I love my aftermarket warranty! After 4 days and $1,103.10 in repairs, I only had to pay $148.60 for all factory parts and labor. Left fuel sending unit and some other little tweaks, and I have my baby back.

I had the same issue last year and the dealer fixed it even though my warranty expired.
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)?

im not having any issues, but if this does pop up with my car.. im making the dealer warranty it, or whoever i let fix it so if it comes back they can fix it again.
Well look on the bright side guys.. its a "cheap" fix... compared to other common failures with the E Class.

I had the stupid leak on 6/2011, dealer fixed it at no charge (CPO warrantyt expired). I had the same stupid leak re-occur on 6/2013 (last week) and the dealer fixed it again at no charge. They contacted Mercedes but decided to fix it again free of charge given that it's a gasoline leak.
Whatever is going on with the fuel system, these parts should not be failing every 1-2 years. Totally unacceptable and I am contemplating on keeping this car because of this problem!
This is for those that are R&D/Quality/Manufacturing Engineers in the auto or bio-tech industry, I'm curious as to what Mercedes categorizes their Failure Mode and Effects Analysis (FMEA) Risk Index value? Given that there is no major recall, injuries or deaths, it must be low risk? I would think that anything involving a hazardous combustible fluid leak would be a moderate/high risk item resulting in extensive design verification/validation and process validation.

Looks like I have a fuel pump leak also
Looks like I am replacing my fuel pump assembly this week also. I guess I am lucky that I have the folding seats on my car making access pretty quick.
