SERVICE PROCEDURE
1.
If a whine/whistle is present, use WDS datalogger active command function to open the EGR valve, or unplug the variable geometry turbo (VGT)

Listening device (vacuum hose, etc).

Smoke from a smoke machine (Rotunda 218-00001 or equivalent) introduced into the exhaust pressure (EP) sensor tube.

CALIBRATING THE SMOKE MACHINE IS NOT NECESSARY.
