2004 Jetta 2.0
Does this relate to the O2 Sensor, and if so, is it the one before the cat. convert. or after?
Thanks for your input.

Check to see if yo have a green top coolant temp sensor. That is most likely your culprit. Being a 2004, isnt it under warranty anyway? Whatever the case, check to see if you have the black one or the green one. If you have the black one, get the green one, its only like6 bucks and takes like 2 min to install.
its definatly the sensor if its black. If it was a green one then a new sensor would need to be put in and a new T stat for that fault code.
Also if it was a green sensor and freeze frame data shows -40C then just a sensor is needed.
