Like John said, get the oil level down, and check the connection near the
crank pulley.  That is a harsh environment for the wire and connector.  The
sensors can also go bad.  Getting it out can be interesting.  You can check
its operation with a bicycle pump and an ohmmeter.  It should be the one
that triggers at 0.9 bar.  VW parts depts. often give you the wrong one and
this causes a lot of unnecessary buzzing and worry.   BTDT
