Been looking at some A4's, and I have noticed some cars have silver knobs on the head units and some have the regular black ones. I am talking about the previous generation head units, not the new double din ones.
So I would imagine this marked a slight change during model manufacture weeks, so are there any other slight changes to the car. As I know the A3 changed some of the functions in the DIS, ie they started to incorporate a digital speedo in it. Did they ever change the DIS functions on an A4 or any other random changes!?!?
