Congrats...enjoy..I recently picked up a 2015 too....6500 miles Certified Pre-Owned. For US Q3s, the mirrors only manually fold..not power folding, which I think is an option in Europe.
Found an amazing deal on a black 2015 Q3 and I'm already head over heels. It's so adorable and sharp and the perfect little SUV for city driving. So glad I found this forum though as I haven't bought a car in 10 YEARS and all the fancy tech is really a learning curve for me. Still trying to figure out how to fold in the mirrors! Looking forward to getting to know this car and this forum!
