My wife bumped a concrete wheel stop with the RS6, and cracked the right lower valance just below the lower right grill intake (brake cooling duct intake grill, I think). The grill fell out of the hole on the way home and I need to find a replacement.

First: what is the best way to fix the crack? ABS glue, fiber glass, something else, with a sand and respray of the valance?

Second: I did a quick search for a replacement grill, and struck out. Other than the dealer, anyone know where I can get one? Does anyone have a spare they want to sell?

Thanks for your help.
