Hello, today I drove my 2017 4/4 out of the underground parking at a hotel. The driveway was so steep that the rear undertray was sitting up and it is now dented on the bottom left side. There is also a small crack in the longitudinal direction. Can anyone tell me what exactly is above the rear undertray and could be damaged by it? Thanks in advance.
Tom, that rear valance (tray) is made of some form of plastic. If you remove the spare wheel or cover you can see the inside. As you mention it's moulded to support rear fog and reversing light's. I doubt the internal damage will be any worse than external. Depending how bad It could be repaired with an internal layer or two of fibre glass cloth painted over black to match elsewhere. The exterior could be made good with filler then primed and painted with spray cans. It may be easier to remove from car for this work although it will require removal of overriders if you have them. The lamp internals are on bayonet fittings, so just a quarter turn anti-clockwise when viewed from back will allow lamp and wiring to be removed. The outer lens part stays in-situ fixed to valance with three screws.
