What have you done to fix it? Code 52 (knock sensor circuit fault) is very often due to poor signal and can often be repaired by rewiring with shielded cable and new or cleaned contacts. I believe there's a writeup on it in the MKIII FAQ section.

Ok, it's not in the FAQ. I'll have to add it when I have a chance.
