A bit of a strange one this, I've recently had the steering rack replaced on my E92 with one off an accident damaged car. After having the alignment done all appeared to be fine until I realised the buttons on the steering wheel have stopped working (phone, radio, volume etc). Not even lighting up when you put the head lights on which means zero power although the horn does work. Surely this cant be related to the replaced rack can it? I cant see why it would be, the coincidence of something else breaking at the time of the rack being replaced is ridiculous. Any help/advice would be greatly appreciated.
