So I did the crystal iDrive controller conversion. After putting everything back together, the lights on the controller knob itself flashed, but never turned back on.

The next day the haptic feedback on the shortcut buttons stopped working. A few days later the tilt functions on the knob stopped working. THEN a few days later the lights on the shortcut buttons stopped working.

The shortcut buttons still work, but no lights at night or vibration on press. The rotation, click (press to select), and touchpad on the iDrive controller all still work fine as well.

I've been doing some research over the past few weeks when I've had time, but I've found nothing helpful. Anyone know what the issue could be or have something that can point me in the right direction?

I've also researched instructions on how to replace the controller module. I've found the part, but can't find any instructions on how to actually do the replacement.

Any help is greatly appreciated!
