Hi..
Just recently my 89 535i (E34) has had an intermittent problem where all gauges including speedo,tacho,fuel,temp,check display and odometer turn off. It's as if the ignition has been turned off. I can still drive the car but have no idea of speed, engine temp, etc. If I wait a while and restart the car it comes back to normal. The computer with outside temp,time, consumption, etc still works. I've also noticed that if i leave handbrake on or outside temp gets below 3 degrees celcius I don't get the warning "gong". Can anyone shed some light on this problem?
Many thanks in advance.
