Wait...
i just read this and it seems a bit odd or a bit confusing
Quote:
NOTE
• A mechanical ticking noise from the High
Pressure Fuel Pump Assembly is normal
during Direct Injection system operation.
• This bulletin should only be performed if
an abnormal high pitch chirp or squeak
noise from the High Pressure Fuel Pump
is verified.

so whats the difference? is there always going to be a chirp/squek noise?
