Multi Function Lcd Display

[Kryten]

Hi again, have done search but can't find solution to my problem, which is, the Multi Function LCD Display has stopped working in that it has become stuck on the MPG setting and wont change with any button including the steering wheel, however what is concerning me most is that the display is permanantly ON even after removal of the key!!! Have pulled all the fuses relating to the display (37,42, and 50), but I cannot find 53 and 55 (in 52 to 65 block)?

Sorry I'm on a mobile and didn't see it and from northern Ireland where the plates are different.have you checked all fuse boxes?in engine bay and behind glove box?also I think there's 1 by the drivers side too?

OK, to save anyone else as much grief as I have had in trying to locate the fuse box, with numbers 52 to 65, it is NOT behind the R/H small trim panel with the fuse label on the back! In fact you don't even have to remove that panel to find it. It is to the left of the OBDII plug, directly above the accelorator pedal concealed behind a black plastic cover which reads "Fuses".

So I pulled the 15A blue fuse and at last the M.F. display goes off, but still no better off as on replacing it the display comes back on with the whole thing filled with random pixels and still permanently on even with key removed. Can't just leave the fuse out however, as that fuse also powers the sound system :(

Is the fuse ok try another in it.

Last update: Pulled the fuse again and left for a few hours, display now completely dead and also not on when key removed. So it looks like I need to replace the unit, except it looks like one needs to replace the whole thing which includes the surround with the air vents and hazards switch
