Started the car this morning (quite frosty) Q5 S-line 2015 switched on rear screen heater as well as the front screen defrost system after about 5 mins I moved the the car 10 meters or so prior to setting up to valet the car after the Christmas break. Parked the car but left the engine running whilst I moved another vehicle and whilst walking around the car I heard a cracking, popping type noise and on inspection the rear screen had blown out.
Audi Poole don't really want to know when I spoke to them, although a service advisor did a company search for any history of this kind of incident and reported back with nothing they could do, no diagnosis, nothing!
Quite alarming really!
Not really sure how to move on from this situation.
