Just set mine up as per the Manual and I can confirm that the mirrors pair with the key, although I have had issues with my Cupra ID which now seem to be sorted? The nearside mirror can be programmed to drop to the kerb when selecting reverse if you follow the manual BUT, please note it only works with the mirror selector switch set to 'R' (Iguess this is a carry over from LHD cars?), which means you either have to select it each time prior to selecting reverse, or leave it in 'R' and not benefit from the mirrors heating with the rear screen heater - bit of a nonsense really and hopefully something Cupra will look to sort in the future!
