The 2 different Curt trailer hitches fit 2 different models of the 2016 Audi A5. For a model that has the dual muffler design I recommend trailer hitch # C11188. And for models with the single muffler design I recommend trailer hitch # C11037.
Curt also says you have to use stabilization strap # 18050 when using this hitch for any non-trailer load (such as a bike rack or cargo carrier) per their warranty requirements. view full answer...
