"Audi Australia has called back examples of its A4 sedan, Avant and Allroad, as well as the A5 Sportback, manufactured between October 2014 and October 2017. The issue effects models equipped with Bang & Olufsen sound systems, and sees part of the aluminum trim strips on the front and rear doors become detached. Owner affected by any of the aforementioned safety recalls should contact their corresponding dealers to arrange a free-of-charge repair." This was in local media today, & do not recall the problem being discussed here. Any affected UK owners now have some ammunition when they approach their Dealer. Good luck!!
