I have a late 2015 1.6 dtec and have had it a week so far, and all good. Today I decided to reset the door opening function from drivers door only to all doors open. After a lot of button pressing (very complicated to me) managed to set to open all the doors. BUT, there is now a constant CTBA warning coming up, and I can't open or close windows, start the engine, turn on the radio. Probable other things too.... Where have I gone wrong? All the warning lights come up.
