Parts 16 and 17 listed as clip lower and upper. From the diagram, it would appear that 16 is included with the door card presumably it's under the speaker grill so not really accessible. But will 17 be on the door panel once the door card has been removed?
Their part numbers are:
6Q0 868 297 – clip lower part x1
6Q0 868 246 A – clip upper par x1

Looking on the thread Shaun started about replacing the door warning lights, there's nothing obvious as to what this 16 and 17 could be:

Any ideas if these parts are something I would need to worry about?
