Still, I feel the OM617 is a bit easier to work on, and is certainly the toughest engine I've ever seen fit in anything commercially available, and that includes the mighty 5.9 Cummins.

Fortunately on the OM602 it's the same glow plugs as the OM617. Issue is that the intake manifold is in the way. I believe you can change them with the intake manifold in place, you just don't have much space. That may not be true on the turbo.
I would like to say in the defense of most Mercedes engines in general is that they are fairly durable. The M103 has its issues but I have seen many examples with over 400K miles. Same for the V8s and most other gas engines. The CIS system I believe is very reliable, it's just difficult to get it functioning 100% perfect if it has been neglected. 190Es are very popular for 24 hours of Lemons and other similar events because they are cheap and hold up well in endurance races.
