c220 Auto Diesel

[BarrysMerc]

Hi, I bought a 1995 Merc c220 automatic diesel about a year ago, and I have been fairly happy with it.

But recently when I turn the key and wait for the glow lamp indicator to go out and then turn the engine on, the engine starts and then cuts off after 1-2 seconds.

If I rev the engine (above 2500 RPM) the engine does not cut off.
Once I revved the engine and then the "EDC" light came on while the engine was on.

However each time I do wait for the glow lamp indictaor to go out.

I have recently had the oil changed, and new oil+fuel filters put in.

Could this be caused by a faulty glow plug? Or is their a possible problem with the injection system?

Any help much appreciated.

Here in the USA we don't have that car, BUT the E300D that we have has the same or similar problems. The o-rings on the plastic fuel lines will allow air to bypass & then the engine sucks air instead of fuel.

Thankyou M.B.DOC for the reply.

Is it a case of simply replacing the o-rings on the plastic fuel lines.

If so what type of o-rings should be used as replacement (e.g. the same ones or plastic or any other).

Is this a big and expensive job, and have you found that this resolves the problem in all cases?

Many Thanks

It is faster and more cost effective to replace the plastic lines besides, they have a tendency to shrink in length. As well, you would'nt want to break one and leave the car stranded until you recieved the replacment as I had to??? Order all the lines asscosiated with the fuel system at/near/on the injection pump and filter areas.

PS. Order a new o-ring for the prefilter as well
