The only time I disconnect is when parking at a Caravan Park.. Leave it attached. You are only creating unnecessary work for your self.Hi everyone I was wondering if we should unhook our van each night as we travel North to spare/relieve the airbags in our Touareg. Thinking we probably should, but wondering what others think. Our last tow vehicle was a Pajero and this is our first trip away with the Touareg. Would love some answers on what others do or don't do. Thanks.
