call local MB and they gave me the following for my 06 now:

211-470-45-94 passenger
211-470-49-94 drivers
211-471-05-79 seal rings

go figure. Don't think it could be more confusing with all these part numbers.

So, looking at site after site to get parts for my 06 E55 in another country... Of all of them... including MB fort Lauderdale, autohausaz, partsgeek... I got the best price so far from:

https://mercedespartscenter.com/index.cfm

This is my shopping cart for the following part numbers, total is $828.16 for both drivers and passenger's sending units and O rings. Think anyone know of a place which can do better? Thanks.

211-470-45-94 passenger
211-470-49-94 drivers
211-471-05-79 seal rings

Hopefully the parts u ordered are the latest and greatest design for the fuel units.

Hello, revisiting this thread after a long wait, not browsed the whole of it yet, but trying to find a few simple answers if someone can past the posts or lead me in the right direction. My 06 CLS is having the leaky sender problem, has for a while. I tried what someone else did and used a sealant around the top of the sender to see if it would stop the leak, but no, it didn't. Now it's leading to my check engine light illumination, as slight emissions leak, I'm quit sure it's the leaking sender. Anyway, only the drivers side is leaking (didn't know there was another, is there?) My question is, is replacing the sender easy? like unscrewing it from top or do I have to lower the gas tank and get at something else? I see the parts list someone posted, so, I know where to get the parts, just want to make sure about the replacement procedure. A good DITY would be nice. =0) Thanks.

there is another post of a DIY for replacing the sender units. If you do attempt, i would make sure that there is less than 1/4 tank of gas. You will need to disconnect the wire connectors that are inside the tank itself the ds from the ps side, and make sure the orientation of the units are the same taken out/put back into place.

and check the relay and loom

Just filed my complaint. DS sender is weeping fuel. parts should be in Monday.

Did you order from Mercedespartscenter.com? Looks like cheapest I've found so far. I've not yet ordered anything, but want to.

No I get a discount at the Stealership. So it came out ot be 440.00. I had to pick up a few other things I had on order so it was easier. Had to order the passenger side as well when is seen the plug was melted on three of the leads.

Copterguy pm'd you one of the diy I'll be using when I change mine out this week. If I can ad any tips I'll pm those to you as well.

Thanks
 

Many thanks, hope it goes well and is reaaal easy.

Changing out the sending unit's is fairly easy but time consuming. The first tank the fuel gauge was slightly off but after you fill it back up it seems to calibrate it's self and run true.

Where is that part of the loom located?

My dealer gave me different part numbers, what's the difference?

211-470-51-94
211-470-17-94

Anyone know the correct time to do only the drivers side fuel sender unit?

Mercedes calls for replacement at 60,000 miles.

Sorry, I meant labor rate from alldata. What should it cost just for one side

Part is $505 list. I'd suspect labor to be 1.5-2 hours.

I figured that, I just wish I had something on alldata to prove it

Do it yourself...not a big deal at all.

It's too late now, I got the dealer price at $430. But they're trying to charge me $400 for labor, what's usually the hourly rate and the correct labor time for this job

how would I know if Im eligible for recall? Im third owner of my 2003 E55

makes me wanna keep a fire extinguisher in the car... even though its always good to have one whether or not your vehicle has a recall :).

I don't think there's actually been a recall. If there was, I've got a nice expensive bill to send them.

What have you repaired?

Ive only smelled gas outside of the car, its not very strong and I had a full tank after getting home from a long drive in 95 farenheit miami weather

The pulse dampener on the back of the fuel rail has an o-ring that goes bad. Pop the hood and sniff the back of the motor.
