I wouldn't call it "sticky" steering like the pre facelift roadsters had it was more of a loose feel. All mechanical parts replaced but was still there. Moved the ring about 10mm and it feels much better. I believe the OP was a Coupe too.

Even if you're unsure, it's a 30 min job (with the right tools) so worth a punt anyway.

Yay! Managed to get bolts loose with a couple of new tools!
So, I have left-hand drive car, and when I’m sitting in the driver’s seat, the motor is to the left of the steering column. Looking up under the column from the footwell, I can see both shoulders of the adjustment ring facing downwards. Anyone know which one to push upwards on to tighten - the one nearest to me (back of car) or the one furthest (front of car)?

Did mine this morning with an 8mm ratchet spanner, moved the ring approx 10mm with my fingers. Let’s hope that cures the sticky steering I’ve always had on a long run.

10mm may be a little bit much in my experience.. I normally start with 5 and see how it goes, too much can introduce play and it then feels weird when the motor starts to spin. The ratchet spanner does make the job easier though doesn't it?

Hmmm this is interesting.
Almost all the time I've had the car I've had an occasional feint knock/rattle on rough gravelly farm type tracks.
It also does it on those sharp edged block type speed bumps.
I've never noticed significant wandering at speed, but it's not what I'd call super planted either.
I just had insp2 and asked specifically about rack looseness (again and again over the years) and it was deemed solid.
This is interesting because the looseness is between the 'assistance' and rack, not in the steering connection itself.
I'm very tempted to tighten mine 3mm and see if the rattly noise goes away and higher speed solidity improves.
On a related note. My new F30 steering has a loud knock from the steering when the car is off. But there is clearly no play.
It goes away once it's started. I heard the techs mentioning electro magnetic something or other.
I'm wondering if the newer EPS have a system that simply pulls the gears tight during operation to a desired force, so removing/reducing any issues with thermals, wear over time etc.

Just been playing with mine (my car, that is). On left-hand drive car it is counterclockwise to tighten (same as for right-hand drive), looking at the front of the motor, as in original pics.
Initial testing seems to show that tightening a bit has fixed the twitchiness at 70 mph. Pretty pleased with the result! Thanks so much, OP!

Drove my car for a week after moving the adjuster approx 10mm, think that’s too much!! As it was a lot stiffer. So I have adjusted it back by 5mm and much nicer drive

This is for right hand drive models
Right had another play with this, originally moved it 10mm towards the pedals which made the steering heavy and guessing reduced power steering input, moved it back 5mm and still had sticky steering, after reading the TIS manual i moved it 5mm the other way from the original setup and what a difference, no sticky steering
