Yes VW, I hope you are listening, that is a mad piece of logic built into your security that allows this to happen!! Fix it, please.
This is what happened to me:
Wild camping in a forest near Arrochar, Scotland. Keys in the ignition, ignition off. I go to sleep, but before I do I lock all the doors using the switch on the drivers door. In the morning I jump out of bed and get some breakfast then think about getting ready for some hill-walking, so need my boots from the back. I leave via the side-door, closing it behind me to keep out the midgies. The tail-gate won't open and shock horror, neither will the side-door. This can not have just happened to me! I quickly check the other doors in complete disbelief. Surely the bloody thing can't have been that stupid! I stare at the keys in the ignition, I stare at my i-phone on the dash. I then think, my god, what am I wearing. There was one other camper about 50m away and that was it. If it hadn't been for them, the answer could so easily have been, nothing!!!! The other van was all curtains drawn, it was 0630. I was wearing jeans, sandals, T-shirt and thankfully I had my wallet. I hitch-hiked into the village some 5 miles away (imagine doing that in your pants, or less) and used the public phone to get my wife to find the number and call out the recovery service. Now here is the lucky bit. An Arrochar RAC man, calls in on duty and gets given my job and is told I am hitching back to the van. So it is him who picks me up!!! Two plastic wedges, two inflatable bags and a long flat piece of mild steel later we are in. Whole gastly episode lasted just 60 mins, and I was in the middle of nowhere. Not bad outcome in the end.
I am now completely paranoid and wont leave the van without the keys. I have tried without success to repeat this at home. So i am baffled!! Watch out!!!!
