I have an 09 M8 with turbo that after rebuilding the motor last year started Blinking ECU code 21 " Knock sensor failure". Traced all the wires, can't find any issues. Changed the knock sensor, Didn't help. Wiring harness is over $400 so need to do more diagnosing before replacing.
Looking to maybe put my computer into someone elses sled and see if it does the same thing. Mine, within 10 seconds will start flashing ECU 21. So would be pretty quick to check.
I live in Avon, co and will to travel to summit county or glenwood?
If you can help in anyway call, PM or post here.
Thanks
