I just bought a new 2015 A3 2.0 quarto after owning an A6 for 8 years. I have 700 miles on it, and have needed 3 calls to Audi roadside assist, 1 for a tow and 2 for flat tires.
The 1st call was at, no joke, 300 miles. The fuel pump went bad. It had to be ordered, and so I was without my car for 3 days. I had a loaner, and of course it was free. I have been told that the 2 bad tires have occurred because I hit potholes, and yes, it's been a bad winter, but I never blew a tire on my A6. Spending $600 on tires in 4 days has made me very cranky.
I'm worried about this car. Wish I could recommend it but at this point I can't.
