Sounds like a dry joint: circuit heats up slightly then breaks contact.
Could also try replacing the capacitors, there's details on bmwe34.net
this has happened twice now, i'm driving to work and the dash display is working fine then all of a sudden all the gauges and display go all at the same time, and all i get is the warning light in the bottom right hand corner of the dash, i get to work, leave the car for about an hour, switch the igintion on and everythings fine, at the moment it happens once a week, is there something else that controls the dash cluster that i can check?
Thanks in advance guys
Rob

Mine has been going out like that also, a smack to the top of the dash makes everything work again, it acts like the key is just put into ignition 2 position, fasten belts, then all the dings afterwords I haven't had time to mess with it any lately.Originally Posted by nizmainiac

if in doubt get the hammer out eh? i give that one a try the next time it happensOriginally Posted by Phatty5BMW
Interestingly I have the same problem. Mine was preceded by false Trans program issues. I actually have a new (yes 800$) cluster board and the problem is still present. My belief is that there is a loose or broken or corroded wire under the dash (power or ground). I hope to fix when after I get my summer car ready to go.
