I am starting to love them, too! The labor time to change the turbo is a solid 2.5 hours more than the previous cars! Woot!
But we are not done, yet. The DPF alone was a challenge to get out... had to remove the subframe and the right axle, the backside of the engine is an albatross of tubes, wires, hoses, valves, sensors, all jammed into a VERY tight area. This engine is COMPLEX beyond any 4 cylinder I have ever serviced, by far. Let's hope they hold up better than this one has, because working on the engine is NOT going to be pleasant for the novice. 3 fuel pumps, 2 pressure sensors, 2 throttles, 2 EGRs, 3 EGT sensors, 1 lambda sensor, 2 intake paths, 4 pressure-sensing glow plugs, an EGR filter, a DPF, a de-NOx cat, a de-sulfur cat... seriously the backside of this engine reminds me of the Borg Cube.
I am saddened by this CR engine due to the complexity. The performance is good (not any better than the 2.0L PD though), the emissions is outstanding, the quietness of the engine is extraordinary... but it remains to be seen if they have done as good as MB has with these.
Would I buy one myself? Yeah, probably would.

But I think 10 years from now, we will look back and recollect the shortcomings and weaknesses of these early CR engines much the same way we do now about the previous engines. I have confidence in the overall design, though, but the simplicity of a diesel engine is long gone, and it probably won't ever come back.
