VW dealers sometimes give you the wrong sensor when you replace the high
pressure one. If you still have the original sensors, try putting them
back in.
Find the connectors in the engine compartment for both sensors,
disconnect them and use an ohm/continuity meter to see what they are doing
with the engine off and running at various speeds. One is normally open
the other normally closed. See the Bentley.
It doesn't seem that work on the engine should have changed the
connection at the instrument cluster.
With some determination, a pressure meter, an ohm meter, and a
bicycle pump, a person can check the operation of a pressure sensor. :-)
