Hey All - Bought a CPO 13 A4 and been loving it the last 6 months. Been noticing a few weird things that don't seem normal. Was hoping you guys would be able to advise

1) when i turn my steering wheel right, i get a high pitched whine - Almost like a metal on metal pitch - will check the steering fluid to see if everything is good again, but last i checked it seemed ok

2) Noticed a little notchiness in the steering the other night for the first time... i.e. turning the wheel wasn't smooth and almost clicked. It went away after a few minutes

3) Sometime my car clicks behind the dash. It happens mostly when its cold and goes away eventually. I used to have a b5.5 passat and its the same clicking noise that i would get when i would let go of the brake when my gear was in park... not sure how to describe this
