Hi all, New to the forum and recently bought an A7 3.0t 2011, loving the car. The two retaining pins that are in each arm of the tailgate that hold the tonneau cover in place (the larger section of the parcel shelf) have both been snapped off by a previous owner, the cover is also missing. I've got the pins from Audi but would like an idea of how to remove the tailgate arm trims, do they just unclip off? I need to get these off to remove what's left of the pins themselves. Any advice welcome Cheers
