Mirror caps just pull off, fold the mirror into the 'safe' position then just tug focusing your effort on the smaller end.
Rear S
badge comes out like:
1) Removing the inside boot trim (5 torx if I recall. 1 in the handle, 2 under the lock flap and one behind each light cover) Then tug the f***er really hard. The plastic trim clips (metal tangs) are tough little blighters.
2) Unbolt the mechanism cradle which is 3 bolts.
3) Unbolt the S-flip unit from the cradle, another 3 bolts.
4) Hopefully you can see the end of a metal shaft now in the end of the plastic curve that contains the S. The S pivots around this. Punch it out as gently as you can et voila!
Just take your time and do
NOT be afraid to tug hard on the inside boot trim!
When you refit that shaft, grease it up well on the smooth surface as a lack of this is what causes a sticky boot release.
When you refit the plastic trim just make sure all the metal tangs are in place correctly i.e. In the actual boot and not in the plastic.
Good luck!
