Rattling Noises from Engine Compartment Area or Exhaust System
Customers may complain of a rattling noise from engine or exhaust area while accelerating from 1800-3000 RPM.
In order to complete proper diagnosis and ensure that the noise is coming from the turbocharger, use the following procedure:
Ensure that there is no physical internal or external damage to the turbocharger. If no damage is observed, proceed to step 2.
2. Test drive the vehicle to duplicate and familiarize yourself with the noise. Noise can typically be duplicated by driving up a moderate incline, beginning at 35 mph in gear (manual or automatic transmission) and accelerating through the RPM range of 1800-3000 RPM under moderate to heavy throttle. Obey all local traffic laws.
Once you have confirmed and familiarized yourself with the noise, attach a 2 ounce wheel weight to the wastegate actuator rod (figure 1) and take the vehicle for another test drive.
If after attaching the weight to the actuator red the noise is quieter or has changed in pitch, DO NOT replace the turbocharger. Remove the weight, Create VTA ticket in ElsaWeb and Contact the Volkswagen Technical Helpline.
If after attaching the weight to the actuator rod the noise has not Changed. Remove the weight and Continue diagnosis and repair as necessary.
Note: Use caution when diagnosing the origin of the noise. Although the noise may be originating from the turbocharger, it can be amplified through resonance to the catalytic convener and be misdiagnosed as a loud converter.
Technical Background :
Because of exhaust gas pulsations the Wastegate flap and actuator rod vibrate at the introduction of boost pressure.

If you are experiencing this issue - I am posting an outline of steps you will want to take if you are not interested in modifying your engine to resolve this on your own - as I am many people out there are not.
Please email me for Bulletin - not having luck attaching it to this post - and i will email it to you.
