Just purchased a high miles 1995 C220 Diesel and, amongst other things, I have what seems like an expensive (i.e. non DIY) problem: the EDC warning light comes on (intermittently) and also the engine revs are sometimes limited to about 3500 RPM. There is no simple correlation as sometimes the revs aren't restricted, at least in neutral, although they are most of the time under load, and the appearance of the EDC light and the engine performance problem are not firmly linked i.e. if the light is off the revs can still be limited. When switching off the engine runs for about 3 seconds before stopping, and cold starting is poor.
I presume that this is a problem that can only be bottomed by specialist diagnostics but if any one has had similar problems I would be interested to hear from you.
Thanks
Chris
