I have mine done at the Porsche/Audi dealer that I work with. You might try something similar, these guys really like the car and that goes a long way
The tech that works on my Audi does it for about $40 bucks and a ride/drive. The shop dosen't make enough to cover expenses but the tech works late to do it. I've never had it done anywhere else, no reason too.
I'm in MI, no idea about service in the bay area.
