The Auto re-lock is a feature on all VAG cars/vans.Well, no auto lock on my camper. When I drive off the doors will lock and when I take the key out the doors open (at least that works), but cannot find/get auto lock to work. Need to look more into this, perhaps my van does not have it.
its a security feature, so when you sit on your keys in your pocket at home and unlock the van from your living room . . . . without realising.
the van will wait 30sec or so, then if NO DOOR is opened it will RE-LOCK the whole van.
BUT . . . .
if you do open ANY DOOR, it assumes the key press is legitimate and cancels the RE-LOCK feature as it assumes you are in or around the van, and stops this exact problem. (getting locked or having keys locked in the vans interior)
ie . . . in my old non vw van.
blipped the van open,
threw keys on front seat,
got tools out tailgate,
closed doors forgetting about keys,
5mins later van locked all doors with keys inside !!!! Grrr.
