missing knock sensor
Greetings from the Black Hills. I have newly aquired a 2000 528i sport with the I6. I have been replacing sensors, and I'm down to the knock sensors. I went to install the new sensors, and I found the harness side recepticle, but no knock sensors! ...anywhere! And this would explain why I keep getting that code. My problem is I have no idea where the mounting points are. I see several threaded female openings on the block, and from the viewing angle I have, I don't see any obvious ones to start with. Having searched the forum for these questions with no luck, I decided to post these 3 questions:
Where are the mounting holes for the two knock sensors?
If I need to remove other components to install the new sensors, is there a DIY thread on here?
Does anyone know the size/thread cut of the mounting bolts? (I'm pretty sure mine are MIA)
Thanks in advance for any beta that can be shared.
