Yeah, its the sensor mate
There is no code for actual knock (hence the use of det cans ect), the sensor detects knock then retards/advances the ingition via the ecu

right cheers for that mate, re set it all again and no error codes have come up now (took a bit of a drive to get the cel light to start flashing good). think its a bit strange but when i started it yesterday it did seam to take a bit longer and may of miss fired for a second
anyway ive got my old sensors off the old engine in garage, i will change it and see
just glad you said it dosent sense knock and light up
