When we were first shown our new S5 it was still wearing all of the factory shipping protection ( plastic seat covers etc ).
The colour coded lock protection cover, was missing from the drivers door.
When I pointed this out to the sales agent, he said that the cover will be in the glovebox, as they all come without the cover already fitted for shipping purposes.
It will be fitted when we do the PDI / final clean and polish, prior to delivery, which it was.
I think they leave the cover off, just in case the 12 battery runs low and they then can use the emergency blade to gain entry into the car.
If it had to be removed in transit, it would very likely be lost somewhere on route.
Replacing the missing cover is easy enough, but I would guess that the replacement is not colour coded, so a real faff having to paint a tiny cover every time one is lost.
I know the replacement external door handles are not colour coded as standard on the ZS EV, they are only supplied in primer finish.
Like many of the plastic parts, bumper covers / petrol / charging flaps etc ( if coloured ).
