This is a bit of a weird one, but I had problems with my clocks for ages (the usual thing of rev counter bouncing about and MFA going off completely) for about ooohhh 18 months.
Got the car out after a period of a few weeks off the road a month or so ago and hey presto, it seems to have fixed itself! Only thing is, the outside temp display doesn't work. I don't mean it displays incorrectly or shows '---' or anything, I mean when I'm clicking though the different displays it ignores that one and goes straight from oil temp to clock (or whatever the sequence is).
So I was wondering, could it be possible that a fault with the outside temp sensor or wiring could have been causing the problems all along (I checked all the other things like fuses, earth etc but could never find the problem) and now that's died completely eveything else now works? During the brief periods the MFA did work, the outside temp was there. I'm a complete retard when it comes to electronics I'm afraid

Anyway it's not really important it's just puzzling that they have been working now for weeks after so long of being broken
