The two sensors are fixed to the block under the inlet manifold.

If I remember correctly, I had to reach up from underneath the front nearside of the car (front wheel off) to refit the two plugs onto the knock sensors, when I replaced my wiring loom.

The plugs on the end of the wires will likely just be resting on the sensors I guess (if that is indeed the problem).

Where in the UK are you - I am in Berks - possible to meet up ?
