Condition
Customer states:
• Whirring/ringing noises when accelerating at engine RPM between 2000 and 2500 rpm.
Workshop findings:

Noise complaint can be duplicated and sounds like a whirring/ringing noise produced by a metal panel.

Technical Background
Due to tight component tolerances, vibrations may occur under specific loads and engine RPM ranges and result
in minimal contact between the exhaust manifold heat shields and the exhaust manifolds.

Production Solution
Not Applicable

Service
If the customer complaint is similar to the noise which can be heard after 12-13 seconds in example video 1,

If there is a similar noise issue with the heat shields, the affected heat shield must be adjusted (while still
installed) to allow for greater clearance between the heatshield and the exhaust manifold.
