What can I expect to pay to have this replaced (parts and labor)?

furthering the Search reveals the best answer is to make sure all your vacuum lines are not dried out, cracked open, and are secure. You will then note using the Search feature that replacing the pre-cat o2 sensor usually solves your fault code. Using the Search feature yet again easily explains that the cost varies wildly depending on if you DIY or not. Various online sources for obtaining an o2 sensor abound using the Search feature.

you're the polar opposite of the dude banned from the B5 A6 forum a couple of years ago, for uncontrolled rage whenever a noob posted a question that had already been discussed, anytime since 1982!

Congrats!!!

I propose a new acronym in your honor:

Dear poster, please "UTEACSF" <use the easy and convenient search feature!!> thank you!

I did use the search feature ... didn't find any post or thread indicating what owners paid to get it repaired (parts and labor).

Thanks for the repeat info.
