B8 S4 reliability -- let's get better stats
I wanted more up-to-date car reliability information that included actual repair rates. So in late 2005 I started getting people together to make this possible. TrueDelta now updates actual repair frequencies, not just dots, four times a year, to track cars closely as they age.
We've had excellent participation by Audi owners, with over 2,000 signed up, including over 200 for the B8 A4 and A5. I'd like to provide separate stats for the B8 S4--just a matter of getting enough owners involved. So I'm grateful to JET and this forum for providing permission to post about the survey here.
Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, at the end of each quarter.
To encourage participation, participants receive full access to all results, not just those for the Passat, for free. I'll share results in this thread after each update.
For the details, and to sign up to help out:

I've participated for the past few years and feel it's a tremendous service.
The 2010 A4/S4 is showing attractive reliability rankings so far...check it out.

Updated stats were posted for the 2010 A4 last month--it's better than average so far. Not enough of the new S4 to split them out this time around, but there will be a further update in August.

We've updated the results for the B8 A4 and S4 to include owner experiences through June 30, 2010.
Other sources of car reliability information won't cover the more recent months until the summer or even fall of next year.
Repair frequencies, in terms of repair trips per 100 cars per year:
2010 A4: 36, better than average
2010 S4: 27, better than average, lower average odometer (3900 vs. 5900)
2009 A4: 72, about average
We'll have further updates in November and February. The more owners participate, the better the information we can provide to everyone.

Starting this month we have a new question to measure, as objectively as possible, the severity of a problem. Many people have been asking for reliability stats that weight problems by how severe they are, and once we have enough responses with the revised survey we'll start providing this.
Also this month: updated reliability stats.
As always, the more owners participate, the better the information we can provide to everyone.

We've updated the results for the B8 A4 and S4 to include owner experiences through December 31, 2010. Other sources of car reliability information won't cover the months since April until the summer or even fall of this year.
Repair frequencies, in terms of repair trips per 100 cars per year:
2011 A4: 18, better than average, small sample size
2011 S4: 80, about average, very small sample size
2010 A4: 33, better than average
2010 S4: 73, about average
2009 A4: 75, about average
Repair frequencies for the S4 are being heavily affected by very common water pump failures.
We'll have further updates in May and August. The more owners participate, the better the information we can provide to everyone.

re: Repair frequencies for the S4 are being heavily affected by very common water pump failures
Thanks for clarifying that. That's just the 2011, or the 2010 as well?
Is there a way to get an adjusted number, subtracting the water pump issue out?

Sorry, I should have been clearer. The water pump issue affects the 2010, not the 2011.
I don't have an easy way to remove it. But looking at the repair reports that are posted to the site it looks half of the reported repairs might be for the water pump.
