No codes are logged. Only 2 years old and just had the 2nd service (25k so far but done since 8k). Filters have been changed, lamda sensor, engine software updated and I have even put redex in regularly in case the injectors are clogging up.

Never used supermarket diesel in it.

I would suspect an EGR... Is it a D4 VEA(4 plot engine ) or the old 5 cylinder?

Yes, all done by a main dealer but they can find nothing wrong.

your dealer should take car out with there lap top and look at parameters see what's a miss

Using plot graphed surprised they haven't done this yet tbh

The car has been with the dealer for over 2 weeks and they are now testing disabling the four wheel drive to make it front wheel drive only as they believe the coupling may be the cause as still no faults found. They have felt the minor power losses and gains but not the larger judders.

Fingers crossed.

It is intermittent but I am not sure how often they have driven it to test it.

Is it under warranty
