The display for the onboard computer in my Mercedes C180 has turned itself to a bright white which makes it impossible to read the settings. It happened after having the car parked at the airport for 10 days. Is there a way to adjust it back to normal myself or is this a job for the garage? Many thanks!

Hi Ive got the same thing white screen I think it may be damp as I transfered some koi carp last weekend and some of the water has splashed around... Im hoping with the sunny weather it may put its self right. After reading you left the car for 10 days in a car park Im guessing it can only be damp....I see you posted this in March has it righted itself yet? Regards

Depends on the age of the car model type.
On the early version The mileage trip reset button was also a rheostat for dash lights you twist the button clockwise or anti clockwise to adjust dash lights.
