Japanese engineer #1: "Which rotor for the knock sensor?"
Japanese engineer #2: "You toss the coin, I'll call it..."
Seriously, I'm sure they had a good reason, I just don't know what it is. The knock sensor is pretty much useless over ~4000rpm because there's too much other noise for it to be able to differentiate knocking. It's mainly there to detect knocking caused by lugging the engine at lower revs. Perhaps under those conditions it's the front rotor that's more susceptible to knock.

wrong answer.
It's there because you have an s4.
If you had an s5, it would be in the center housing.

So, out of curiousity, what would happen, given the Knock Sensor does It's thing when "knocking" occurs?

If you want to verify it works throw a timing light on the car and hit the housing with a hammer (lightly...
). It should retard timing.
