Rattle cured thanks to Internet

How the Internet has changed our lives. My old BMW X5 has had an annoying rattle from the rear for about the last two years. Finally it got too irritating so I investigated - seats, spare wheel, floor covering. loose items .... nothing I could find to cure it. My wife said 'Google it' and the solution was staring me in the face - adjust the tailgate rubber stoppers with a Torx driver.  Time to fix - 1 minute on Google, 1 minute with a screwdriver, oh, plus two years fiddling around!
