Hi DALE,HERE'S A LINK TO YOUR CODE AND POSSIBLE CAUSES,THE SENSOR IS BANK I,SENSOR,WHICH MEANS IT'S ON THE SIDE WITH CYLINDER I AND 2 SENSOR WHICH IS LOCATED BY CATALATIC CONVERTER,HERE'S A LINK TO YOUR FIRING ORDER.fIRST LOOK AT SENSOR AND WIRING TO SEE IF ANYTHING IS OUT OF PLACE,LOOSE WIRE OR DAMAGED SENSOR,ALWAYS USE EXACT FIT ONES,NO WIRE SPLICING.2004 Volkswagen Passat 2.8L SFI DOHC 6cyl

BANK ONE IS THE REAR BANK OF CYLINDERS AND TWO THE FRONT BANK

Honestly it is not very expensive to replace, but it is not extremely important. What it does is measure the oxygen/fuel level coming out of the engine. This tells the computer that the engine is either using the right air/fuel mixture or allows the computer to change the mixture slightly to allow the car to run properly. You could pull the sensor out and clean the terminal as it usually has alot of carbon build up due to its location, but this is normally a temporary fix. I hope this helps you with your problem.
SOURCE: What does the oxygen sensors look like in a 2003
There should be an O2 sensor before and after the catalytic converter on your vehicle, so it will have 2 sensors. You'll need a 7/8" open end wrench or an O2 sensor socket to replace them.
It'll look something like this: http://www.carsteering.com/data/all_images/48-01718.jpg
