Best place is the VAG-COM support list:

In your case, though, the faults are fairly self-descriptive.

It's possible that the connector to one of your oxygen sensors
has become disconnected.  Because it is just a bit coincidental
that the heater filament of the sensor and the sensor element itself
would both fail at the same time.

B1 S2 stands for "bank 1, sensor 2".  I think bank 1 is the left
(US driver's) side of the engine, sensor 2 is the post-cat sensor.
Don't quote me on that though.  Someone please correct me if I am
wrong.

Maybe, or possibly an electrical contact problem too.  If you have the
Bentley repair manual then you could look up where the F129 switch is.
