Default Stock engine idle

What RPM do stock C5/A4s idle at?
It's been a while since mine was completely stock, (and my memory's not that good either)

In gear or out of gear?

On mine it's about 600 to 700 RPM (if memory serves me correctly)in gear and not to far off from that out of gear.

Thanks,Matt

Depends on the year. I know 1999 and 2000 idle at 725, and 2002 idle at 800. If I had to guess 1997-2000 idle at 725, and all later years idle at 800 RPM.

Both, but most importantly in gear
My wifes car has stock heads and cam, and after her "tune" it idles right around 600, which makes the "LS1 surge" a lot more evident
