An update. I disconnected the EGR plug an fitted a 4.7 K Ohm resistor across the end two pins and then cleared the codes. A ten mile test drive of mixed gentle/hard driving was uneventful with the ETC light staying off and the car not going into limp mode. Checked for codes on my return and found a P0401 and the P0673 #3 glow plug warning, both of which I was expecting.

I think I'll drive it for a bit and see if it is happy to run with the resistor and me clearing the code periodically. If not, I'll have to bite the bullet and replace the EGR .

I'll have a look at the glow plug at the weekend and maybe do the resistor trick on the swirl while I am at it.
