I have heard surprisingly little about the latest generation of EcoDiesel. I think the shift to low-pressure EGR (taking an EGR sample post-DPF where there is much less soot) was a wise choice for that engine. The previous generation had loads of issues that I think could be resolved with that move.

I worked on an under-boost diagnostic for the previous generation and learned at that time that low compression right from the factory was something they were plagued with, to the point where the boost response from a stock vehicle with low compression looked like an engine with normal compression and a 4mm hole in a boost hose.

For the trouble we dealt with, I did always enjoy the way the EcoDiesel drove, especially when paired with that 8 speed ZF.

I think I've heard rumblings of CP4 injection pump failures hitting the EcoDiesel now, but that is more of a global problem with all applications running the CP4, not isolated to FCA.
