Trip computer and everything else resets to 0 after a cold night.

Hi all...ive noticed wenever we have a cold night the little screen between the speedo and rev counter resets itself back to zero..the mileage and numbers till next service are ok it just everything else..like the trip mileage,miles left till fill up,avg mph,miles per gallon..but the car starts fine and they all start working fine again..but then in the morning they will all be at 0 again if its been cold overnight...but if its been an average night they all stay at were they were when i parked up...



im no electrician so dont really know were to start...thanks for reading
