We've updated our reliability stats for the A6 / S6 to include owner experiences through September 30, 2014.

Repair frequencies, in terms of repair trips per 100 cars per year:

2004 A6: 72, moderate, very small sample size
2003 A6 / S6 / RS6: 110, moderate, small sample size
2002 A6 / S6: 126, high, small sample size

2000 A6: 148, high, small sample size

We have two additional statistics, "Nada-odds" and "Lemon-odds", to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop:

2006 A6: 46, 4

Additional participants always helpful (especially if you see "small sample size" next to the year, or no stat at all).

So, how have these cars been doing lately?

Our reliability stats for the A6 / S6 now include owner experiences through March 31, 2015. (Others are nearly a year behind.)

In terms of repair trips per 100 cars per year ("low" is best):

2004 A6: 46, low, very small sample size
2003 A6 / S6 / RS6: 119, high, small sample size
2002 A6 / S6: 74, low, small sample size
2001 A6: 128, high, small sample size
2000 A6: 121, high, very small sample size

Additional participants very much needed for this generation--all of the sample sizes were small. Next updates in August and November.

Our reliability stats for the A6 / S6 now cover the year ending June 30, 2015. (Others are over a year behind, and so report how these cars were doing when a year younger.)

Repair trips per 100 cars:

2004 A6: 38, low, very small sample size
2003 A6 / S6 / RS6: 105, moderate, very small sample size
2002 A6 / S6: 66, low, small sample size
2001 A6: 134, high, small sample size
2000 A6: 97, moderate, very small sample size

As suggested by the notes, additional participants would be very helpful.

We've updated our reliability stats for the A6 / S6 to include owner experiences through the end of 2015, about eight months ahead of other sources. In terms of repair trips per 100 cars per year--lower is better:

2004 A6: 68, low, small sample size
2003 A6 / S6 / RS6: 123, high, very small sample size
2002 A6 / S6: 68, low, small sample size
2001 A6: 134, high, very small sample size

The differences by model year could be a result of the small sample sizes. With more participants we could provide more precise stats for the C5.

We've updated our reliability stats for the A6 / S6 to include owner experiences through June 30, 2016. Reliability information elsewhere is based on a survey conducted in April 2015--well over a year ago.

Repair frequencies, in terms of repair trips per 100 cars per year (lower is better):

2004 A6: 97, moderate, very small sample size
2003 A6 / S6 / RS6: 130, high, very small sample size
2002 A6 / S6: 118, moderate, very small sample size
2001 A6: 149, high, very small sample size

As suggested by the sample size notes, additional participants would be very helpful for this generation of the A6. (The survey currently includes from 2002 on.)
