Yes there was a thread about it a couple of weeks ago, same thing.

When you fitted the new one did you torque it, needs to be 26nm if my memory serves me right, if you just cranked it up as tight as you could then it's possible you broke it, also check the connector and wires.

Also make sure both faces are nice and clean using fine sand paper or wire wool.

I was going to say to clean it because i had the same issue about 3 weeks ago, changed the knock sensor and the light came back again after about 10-15 miles, cleaned it and its spot on.
