You can check local retailers or online for aftermarket options. Brands like CURT and Draw-Tite may have 2" hitch receivers that fit the 2016 e-Golf, but hey, just confirm compatibility before buying.
I put a 1-1/4 hitch on my 2019, and it looks as if there is a 2” for that year. However, when I look on etrailer.com, it doesn’t show any hitches available for the 2016…
