The first code will show up anytime you disconnect the battery, don't worry about that one, just clear it.

That second code could be variety of things, depending on what engine you have. Are you a 2.8? If so, I think it's somewhat common and there was a recall for it, and you can find a lot about it if you search for "16795" on AudiWorld.
