Idle Drop!
Let me know if this is normal. When i'm at a light, my car usuallyidles at about 750 rpm(halfway between the first hash mark and the 1000 mark. Frequently it will drop to about 550-600 and seem like its going to stall out. Can this be fixed or is this normal.
Please advise.

extra load on the electrical system, car wants to idle normally, starts to lose it, and bumps up the idle to compensate for the load. Like if the AC kicks on, or cooling fans, stuff like that.

Until you eliminate the vacuum/boost leak or the dirty throttle body as a source, the rest of the realm of possibilities is mute. You need to exclude the most common/obvious first.

Occasionally the car (at least everyone I've ever owned) will simply drop or increase a couple of hundred RPM while idling and then return to bt 700-1000rpm. This should not happen everytime you are at a light though. Once in a while is acceptable but an unsteady idle as the norm is not. It still worth you're time though to check it out with a VAG-COM. If you don't have one you'll have to go to a dealer. If no fault codes are read you have nothing to worry about. I'm not sure what sensors Audi uses to control the idle but the VAG-COM will tell if one is wrong.
