They don't have issues unless there is an engine management fault.

If we're going to play semantics then bombproof is hardly the correct description either, I don't think it would sustain a direct hit from a B61 nuclear bomb ;-).
The D5 engines have shared the same block, cylinder bore, stroke, turbos, common rail and compression ratios across different generations including 163-185. I'm not saying the DPF is an afterthought or even that it is done badly, what I am saying is that the D4 in it's current iteration was built from scratch to include a DPF. Over the years and even in this forum there has been DPF issues and oil level caused by DPF issues on the D5 highlighted and discussed.
