W211 Fuel leak issues

Post by ben108 » Mon 16 Jan, 2017 9:33 am

Hi all,

I have read a lot on MB-World about W211's in the US having problems leaking fuel and needing the tank and pump(s) replaced.
A bunch of owners lodged complaints with the "U. S. Department of Transportation National Highway Traffic Safety Administration" who investigated the problem.
The outcome was MB USA extended the warranty on these fuel system components to 15yrs/unlimited mileage. It seems most affected cars get a new tank/pump etc.
No doubt MB only honours this is the US, as they did with the SBC issues.
The report mentions ethanol in fuel as a possible cause, but is inconclusive,

I have not find any mention of this occurring in Australia or Europe.
Has anyone in Australia had any problems with this issue?

Thank!

Never any fuel leak issue with my W211. US ones may have been assembled in Alabama or even Mexico?

Hi, I have an 2004 Model E500 W211 and fuels leaks out of the tank whenever I fill up. Mechanic advised me that it is either the fuel pump or sending unit leaking.

Tilt the back seat up, pull the carpet back and remove the inspection cover over the pump.
You'll quickly see where it's coming from and if you are lucky you maybe able to fix it without buying parts.
It's a much cheaper fix on you car than an E55 :)
