Hi everyone, I need some advice. The middle doors on my T6 keep having issues. Sometimes they automatically open or close halfway and then suddenly bounce back. Other times the button doesn't work at all, and the door button flashes a fault. Sometimes I have to press the button twice, holding it down on the second press until the door fully opens or closes before I can release it. What could be the problem, and how should I fix it? Please help.
