Sbbamafan - just came across your post from 2019. Did you have any luck with a fix for your sagging headliner? I’m just up the road in Alpharetta and have the same issue. Must be the Georgia heat!! Let me know if you came up with a fix. ThanksMJ-Remote - I am right down the street from you in Roswell, GA and am having headliner sagging - a somewhat similar problem. I would PM you to get some direct advice but I dont have enough posts yet (need 15) to be able to PM. I am going to be trying to add some posts over the next day or so in order to get to this point. I look to get in touch with you soon. I have become very frustrated with our local Audi dealers.
