Anyway, I was really happy they took care of it because a new set of front pads and rotors would have been $$$.
I later learned that uneven pad deposit issues will occasionally go away after 6 weeks of light driving (when the pads are cold enough to scrape pad deposits off the rotors rather than add more), but I had only waited 4 weeks before taking it in, so it might have taken care of itself. But I still switched to different pads even though that meant giving up the Ultimate Service pad benefit because I knew the dealer wouldn't keep replacing pads and rotors for me, and I definitely didn't want to be buying new pads and rotors after every track weekend -- plus that wouldn't have solved the brake fade issue. First track weekend on the new pads and no vibration issues afterward.
Excellent read and response--thank you. I will print this out and show the SA when I get there on Tuesday morning. I am hoping this is just a simple "yeah we found the issue, no worries, we will replace them" kind of thing. My dealer (Richmond BMW) has been very good to me since I have had the car since January (gone in for routine maintenance, new battery, Updated DME, etc) and they have done everything for free (minus update) and did everything right. This helps tremendously. Will keep fingers crossed for Tuesday.
