Hello, After number of trips to the mechanic and trying everything as far as I can understand, I am now writing to the enthusiasts here to help me with their experience and knowledge. I have a C220 CDI sports coupe 2002 version. History: I got couple of injectors and glow plugs changed few months ago. Car was running brilliant. However, I noticed few weeks ago that whenever I used to park the car on a gradient, the car used to start up fine, with the least crank up. But if i parked it on a flat road overnight, I had to crank up a lot. Eventually, the car started to indicate battery/alternator issue. Since I already read a few posts regarding this, I knew that the problem could be regarding air/pressure leakage in the fuel pipes. I took the car to my mechanic a week ago where in we found that there is a fuel leakage in the pipes as shown in picture 1. I got all the fuel pipes replaced as the mechanic suggested. Currently: The mechanic fitted all the pipes yesterday. We tried starting the car but failed. The battery went dead as the car was idle for a week. We tried checking fault codes but his computer didn't show up any. He tried checking the pressure on the long pipe connected to the injectors (not sure if it's a fuel rail - i don't know). The pressure at certain areas showed 0.4 He always sprayed something in one of the big black hose. The car started for few seconds but it just died again. Please can you suggest what could be the issue and where can we begin to get this started now? PS: I am not quite sure of certain parts that you might point out, so it would be great if you can help me with bit of a description/location of the part or a picture. Thanks, Vish.
