Golf with about 65k gave me this code over the weekend with “o2 sensor stuck rich” I’m pretty sure this would be covered by the emissions warranty but I’m not sure if it’s worth the hassle of two Saturdays at the dealership (they never have the parts needed in stock) when a Bosch equivalent sensor is $55 and I could get it done quickly. Could it really just be the o2 sensor?

Beware of Bosch so called replacement 02 replacement stuff, my experience is they don;t last. get it replaced by VW under warranty for free.

The correct Bosch sensor will be more than $55, that sounds like one of the universal "cut 'n splice" types, which won't work. The correct one can be had for about $100 though, dealer list may be a bit higher. 03L-906-262-Q.
However, that may not even be the problem. Exhaust leaks can cause some strange behavior that the sensor (which is comparing the oxygen content of the exhaust with that of the air surrounding it) may send a signal to the ECU that is interpreted in a certain manner.
There is a trouble shooting procedure (VAG calls it Guided Fault Finding) that I would want to run through to at least make sure something else is not the cause... like a mouse chewed through a wire... which we are seeing almost daily now. We call them Covid Cars (cars that have been sitting). All kinds of issues crop up when you do NOT drive your car regularly.

Ironically, this is a car that DOES get driven regularly, however, it's almost always on battery power, so the ICE was never firing up to scare the critter(s) away)
