This is my first experience wiuth Audi after owning Volvos, SAABs, and BMWs. I bought the car this past summer with 32K miles on the Audi CPO program. The brakes are touchy/grabby, but I've learned that's a common trait with the A6, and I've learned to live with it and adjust. At 36K miles, the engine quit in traffic, and I had to have it towed to the dealer for repair. It turned out to be a faulty low fuel pressure sensor, and this was repaired under warranty. The following week, a simple daylight running light bulb went out, and this an only be repaired at the dealer!
The car is a beautiful style and handsome even 4 years after its birth. Interior is top notch and I even prefer it to the 2012 loaner A6 I am driving this week.
Fuel economy is outstanding and the car just glides at 90mph.
However, the CVT transmission is quirky and I would opt for the Quattro next time around.
Car is sluggish off the mark and much of that is around the CVT. I had it in twice this year for rough idle and jerky driving when cold. Also, Audi refuses to update their software in a timely manner for the Media Center and is behind the curve of technology despite what the commercials tell you. Remote doesn't roll down windows and no streaming music from your phone to Bluetooth.
Amazing car to drive in the winter. The car looks great and is subtle but still turns heads. Great sound system and love the rear heated seats. But, the reliability on this car is horrible. I've never been to a dealership this many times. The check engine light has come on today for the 7th time in the last two years. I don't care what the excuse is, a new 50k car should not have these kind of problems this early on with this few miles. I'm getting annoyed with this car, despite it's capabilities during the winter. I wish Honda could just buy out their quattro awd system. It'd be the perfect marriage.
I sold my M3 because my kids were getting too big for the back seat and my wife couldn't drive a stick. I owned a 2004 Allroad at one point and loved it so I thought it'd be cool to come back to Audi. Well, now it's three weeks later and I just sold it for a BMW 535. The seats, while nice, offer very little support when going through hard turns. The headroom is terrible - I'm 6' 3" and my hair brushed the headliner every time. The car is very smooth - almost too smooth. I felt like I was driving a luxury yacht. Performance of the V8 is pretty good and with good mileage. If you like to float in luxury, this is your car, but if you're looking for a little better driving experience, pass.
Update to my earlier review. Now I have over 105k miles on this car that I purchased new. It goes through brakes but it has otherwise been faultless. Still love driving it. Same great ride, no rattles and no issues. Recently had to add some coolant, but other than that, just routine oil changes.
