I believe there is a known issue with the 4 cyclinder D4 engines

EGR cooler is prone to blocking.
I believe it doesn't happen if you run it on the super diesel - VPower, Ultimate, etc - HJ

Also see here for examples

So D4 engine is good but needs a little looking after to avoid problems?

As said by others, I keep to the D5, little more power, little thirstier, 5 cyclinder engine note, proven design for the most part.
