly the complaint OP describes. Happened in my E-55 for 20+ minute fillips until it arrived at MB.

 

can't speak for strange emission stuff - euro spec cars and bikes don't have the charcoal canister time wasting pretend helping hand USA mandate

but years back they did mandate anti tamper siphoning - so there is a pathetic metal flap that is only meant to open when a correct sized nozzle is in the tank - theses days many like to pretend its an anti spill device when the car is on its roof, but the cap is there and 100% stops that happening - either way this pathetic metal flap does stop the uninitiated triggering the flap release with a small screwdriver - so without you can't easily get a hose in the filler neck to suck fuel out

if some halfwit has molested the anti siphon flap this often causes filling issues at the pump

 

This thread helped me a lot: https://mbworld.org/forums/s-class-w...problem-2.html

 

Can someone give me the number on the charcoal filter www 221 .......Pleace so we many can find it here in Norway..??

 

It's quite expensive. Just clean it. This is the part number: A2214700659.

 

Thank you . I have fine another car garage and hope they can find out and ..
Thank you

 

This dealer has consistently good prices...https://www.mbpartsource.com/oem-par...bC12OC1nYXM%3D

 

Well not in Norway.. Here it cost 1092,09 usd.. And the garage will charge me about 700 usd just to replace it... Norway is very expensive country when it comes to cars...

 

I have this problem at very fast pumps. When it happens I pull the nozzle out a little and so far it has always worked.

 

30 seconds on Google found in in Latvia... New for €500.

And I am currently in Houston so no search bias.

And I pretty much guarantee that your local Merc dealer will beat that.

 

You may be able to solve this problem without purchasing a new charcoal canister. Try this instead: Remove the solenoid at the top of the canister. Clean the solenoid, the foam sleeve, and the flat filter just below the solenoid. I had the problem of gas pump clicking off for 3+ years; I always assumed it was a design flaw. After cleaning these 3 locations, I filled the tank and the gas pump did not click off a single time (until the tank of appropriately filled). There are others on this forum who did the same thing with same successful result. Cost = $0. Total time to do this is less than about 2 hours.

 

Thank you. I must fine someone who can take a look at it for me.

 

Yes, just clean it, blow it out with compressed air. There isn't much that can go wrong with charcoal canister. The filter screen that sits below the solenoid gets clogged. Vaccuum and blow it out first, then spray brake cleen. Now blow compressed air from the tubes one at a time blocking the other one and see that you get air through that filter. Now bench test solenoid with 12v, Most likely foam on solenoid is bad, just rip it off, mine just shred to pieces. If youres is good, just clean it. Tried filling after this, worked perfect
