Thanks guys !

I have found a local source for the knock sensor Volksbard - $165 for Bosch part number: 0 261 231 077 (which is the aftermarket part number for my car)

I have found a shop in the US that will sell it for $55.91 USD + shipping.

I intend to get this in the next week or so...

Also thanks for the Knock Sensor torque settings... I will try this out as well...

Gee... (i really need to get a manual !)

Cheers
