Anyway, I had one of these in the garage from another car I stripped for parts - which showed a 05 date code and generally looked fresher than mine.
I fitted it today (complete with the PCV heater) - and suddenly no further issues!!

Well that was short lived.
Last weekend there were no faults, no matter how hard I tried to provoke it.
Now we're back to the 'Engine Service Required' when booted and ECM-6805.
It's odd that it can be fine, then re-appear. I expect the turbo was HOT last week after several 'enthusiastic' drives, so maybe the VNT is sticking when cooler.
I'll blank off the engine mounts again to confirm that is (still) not related. There were no vacuum leaks anywhere when I checked last week with a mitty gauge.
May need to give in and remove the turbo to inspect it.
