I doubt hazzydayz would have charged you £300 for supply & fitting, do you mean just to fit it?
Bought mine from Hazy Days £300 fitted.
Yes, they took my wheel in part ex & yes, the price was £300 fitted. I understand that they buy them direct from Germany.
Is there a tutorial anywhere for newbies to code a MF wheel or a RNSE ? A few basic steps to get us started. The download PDF tells us about fault codes and shows you round the basics but nothing on say.....Changing the start screen on a rnse for example.
Is there a list of codes somewhere to change the function of a control module ???
