I'm almost embarassed to post this, it seems so insignificant. I hit a pothole with my 2008 M3 and the "Scan ^" button popped right off of the dash and I could not locate it. I am about to sell/trade the car and I don't want to list it with a missing piece like this. Can anyone direct me to where I might find such a thing? Or, if you happen to have one in your parts arsenal, I will gladly pay a premium for it. I just need the cap, not actually going to connect it. I have never posted on a forum before, I apologize in advance for any transgressions.
