Dave my car is 2014 plus 4 and been having the same problems ,on and off for ages, after I leather covered the cowl. So now I have done what you have now done and made the hole in the cowl and leather the same size as the ring,and moved the ring to the edge of the cowl ,and no problems since,so it should work.duncan ( parked next to you at Mogfest)
Oh yes I remember our chat!
