I was fingering through the FSM last night as I was goign to bed telling myself a bedtime story about the rotary engine. Then I came across this chaper in the book that mentioned the knock sensors that are located above the leading sparkplug hole. Well this sparked my curiosity and checked some of the pics I had of my car... there are 2 holes but nothing in them... I have a s5 engine... do I need them? Was I just sleepy and not reading the manual correctly or what?

 

Knock sensors are only on turbo motors

 

Then it was probally my sleepyness....
