Yes, it was me
I only replaced the front ones, but when I ordered new ones from Audi, I was given a choice of wood ones to match the rest of the interior.
I figured they would last longer than the standard rubber coated ones, so went with them. Unfortunately, the match to the rest of my wood trim isn't too clever. I still prefer them to the rubber ones though.
Have a look at the thread here...
