So I am not even sure if I am in the correct forum, but on my S85, I get an audible chirp through the sound system the first time the car passes 25 mph from a sleep. It is very subtle, but once I noticed it, I can't get it out of my mind now. Anyone else have this, and does anyone have insight as to what this is? If it is common knowledge, I apologize, but I could not find anything with a search. I appreciate your thoughts!
