Audi Spindles?

I got my front spindles and hubs back from Lanner today, and they look beautiful. I ended up just purchasing new stock spindles from him, and when I was oogling them I noticed the spindles have both the VW logo on the back, and they have the Audi logo. I assume everyone else has noticed this also, but did Audi ever use balljoint front spindles? I was looking at someone elses picture of their corner assembly (also machined by Lanner), and they didn't have the Audi logo. Anyone have thoughts or an explanation?
