quattro Digest, Vol 7, Issue 87 - Knock Sensor or Timing Sensor

[l.leung at juno.com]

Both knock sensor replacements are identical (they 
are only availible in the longer cable length). If
you end up with extra cable just coil it carefully 
and tie it up out of the way. BTDT on an MC2 dual
knock sensor car.

Some MC engines have two knock sensors. If the parts people
say there is only one part number, chances are Audi used the
same part to test for knock on different areas of the engine.
(And if I'm wrong, someone please speak up.)
