Chris Hogg laid this down on his screen :
Because of the hotter
combustion temperatures, diesels emit more NOx, which seems to be the

Partially solved at low engine speeds by an EGR, problem is that the
EGR's on a diesel need to be regularly cleaned out and no manufacturer
has them on their service list to be cleaned. The net result is a diesel
engine with a choked up intake system.

That's at least one on my breakdowns explained. Dunno why they swapped
it a second time after 2000 miles on a different breakdown.

Next time get them to blank it off.
