We've updated the results for the B6 A4 to include owner experiences through March 31, 2010. In terms of repair trips per 100 cars per year:

2005 A4: 174 -- rush to get things done before warranty ends?

2005 S4: 167

2004 A4: 125

2004 S4: 141

2003 A4: 99, results for other model years suggest that this one is not accurate

2002 A4: 146

All but the 2003 A4 are worse than average. Results for the A4 and S4 are essentially the same. We've been seeing much lower repair frequencies for the B7 and B8.

Everyone who has been helping, thanks. We'll have further updates in August and November. The more owners participate, the better the information we can provide to everyone.

Sorry i have not caught up on this, but is the intended goal of this. I have a 2004 A4 that I've spent a lot of time repairing poorly designed and manufactured parts.

mkaresh

The intended goal? To provide everyone with a clearer idea of how many repairs different cars require. Would like to provide additional detail in the future, but to do this well requires more participants.
