Hi Davilovigaro, as always megababat_1 is correct, temperature and humidity affect these pastellas in a very important way, if you already take the most caused thing it is not good to pass and if it does it will be in a much greater time, now if it happens again it turns on the air conditioning or opens all the windows and you will see how it is fixed, I have seen it in Peugeot and No LED that directly illuminates these screens are like clock or cell phone, the LED illuminate other intimates, but I emphasize that for example the Peugeot and especially the 206 when it is very hot and signage towards one of the sides the high lights are lit and with cold there is no problem, in addition the signs stick and when you step on the brake do not funeate, strange things of the electronics.
