Yes, I remember you saying you had a number of issues. I forgot one more... When the car first started up, the power steering motor took a few seconds to warm up. If you immediately backed out of a stop (turning)... There was an occasional vibration. Once the car was warm, the issue would not appear again.
All of these issues never caused us a problem, but I wasn't excited to find out post warranty. Luckily A4's have a pretty good resale in our area and we really had kept the car pristine.
I am jealous of you as I would love to be slinging around a new 3-Series... Just doesn't make any sense given out current needs. The 4Rumner has its own charms... but they do not involve driving pleasure or speed. I miss my old M3 even more than the A4 with respect to actually driving.
