Before we bought our cali (Charlie) we hired one, this was back in 2010. I recall we were at a campsite near Winchester, our two labs were in the van and we were just returning to the site. As we pulled up there were lots of people gathering around to see some Morris dancers, we hopped out leaving the dogs inside for two minutes, I locked the van but the missus went back for the camera opening the passenger door. happily armed with camera she was walking towards me when we heard the clunk of the locks and the indicators flash, at which point, without a word we both knew she had left the keys inside. So, the van is double parked, the dogs are inside, I had no phone no wallet no nothing, the Morris dancers are prancing away and the alarm is about to go off. S**t, s**t and double s**t, what was I to do! I had to phone my sister (reverse charge) get her to look on the internet for contact details of the hire company get her to phone them to get them to phone me to arrange them to come to the site and save my bacon, it was an awful 10 minutes! fortunately, the hire company came out and were with us within half an hour and the alarm never went off, phew.
You can turn off auto locking in VCDS, Mine is!
