For the self-centering to work, is that whilst driving, with the EPAS power connected ?
Could it be a wheel alignment issue ...?
I think MGF's have some issue with speedo or tacho signals and/or alternator voltage affecting the EPAS...?

Yes, while driving and it makes no difference if the EPAS is active or if the fuse is pulled. It had a 4 wheel alignment 3 weeks ago, the ride height is correct, the front tyres are new.
It's such an annoying problem and makes for a frustrating drive as you're always manually correcting it for the last few degrees either way of central.
The known fault with the EPAS system is that they can sometimes steer left on their own, repositioning the torque sensor cures that.

If you disconnect the track rods from the front arms, then check for any binding or tight spots on both front suspension and the rack itself, I am wondering if it is an issue with one of the swivel joints, especially the lower ones that may have been tightened enforce the vehicle was sitting on the ground.
Or the caster angles are incorrect due to kerb or pothole interaction.

All the steering geometry is within spec, according to the printout.
With the track rods disconnected from the steering arms I can push and pull the rack from lock to lock with no obvious resistance and swivel each wheel freely.
One ball joint felt a bit iffy so I replaced it but the new one was tighter than the old one.

I don't believe so, I asked on a couple of FB groups and nobody said it was a common issue.Might be a silly question, but is it simply a feature of the TF
I wish I wasn't so far into this car, for a £500 buy it's become a bit of a money pit.
I do still enjoy driving it though, despite this niggle. It really is a lot of fun.

I know what you mean about fun to drive. A pal of mine had one and despite it ny being the 135 (04 plate), point to point, it would easily out perform the wifes MX5 (05 plate, 1.8i sport).I don't believe so, I asked on a couple of FB groups and nobody said it was a common issue.

On my diagnostics system it has a steering correction facility, goes through the module and resets the whole PAS. Might be worth plugging it in and seeing if your model has this facility W.

It’s not the PAS Brian, I’ve driven it with the fuse out and it behaves exactly the same.

Bent rack in the steering, not noticeable when it's up in the air and easy to turn with no tyre load but can give issues with centralising and or stickiness on a certain turn noticeable more one way than the other, Has the front had a bump, clouted a kerb or such, wheel damage anywhere? the only real way too tell is with the steering rack disconnected and push it by had through it's length of travel.

From my previous post:
So when sitting in it, trackrod ends disconnected, does the wheel feel tight around the centre point, or is it free? If its tight you could disconnect the rack and try it again, but you have replaced the column...
If all is well and its still tight on the road I would retract my earlier statement and look at the upper balljoints - cheap as chips to replace, that's the thing about these cars - they are a pain in the a**e because something is allways going wrong, but everything is cheap....
Wife had a 135 TF - loads of fun hooligan car, allways needed fixing, some things happened in the cooling system ecu that couldn't be explained though.
I had a 160vvc T hill climb car that I doctored the hydragas suspension, added springs and shocks to the front, gutted interior, petrol tank moved to the front etc, and had plans to convert to rod gear change , fit a turbo etc. Sadly, life got in the way, I scrapped it...

You might want to check the link out it seems the saved tracking settings aren't always correct.

Have you checked the strut top mounts maybe...suspension is difficult to pinpoint as it usually requires loads to produce the fault so might feel fine up in the air with zero load.
