Boy after reading through this thread, and not expericencing this issue myself (knock on wood)...and after asking my certified MB Indy how many of these he has seen (low)...maybe it would be nice to see a Poll to see how many have ahd the issues, vs. those that have not??

I don't know how to do that...anybody want to set one up? Worth it?

Talked to my MB tech and had him take a peek at it. We're still not 100% on where the leak is coming from. Might be the gasket, might be a crack in the unit, both of which are common. That pump/sender/filter is a maintenance item, that's supposed to be swapped at 65k miles, which I did not do. So, I think I'm just gonna swap it for a new unit to be safe. Since the filter is part of that unit, probably not a bad idea. The R/R on it, shouldn't be too bad.

The filter is built into the assembly and not replaceable on its own? The Germans do a lot of things right, but some things very, very wrong. The filter and pump should have been made to be independently replaceable in my opinion.

Yessur....

All one peice. Really guys, check yours. Even if you don't smell fuel. I promise you, if it takes more than 7 minutes, you need to turn in your man card.

Those of you who had the tank replaced under extended warranty...which warranty companies did you have? I have NAC and they've already paid to replace the sending unit, but the dealer just called to inform me the whole tank needs replacing and they're just waiting on NAC approval.

JlredMB

Ok...really? How many cars do you guys know off (especially of the 100k variety) that have to have a complete friggin gas tank replaced?

This sucks...Come on MB...Man Up!

I replaced mine at my own expense of $1K at the dealer. No assistance whatsoever despite my having been a loyal customer. I even removed the seat for them and showed them how it was leaking fuel around the plastic sending unit. I kept my old part, thinking I could JB weld it and possibly sell it cheaply to someone who is in a bind. Really a poor design, and an even poorer job at my local dealer. They knew I was upset and as a result did not even send me the post repair survey.

Dealer called, NAC adjuster came out and they've authorized my gas tank replacement. Will be interested to see the final invoice.

mine is a 2007 e63 with 117k miles. Just had tank and sending units changed... 3116.76

Just filled the car with gas (first time since the "repair"), the smell is back, now I am pissed, I spent $300 for a new O ring to fix the issue?

moosejaw

By O Ring, I hope you dont mean the Green rubber thing?

Ronan Mc Cabe

By O ring I mean Part Number 211-471-05-79 SEAL RING, which is described as Fuel Sending Unit Seal. I don't know what the "Green rubber thing" is.

I Like Soup

Well, I've noticed that my garage smelled of fuel after I filled up, but it would eventually go away. I'm also having a hesitation issue that came up within the last week or so. Maybe the fuel sender is responsible for both?

Craftysince86

so i been throwing a p0456 code in my 320

i have that intense gas smell at fill up, most likely i assume this is what it would be? are the parts the same for sending unit in all w211? i would assume that the fuel setup might be more intense to compensate for the difference in power plants between the two cars.

but would this cause me to throw this code?

I had my fuel pump replaced the first time when gas was leaking under my backseat. I had the fuel pump AND the gas tank replaced months again for a second time when gas was leaking under my car on the drivers side. Yesterday, My car dies on me while I am on the highway....luckily traffic was not bad and there was a big pullover area. I had it towed to an indy shop.....the shop showed me that it was the fuel pump and the pump break area. They think it was from the pump not properly installed or seated, which is why once in a awhile I would smell gas. I have an extended warranty and the warranty would not pay for a new pump unless the work was done at the dealer. Well, I don't trust the dealer and I want the work done right. So I had the work done at the indy and I paid it myself. I have my kids in the backseat and it pisses me off that I continue to have this problem.

Another reason why I did not want it done at the dealer is because EVERY time I take my car to the dealer the same problem that brought me to dealer comes back a few weeks later. However, this does not happen when I bring it to the Indy shop.

I'll beat the horse again and say FILE A NHTSA REPORT. The fed can and WILL force Mercedes arm on this with enough complaints.

FinanceMike

Both the right and left side fuel sender units are bad on my cls55. My friend who is a Mercedes tech is changing them for me. The part numbers that I was told were 2114705194 and 2114701794.

Does anyone know of an online source to purchase these parts? Even with a discount, the dealership seems expensive.

Thank you

I appreciate it.

theunderlord

haha..

I just googled "mercedes 2114701794" and clicked a few times.


I have no experience with that parts seller at all.

moosejaw

Look at what i found
I think the recall is coming to fruition???



Heres the link...

Do a search for MB E55 with your year and you will see in the pull down menu there is a investigation for the fuel tank and fuel pump assembly.
Ive been told by a reliable source that Mercedes is stocking up on these parts big time
Ive also heard that people who had paid out of pocket before hand will get reimbursed by MBUSA.

Note that NHTSA has not completed their investiagtion yet. So no freebies till they come to a conclusion.
Can anyone else verify this? Or am i dreaming?
This is the one reason I'm contemplating selling my car. I dont want a bomb LOL

moosejaw

I would have thought this would have made bigger news? Should my post be made in its own thread?

theunderlord

good catch! new thread?

CharlyE500

I wonder how much will cost fix it in your own pocket ?
