I am now driving my third Golf Estate, a 14 reg which I have had from new, but this is the first one in which the doors freeze shut in the winter. It doesn't have to be very cold, -1 will do it, but I really would like to have an idea how I can prevent it happening before the winter arrives. I have, so far, managed to open one door so I at least have been able to crawl in and start the engine to warm things up, but I'm really scared that one day I won't be able to get in at all!
