Just painted mine..renault pearl black... and my "clio" badge at the back..which was red...
How do you get the rear diamond off??
For the rear you have to pop the plastic off on the inside of the boot, it has one torx screw and the rest just pops off, about 7 clips i think.
Then you have to unscrew the 3 bolts holding the boot lock on, then slide the boot lock off the bolts, then pull the plastic cover (that the badge is set in) off the boot, it'll be quite a tight fit as the screw threads almost grip the holes, but a good yank will do it.
Then theres lots of little clips holding the badge on, but i snapped them all off as they really do f**k all. Whats really holding it is double sided tape (with almost 100% contact).
So ALOT of pressure slowly but evenly on the back of the badge will pop it out!
Putting it back on, it some how clipped itself back on, although like i said, i snapped most of the clips off. :S
