Any diesel engine that has SCR and isn't miserly on the urea should be good to go. It's the ones that cheap out and rely excessively on EGR that you should watch out for.
Mine is a citroen so uses a urea system - hopefully good then... It's a lovely family car and easy 53mpg - though as a cyclist and parent I'm now feeling guilty about particulates, but as I say I drive irregularly and mainly motorway miles.
The urea system allows the engine to run lean and hot without excess NOx emissions, which reduces particulate emissions. The particulate filter should take care of the rest.
Great to hear! Pleased that they haven't been drawn into the emissions scandal (so far?) - really hopeful that my next car can be a electric or hybrid - but just have to see how the used car market pans out.
