Thats very bizarre if they did. Access to the rack bolts from underneath is a piece of cake on the lhd manual, and is a 3 hour job including biscuit breaks. I dread to think what they would have done faced with a rhd auto where you can't even see the rack from underneath!
I think I have the funky lower bolt for a manual. I'll try and find it later and get a pic so you can copy it, otherwise it'll be a scribble from memory! There's nothing on Google Images or Audi Tradition.
There isn't a sequence so just stick the loose bolt back in and tighten to two white knuckes
