So my motor is back in and ista now finds it and four fault codes are in its memory with none currently active.
The one bolt was easy enough to nip up with just my finger and thumb but the one nearest the steering wheel was just as difficult to nip up as it was to get out but I managed it.
I will say if it hasn't been mentioned before that it is far easier to install the ring to the motor before you try to fit the motor to the column as I could not get it to sit right on the motor and had to take it out and start again once I did that the holes lined up and it was straight forward.
Thank you enuff_zed for the info for removing and fitting, I don't think it would have been so straightforward doing it without the knowledge you provided and hopefully the next person with my issue finds this thread just as useful for them.
Just need some decent weather and I can take it out for a test drive.
