Audi A6 for Sale

Edmunds' Expert Review

by the Edmunds Experts

Pros

Heavenly cabin furnishings, crisp handling, all-wheel-drive utility, strong six- and eight-cylinder power plants.

Cons

Steering not as sharp as a BMW's, no manual transmission available.

What’s new

The A6 gets a top-to-bottom redesign for 2005.

Edmunds says

Solid performance and an elegant cabin design make the A6 a worthy competitor in the luxury sedan class, but BMW's 5 Series is more athletic and Mercedes carries more brand cachet, so it can't be called a class leader just yet.

Joy to drive, pain to spend needlessly for repairs

Sean, 01/24/2016

2005 Audi A6 3.2 quattro AWD 4dr Sedan (3.1L 6cyl 6A)

We have had our 2005 Audi A6 3.2 for about two years and bought it with about 106,000 miles. This car is a great looking car and very fun to drive, but none of that matters when reliability is an issue. I can honestly say that unless I win the next mega lottery I am never buying another Audi. Now before you dismiss me as a hater I want you to know I really wanted to love this car. I … like German engineered cars. I had a few BMWs before and liked those, and my wife had a 2000 Audi S4 for a couple years that was also a fun car, but had maintenance issues that should have warned us from buying another Audi. We had an extended aftermarket warranty on that car though, so I guess that helped us "forget" about the issues. Right from the get go the A6 was trouble. When accelerating from stop signs there was a drastic delay before the car would shift into gear and start moving - you would push the accelerator and nothing would happen for a couple beats and then it would suddenly take off. I finally learned that if I kept the car in sport mode that didn't happen. Sport mode is fun so I didn't mind too much, but my MPG suffered. After returning the car to the dealer I bought it from a couple time they still couldn't fix the problem and offered to put a new transmission in for $1,200. After agreeing to that I soon discovered that did nothing to fixed the problem! That set the tone for a trend that continued throughout ownership. Every four months or so an issue would pop up that required a trip to the local Audi dealer for repairs. I started to joke with people that a trip to the dealer was always followed with at least $500 in repairs. The icing of the cake though occurred last week when we brought the car in for a failed battery. At this point we have 123,000 miles on the odometer and we asked them to change the oil as well. Then we got a phone call from the dealer saying that the timing chain was stretched and the car sounded terrible. They would recommend we don't drive it but have it towed if we want a second opinion. The repair would cost $5,000!! And that was just to repair one of four chains in the engine. To repair all four the cost would be $8,000. That was just the repair of the timing chains and there was no guarantee that more damage wasn't caused to the engine when the timing chain broke. Now after reading some forums and talking to some repair shops I have learned that this is fairly common with Audis of this time period. Apparently Audi went to the timing chain versus timing belt set up starting in 2005 and the new chain system trends towards failure on a good percentage of the cars between 110,000 and 150,000 miles. Now some people may say that is is a common result of neglected maintenance. I can tell you I was current on all of my oil changes and service. I can't say what the history of the car was before I bought it, but this drastic problem with a ridiculous repair price tag is unacceptable. If you look up the value of my car, this repair costs more that the car is worth at this point. So although I typically don't write reviews, I felt obligated to share my experience in hope that I can save some other car buyer from the same fate. The dealer was useless and offered no assistance with this major repair even though THEY broke the car while it was in their shop. This is one of the big Audi dealers in the Twin Cities. In the end I sold the car for $2,500 as is, even though I still owed $7,500 on the loan so I got to pay off the remaining $5k for nothing. Do yourself a favor and buy BMW or Mercedes if you want a high end German brand, or go with Lexus.

2005 Audi A6 3.2 quattro AWD 4dr Sedan (3.1L 6cyl 6A)

Audi A6 drives beautifully when it works, but is very unreliable. Have had my A6 serviced for same problem of all of a sudden shutting down and not accelerating properly 5 times in last 3 months. EPS computer fault system continues to fail. At times won't change gears properly. Buyer beware, and Audi no longer offers free service. Audi so far is refusing to replace the vehicle …

2005 Audi A6 3.2 quattro AWD 4dr Sedan (3.1L 6cyl 6A)

I have owned my A6 for 5.5 years and still enjoy it every time I get behind the wheel. Handles great and fun to drive. The overall quality of the car is very nice. My biggest complaint is the low profile tires. I have spent close to $5,000 on tires since I owned the car. They are good for about 25k miles and the pinch easily. I will admit Most of the issues were caused by me …

2005 Audi A6 3.2 quattro AWD 4dr Sedan (3.1L 6cyl 6A)

I have owned my 2005 Audi A6 Quattro for almost a year now and have have problem after problem. From a rear-end differential to a 2,000 dollar steering module just to start the car even though there were no problems mechanically. I caution you if you’re thinking about buying a used Audi A6 to keep thinking and move on because this car will nickel and dime you until you can’t afford to …
