Hello D4 owners,, I'm thinking of using D4 armrests in a retrofit project. Can someone provide the length, width, and height of the armrests?

Also I've seen 2 different type of armrest, one with a button on the side like in the image and one without the button. Anyone know what the button does?

Thanks in advance for your help!

May be a position (height) adjustment button.
I can tell you that my 2012 doesn't have one of them, and the adjuster button is a little awkwardly placed, so may be connected to newer model years...

Not in 2015 U.S. A8s.

2011 doesn't have that button either, the height adjustment is on the button under the nose.
