I have mitigated it slightly by always removing my key from my pocket when I get in the house just in case, I turned off all but drivers window and that did make a difference but the doors opening isn’t just confined to this car as I have known it happen on other sliding door cars.
I can’t have global opening turned off completely as this is the system that the remote folding/unfolding of the wing mirrors on the keyfob is linked through.
Not sure about it’s own thread as I doubt VAG will do anything about it as it took them 4 years with the golf that used to wind it’s windows down if it rained heavily and was eventually attributed to a faulty drivers door locking mechanism(you had to pay for modified replacement and fitting yourself)
