Updated reliability stats next month.

As always, the more owners participate, the better the information we can provide to everyone.

Car reliability research

 

We've updated the results for the B7 A4 and S4 to include owner experiences through September 30, 2010.

Other sources of car reliability information won't cover the months since April until the summer or even fall of next year.

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

2008 A4: 62

2007 A4: 61

2007 S4: 102, very small sample size

2005.5-
2006 A4: 80

2005.5-
2006 S4: 66, small sample size

All results for the A4 are about average, and remain considerably better than the B6.

All are about average except the 2007 S4, which could be inaccurate--very small sample size for it.

We'll have further updates in February and May. The more owners participate, the better the information we can provide to everyone.
