Ever since I have had the car, the iDrive controller back button was chipped (doesn't show up in the pictures but it looks worse in person) and the scroll action quite sticky. When I bought the CIC system retrofit setup, it unfortunately came with a very poor condition controller. The rubber grip ring on the controller eventually came loose and wouldn't stay on, so I decided to buy a fresh controller. These are in reasonably high demand, so theyre not particularly cheap. I eventually found one in great condition and with the updated 'media' button instead of the 'cd' button.
Only downside to the controller (which I didn't realize when I bought it) was that it had chrome trims instead of matte silver. Nothing else in my interior has chrome in it (all matte or brushed silver). Luckily the trims are easily removed, just grip the outer chrome controller ring and it comes out. Then the larger chrome piece behind the knob can be unclipped and removed.
Feels good to finally have a fresh controller
