That would be my guess.  I have had these leak on two different VWs.  It is
not always easy to see.  In the second case the oil was leaking down the
backside of the sensor (that is between the sensor and the block), so it was
very hard to see where it was coming from.  Apparently it is due to the
blade to the connector being metal and it being embedded in plastic.
Repeated heating and cooling and expanding/contracting at different rates
for different materials causes cracks.

Yes.  They measure two different pressure levels.
