Not to sound like a broken record but i am in the same boat.
If you look at the wheel and think of its full turning circle, these clicks happen all over the place and different times on different angles, no consistency at all.
Whilst having my car looked at for no ABS warning message i planned to ask them to have a look at it, but as i parked in their car park i tested myself and all the clicks disappeared and they found nothing wrong with it. That was last week, today i drove whilst it was -4C and it was much worse than ever.
Listening to clicking steering, clunking noise from gear change, irritating vibration from overhead panel and small rough engine sound under acceleration that developed since service did depress me and got me wondering what car to get next year.
