It feels external like wiring or whatever sensors the XM uses for determine which gear since no gear shift.
Were it me I'd probably borrow a gear request knob from a compatible car. Mine came from a different e70 as mine failed. The one i got from my wife's prev car alao e70 was not original. They are not uncommon to fail.
See what Chat GPT had to say. I'll add to the chat if you get me more feedback.
