Turn signal switch malfunction. When turning right turn direction on, the left turn goes on instead of the right turn. After researching the issue, it looks like it’s a common issue with Audi. This is a safety issue and need to be recalled asap.

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.

The engine had catastrophic damage. I was driving, full oil, and the engine just died. The mechanic said the engine was destroyed and believes it was a manufacturing mistake.
