In addition to the sensor and cables, it might be worth checking the engine control unit (ECU) and related wiring to ensure there are no issues impacting the knock sensor's functionality.

I just signed up to the forum and saw this thread, but no solution to the problem. Figured I would weigh in as I'm a tech at a BMW dealer and have encountered this problem twice. Both times BMW had pinched the wires leading to the knock sensor during assembly at the factory. Ive only seen this issue on the F850 ADV models and in both cases the wires were pinched behind the left side crash bar (the front bolt that's toughest to access). Was this what the dealership said it was when you took the bike back?

What did you do next to solve this problem?

Jdorazio1668:
Had to loosen the engine guard then pull the smashed wire or wires out, then repair them. There's enough length on the existing harness to cut the damaged part of the wire off then add a quality electrical connector of your choice then heat shrink over it once it's crimped. I chose to use one of those circular "barrel" shaped connector but other types will work as well.
