The fuse 6 is the diagnostic port its only a 5 amp so it nothing drastic. It was a friend and he decided it was to much of a faff to fix it. Im very handy and have built meany cars from evos subarus, bmw m3, meany golfs, 2 audi s3's but i thought asking if its a common problem would be a good start. If not ill trace it, i quite like wiring anyway.
