I think (not had much of chance to test it thoroughly) that the autoglym rubber and vinyl care has improved it - cant say for sure if it has eradicated it. Will report back. As I mentioned earlier a load of people are reporting that its to do with the rubber seals either round the door or round the window itself. I don't really understand the logic, but who am I to argue if people are fixing this by greasing up their rubbery bits
