I don't mind looking up specs for folks when I have time but anyone who's going to wrench on one of these cars needs to purchase the PDF's from Audi. They're less than $40 and you own them for life (or til your computer hard drive crashes and you loose everything!). It's really easy.
Go to To get the factory service manuals for your vehicle go here:
https://erwin.audi.com/erwin/showOrderFlatrate.do
You'll want the 24-hour flat rate which is under $40 (euros, so it fluctuates).
You'll sign up for an account (free). Choose the flat rate one day. You'll then be able to search for any and all PDF's related to the RS5, S5 and A5 line (or any Audi for that matter). Some of the PDF's don't specifically say RS5 or S5 and will say A5 repair for whatever but include RS5 and S5 information. So I downloaded pretty much everything I could for the A5/S5 and RS5 and sorted through it later. Just search a number of different ways. Plus you can download lots of other cool docs on other models.
Once you've downloaded, you can open them on your computer at any time. If using Adobe Acrobat, disable Java and you'll get rid of the initial warning PDF that pops up. You just scroll to the bottom of those and hit "Ok" and the FSM opens. But just disable Java in the preferences and you don't need to do that each and every time.
