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.
