Can you PM me the service info/ part no?

Meaning unbolt it from the flywheel and rotate it, rebolt it to the flywheel. This fixes it. FYI this only affects Auto cars, not manuals.

Hi just so I understand, there's also a different "rattling" sound originating from the transmissions of automatic cars different from the waste gate/turbo rattling that affects these cars?

Yes, its more of a knock noise then a rattle
