I?m in the U.S. and just started looking into purchasing a Q5. A good friend of mine who did some research but ultimately decided on a Lexus RX pointed out that Audi won?t install Running Boards or a Trailer Hitch if a Panoramic Sunroof is in place. The Running Boards I can do without, but I can?t do without the trailer hitch nor a sunroof. Can anyone confirm this? If so, is this because the Q5 can't handle the additional structural stress if the sunroof is in place? The Audi Accessories brochure I found within this forum makes no mention of this. My fear is if I go ahead with my plan on my own, I?ll be stuck with a leaky sunroof that Audi won?t cover under the warranty. The Audi Accessories brochure I found within this forum makes no mention of this.
