we have done several Audi headliner repairs for both the A5 & S5
All of the 2010-2017 cars had bonded listings holding the fabric up,which has a very high failure rate.We remove the top,remove the H/L,tape list in proper location & sew it together. You only see a single stitch line inside the car,if you find an 2018 or newer car,they have a seam. with this repair,it will stay for years.
We are in Indiana,and our fee is $1250.00
