Welcome back! Mine were covered. There is a 7/70 emissions warranty on O2 sensors...
My dealer didn't even know about it. I called Audi of Canada, and the guy I spoke to initially didn't think they were covered. I pushed, and made him check. Sure enough they were covered, and he gave me a reference number to pass along to my service adviser. I wonder how many people pay out of pocket for this when they don't have to?
In speaking to others on this board about this, I've found that coverage on this in the US depends on which state you live in. Contact AOA and ask, but be pushy and don't accept a quick answer. Make them check.

Re: 2001 2.7T pulling codes: P1140, P1122, P1557, P0113. What to do?
I had to replace one of the O2 sensors on the 2.7T. My VAG-COM fault code pointed me to the passenger side post cat sensor (B1 S2). Under the hood, it's the GREEN connector. FYI the BROWN Connector is for the other post cat O2 Sensor. I disconnected that one as well, in order to pull both cables down to give me enough slack to remove sensor with a 22mm wrench. The cables are zip-tied together in two places and clipped to the transmission, which for me turned out to be the biggest PIA.
TOOLS/HELPFUL ITEMS:
* Jack or Ramps
* PB penetrating oil
* 22mm wrench
* Rubber hammer
* Zip-tie cutters
* Shop light or flashlight
* 10' of string (only if you want to save time)
* Tape (I put tape over the exposed electrical components on the connector while I was working and pulling it back through the car.)
* Zip-ties
* A new O2 sensor is probably a good idea to have before you start.
STEP BY STEP INSTRUCTIONS:
1. You'll need to either jack up the car or put in on ramps. I used a jack & stand.
2. Spray the O2 sensor to be removed with PB.
3. Disconnect the GREEN Connecter.
4. Spray the O2 sensor with PB again.
5. Tie some string around the Connector BEFORE YOU PULL IT so that it is easy to route the new cable back up. This will save you a LOT of time.
6. Still from under the hood, follow the cable down to where you should see the cables zip-tied together and clipped to the transmission. Pull the clip off and cut the zip-tie.
7. From under the car, reach up around where pictures 4,5, and 6 are all looking and find that zip-tie and clip so you can remove that and cut off zip-tie too.
8. Once you've separated the two O2 sensor cables, you can pull the GREEN connector and cable down through the car.
9. Remove the O2 Sensor with a 22mm wrench. Use more PB as necessary. One time I used an ice cube on the bolt/threaded part to help the removal process. This time I used PB and tapped it loose with a rubber hammer.
10. I pre-wound the cable in such a way that when installed it would want to turn with the wrench and not just twist up and bind with the possibility of damaging the wires in the new cable.
11. Install the new sensor and tighten with 22mm wrench.
12. Zip-tie the cables back together and clip them back in place.
13. Pull the string from under the hood and pull the Connector back up through the car, if you didn't use the string, here is where you'll need more beer so you don't give up, and try to find a neighbor kid or someone with a long skinny arm to help you.
14. Zip-tie the cables together and clip back in place.
15. Remove the tape and string.
16. Connect the GREEN Connectors together.
Good Luck!
