The fact that the centre dashboard screen does not do the same thing leads me to beleive that it's not the fuse but the speedo panel at fault. That's why I asked the question - pls be patient my friend..
I am afraid this is going to be a rather involved job if your thinking about a replacement.
However somebody here ( sport tourer I think ) mentioned that he was thinking of offering a repair service for the speedo panel.
I'll have a search through the forums and see what info I can dig up on the subject..
