Hello people new to audi and owners club. I am missing a few things.. The first is a plastic cover that covers a hole next to the fog light...one side has an air defuser which directs air at the inter cooler which is still there the other side is ment to have a blank thing...does anyone know it's name and how I could get one. Another thing missing is the near side front wheel arche mudflap, the mudflap that the undertray connects too just behind the front bumper....it may not be called a mudflap lol
