yes, they're not expensive even on new W211 models.

taek, did you open both tanks? does it happen on full tank too? maybe fuel pump problem already. observe the level while the engine is running...do not close the tank yet.

 

I appreciate all the suggestions and hope they will soon lead to a solution to my fuel cut-off problem.
I intend to fix the prolem by myself, and the instructions will be of tremenduous help.
Thank you.

 

if you will go back to the top and read again, you will find that SL600_Cruzin have already posted the instructions. and even the special tool that you may need to use!

 

i tried to open the two white caps which is located under the rear seat.full of fuel in the both tank.
i checked all the fuses and relays.everythings fine.is it have to reprograme by star diagnostic after changing the pump?

 

Dear All,

I do have the problem with my Mercedes Benz C280 w202 V6, the engine cut off when the fuel gauge reaches half, it initially start at quarter and now its on half. I stuck on the road twice.I replaced the fuel pump for the left side tank(pass side)and the fuel was full in that tank, i removed it and replace the part and refill back but the problem still persist as i stuck again after replacing the fuel pump,
I don't know what to do now, please help what is exactly the problem

thank you for your assistance
