specifics from the SIB:

A slight rattle noise is considered normal operation of the mechanical wastegate valve and is not a failure of the part. No repair should be attempted for this type of rattling complaint.

If the noise is described as a clanking noise occurring up to six or seven times in a row during adeceleration from approximately 3,500 RPM, or during a heavy application of the accelerator without a drive gear being engaged, then continue with the procedures described in this document.
