Univ Bosch OXS sensor in 12v6???

[Dupree, Jim]

Many Bosch Oxy Sensors are what Bosch calls 'submersable'. The sensor
housing is completely sealed and the harness is sealed to the housing. An
oxygen sensor needs out side air (reference air) in order to get a proper
oxygen content deferential between exhaust gases and the outside air. The
bigger the difference in oxygen between inside the exhaust and the outside
reference air the higher the voltage signal the sensor creates. The
'submersible' sensors get their reference air through the wiring harness.
Part of the reasoning for this type of sensor is to reduce the contamination
of sensors from the outside environment that the exhaust system is subject
to. Porsche recommends against universal sensors where a 'submersible'
sensor is used.
Is the sensor used on the Audi 12V V6 a 'submersible' sensor, I don't know?
I would guess it is.  Would I use a universal to save a few $$, quite
possibly. Would I sell and install one on a customers car, NO.

Thanks
Jim

Yes, absolutely, all Bosch sensors are basically the same, you pay $150+ for
the harness..
