After my engine was rebuilt (long story but cam chain broke and bent valves, valve guides were out of spec so head was replaced and crank reground with new main bearings due to excessive wear) my knock sensor would set off the engine light every time I rode it. BMW NA says the knock sensor detects an actual noise, vibration or resonance frequency not detonation or "knock" as we know it. Bike ran great, no ping, no overheating, etc. Dealer spent $3500 trying to figure it out and could not. They thought it was the clutch basket but it was not. BMW NA could care less because bike was out of factory warranty. There was another bike in my region with a similar problem but to my knowledge it never got rectified either. Never did figure it out so I sold it cheap to someone with more patience. I was probably burnt out after waiting 13 months to get it right. Good Luck, keep us posted!
