Are O2 sensors (like timing belts) subject to time limitations?

the hard thing with that>>>>
is that the performance slowly degrades and you do not notice the difference until a fresh set go in. While it should perform close to 100% for the better part of its life, it does not appear to...at least that has been my experience with these things.....
I treat them more like a spark plug on the 1.8t....mine should be good for another 40k or so....

likely true, but with my stock 180 motor, i couldn't tell a drastic difference even
replacing it after the old one had thrown the code.
Probably the engine management is less able to adapt to a worn O2 sensor when it's already running on the edge of its capabilities.... i.e. chip, boost machine, etc
