I've just fitted a RS Reflector Bar to my L&K, which I think improves the rear end appearance.
There are 3 parts involved, total cost from my local dealer inc vat - £91.63:
Protective bar - 565807423A9B9 - £58.34 ex VAT
Reflector - 565945103 - £9.01 ex VAT
Reflector - 565945104 - £9.01 ex VAT
Fitting does not require the rear bumper to be removed. There is some minor modification involved in the fitting as the reflector studs protrude through the rear of the bar, that is not beyond the means of an average d-i-yer with a 13mm drill and a dremel taking around 1/2 hour, simply because the RS bumper is not quite the same as other Kodiaq rear bumpers.
(Yes, it's due a first wash!)
