The "closed loop" nature of the FSI's engine software may not be compatible with EGR mods.Thanks guys.
Coil packs are Bosch and less than 2 years old. Swapped around previously and code stayed on the same cylinder.
I did have the actuator for the flaps replace in 2018 due to a broken rod. At the time the flaps were quite clean and working correctly, but that was about 40k miles ago. I'll take a look a measuring block 142 when I next get time to pick this up again.
Should the flap be closed at lower rpm? I think this could be worth a look.
Another possible curveball, and something I forgot. A year or so ago I noticed that the EGR pipe had a leak. At the time I blanked this using a blanking plate for a Renault that allowed for movement of the EGR valve. I'm wondering whether I've got an air leak here, my thinking being EGR could be closed at idle but then opens under load allowing unmetered air in. Will also look more closely at that maybe see what there is in VAGCOM to get data for the EGR operation.
