I went and saw the same problem with my light switch... it's barely there in the left lower corner but it's starting. Some white fuzz, whatever that is.

BTW, I recommend doing as much fixes in 1 shot at the dealer when possible. Each time I bring it in they manage to do something to my car. Last time they dinged my front right rim. Time before that another dealer scratched my fender (the big thread I had). At the body shop they scratched the back too. Nobody cares about your car but yourself.
