Yup, classic symptoms.
Get the EPS motor out and sent off to ECU Testing for a refurb.
Do it through their eBay site and its a bit less £295.
Depending where you are I've done a few now and happy to help. If too far away then PM me and we can talk through it.

Ah yes, a fair way from the middle of Norfolk then.

Relatively easy if you know your way around a spanner or two.
I take the seat and steering wheel out first as at 58 I am not as bendy as I was and it's easier to lay in the footwell with my head on the pedals.
Lower steering cowl and footwell panel off.
Mark indelibly a line across the motor flange, the spacer and the column. You need this to ensure it reassembles in the right place.
Two torx head bolts hold the motor on. An 8mm ratchet ring spanner fits them well.
Undo those then the motor moves outboard to clear the worm drive. It takes a bit of a wiggle and you need to push the clutch pedal right down with the back of your head to get that extra bit of room.
The big power plug will come out easily before you remove the motor, but the smaller two above it are fiddly and it is easier to lower the motor down so you can see them. One is ty-wrapped to the motor preventing the motor resting on the floor, so have snips handy and take the weight while you clip those off.
Refitting, in the best Haynes manual tradition, is the reverse of removal.

Once the motor is out, find the ECU testing ebay advert:
https://www.ebay.co.uk/itm/401352168863

Buy the service then wait. They will contact you to confirm your email address.
The timeline for me was:
Sunday evening - buy the service on eBay
Monday 0800 - they contacted me to check the email address
Monday 0900 - paid DHL label emailed to me
Monday 1200 - DHL collected the parcel
Tuesday 0730 - text to say the engineer was starting
Tuesday 1000 - text to say the unit was fixed
Wednesday 1200 - DHL returned it!

It comes with a lifetime warranty as well.

As I said, if you want to PM me we can exchange contact details and I can talk you through it.

You are not changing the column, just the motor that powers it. I have a complete column here. I think a WhatsApp video call would help you a lot
