This Video should help you to fix your broken Sunshade on your Tiguan or Audi Q5 they pretty much the same. I did probably more than 10 of them they not easy to do but the way I do it should save you some good money and time. Most people show only how they take it apart and than it stops or do not shop the finish product actual working or removing the whole headliner well think about why :)
Just watch the video ask questions before hand please subscribe and I will get back to answer as much I can. Good Luck !!!
