i was once getting the knock sensor display and diagnostic results...           
until i went into the engine compartment and reconnected the knock              
sensor wire a mechanic had left open.  it's one of the three connectors         
in a "rack" on the firewall near the wastegate.  i think it's the one           
with the red color coding, but check all three (or your bentley.)               
also, i have read that VW 8V knock sensor engines are sticklers about           
having the knock sensor itself properly torqued.  this may also be              
true with the 10V I5's knock sensor.  (good luck getting a torque               
wrench in there!)                                                               

btw, that vaccuum tube on your antenna may be a moisture drain.
