Thanks for posting these instructions.
I ordered the holder from my local BMW dealer in UK for £17.
Removing the gaiter was easy, and with a firm pull I removed the silver trim on the center console.
The lid, like many others, was resistant to removal. In the end I used a tool for removing the backs off snap fit watches, but really any strong blunt knife like a butter knife would do. I had to use so much force that I thought I was close to breaking something, but in the end all 5 clips released and the lid cam off.
PS What a complex over engineered ash tray. This should have just been a pop out the ash tray and lighter and snap in the sunglasses tray solution.
Anyway, good job done in the end.
