MMI system worked during test drive and then NOT worked after final sale: Safety systems included: The Multi Media Interface (MMI) system is an in-car user interface media system developed by Audi, and was launched at the 2001 Frankfurt Motor Show.

The second (not movable) glass pane of the "panoramic sunroof" spontaneously shattered. That happened three days ago, because of the potential for water damage I need to have this repaired as soon as possible. However, until I get it repaired it is available for inspection. Apparently many Audi owners have experienced a similar phenomenon, commonly called "exploding sunroof", and other people have had the glass completely explode out. I did not have that happen but the glass did shatter entirely and completely. There was no rock or anything else that hit the sunroof as far as we know. It did leave significant cracks in the glass and I have photos of it. If the glass had completely blown out, it would have showered glass pieces into the passenger compartment. I did not involve the police or ask for a report. I will be taking the car to the Audi dealer and probably making an insurance claim because the repair will be fairly expensive. My car has always been dealer serviced on schedule. It is in excellent condition (outside of the shattered sunroof glass anyway). There were and are no warning lights or indicators related to the damaged glass.
