'97 BMW E39 528i.
After a cold night on drive. Unlocked the car, put the key in to start car.
Instrument display dead. Nothing showing at all. Started car. No fuel, rev
or mileage reading.
Drove about 10 miles with nothing showing, Speedo, rev counter, temp, etc
etc all dead. Parked up and locked the car to get car park ticket. Came
back, unlocked car, and tried the key in the ign lock. Display lit up as
normal. Did a bit of shopping, and display was still OK when I came to drive
home, and remained so all the way home. I assume the problem has cured
Unusual, or not uncommon with BMW instrument panels?
