i wanna use one of these to control my remote garage door opener.

There's already a thead about this somewhere - excellent piece of detail!

You may be able to get the P off with a solvent and some gentle rubbing. I say may because it could damage the plastic just as easily.

On mine (originally an "ASR-off" switch) the script is moulded in, not just a transfer so solvent isn't going to come off with solvent

I was going to install a USB socket in one of my blanks but I can't see how to get the blank out? I can get a finger in behind and push but it only comes half way out.

You need to do some dismatling of the dash to be able to get the blank out in my experience, not hard to do - sorry can't remember exactly what i did!

Remove the fascia / trim surrounding the head unit (open ash tray and pull from the bottom of the trim and work upwards). Then each of the buttons / blanks will pull out.

If anyone wants a spare blank to practice on, I think I have one, maybe two, in the garage going spare... PM me.

Thanks all. Any thoughts on how that particular switch works. I think its toggle on off??

It doesn't have a physical on & off state (like on a torch for example). It's just push to activate/deactivate and then it returns to normal 'out' position.

Like the ASR/ESP button, except that only has two illumination states, the PDC has three as already mentioned.

When you say push to activate / deactivate what is the difference between de-activate in that context and the 'normal out position'?

It's sprung loaded.

Any push is met with resistance of tve spring and the button physically moves back to the 'resting' state.

Push to activate. Push again to deactivate. Apart from the illumination colour, you wouldn't know the difference by looking at the button.

Thanks kb, I understand that is how it works but sorry if this sounds thick, but to me that's still only two states, activated and de-activated. Isn't it?

Electronically, yes. But there is no physical difference between the two.

Think doorbell as opposed to light switch....

Hmmm but you don't have to hold the switch for the front sensors to operate, as you do with the esp or tpms equivalent. Granted it turns off as speed is increased but that presumably depends on other wiring not the interruption to live. I realise I would need the illumination to tell which state the switch is in.
