Hi have a quick question. Just bought my mk2 cupra and of course well pleased, but annoyingly when pressing open door on the fob, it doesnt open the rear doors. i have to press the open button about 6 or 7 times before the rear doors unlock. I have a rosstech cable so can I make these adjustments via vagcom? if so does it need to be done thorough coding or elsewhere? have looked at other threads but have only found ibizas, hence my question.
