I have a 2018 A6 Avant S-Line (C8) and one of the lower front bumper inserts is cracked. Does anyone know how to remove it without having to remove the bumper? Hoping to just order a replacement online and fit it myself but don't really want to have to take off the bumper etc. I've tried pulling it but can't see where the clips are. If anyone had a diagram that would be very helpful.
