Driving with a faulty O2 sensor means the computer won’t be getting the correct reading of the mixture and hence it won’t be able to adjust the air-fuel mixture properly. But if your engine starts and runs, and can stay running, it’s drivable.

How do I know if I need to replace my 02 sensor?

I have just ran it through my diagnostic and have the following fault codes:

How does the O2 sensor on a Volkswagen work?

Your Volkswagen’s oxygen sensors are basically monitors with the tip inside the exhaust pipe to detect the oxygen levels in the exhaust. If too much oxygen is running through the exhaust, the system is running too lean — too little and it’s running rich.
