Hey, I have the same problem with my 91 TT at the moment. I've tried everything as well as a new knock sensor and wiring, but that didn't fix it. I have also wired in a 1 mega ohm resistor and that didn't fix it. So I have also got to the point of blaming it on the ECU. I think I'll soon be switching from JWT to ASHSpec, and see if that works, was going to do that anyway.
