I'm due to go to a RR day on Saturday with another forum, but the guy who runs it says he had problems running the last S3 on his rollers. Now I know you can remove the Haldex fuse and get it done in fwd only so I have a couple of questions.
a) Which fuse?
b) When the result comes through, I'm guessing that some sort of calculation needs to be made to work out the true figures? This is on the understanding that the Haldex still routes the power but the Haldex clutch simply doesn't engage due to the fuse removal thus the power at the front wheels only isn't 100%?
