Cupra 280: After holiday problems with exterior mirror

Hello forum, my Cupra 280 DSG stood around for three weeks (holidays). Now I have the problem that I can no longer fold the outside mirror with the key remote control and open the windows no more. However, it goes up and close. In BC I have mirror flaps active. I also noticed that the red LED of the alarm system in the door lights permanently. I mean to remember that the otherwise flashes (but I can also remember wrongly). Does someone have an idea what Is that where it could be going?
