I had a cel and was talking to a vw salesman at the dealership in Florida and he showed me a new Passat and said I could get the trim through VW. Basically its on the lower front and rear and replaces the black molding on the very bottom with your car color. Fills bumpers nicely and looks really great. Nothing ground effects looking but really cleans the look of 2012-2014. Has the exhaust opening too. I should have snapped a photo. Has nothing to do with rub strips or molding. Probably standard on all the 2015+. As you can see here
