Hi All, I have a funny problem with my W203 270 CDI (2001). I recently broke down, and the fault turned out to be the high pressure fuel pump. I had it replaced, along with the fuel lines as recommended by my local garage (not MB dealer). Since then, they advised that coincidentally the fuel gauge is faulty, and at 1/4 tank the car runs out of fuel. However, when I fill it up, it doesn't take a full tank - there is obviously fuel in there. My gut feeling is there is fuel in there, but it's not getting to the engine. Could it be some sort of air lock or something? I have no idea, but I would like to be able to go back to the garage and tell them what the problem might be so they can fix it. Goodness knows it's cost me enough so far! Thanks in advance for any help, Chris.
