Owners of 2008-2010 VW vehicles equipped with the 2.0L engine may complain of a rattling noise from the engine or exhaust area while accelerating from 1,800 to 3,000 rpm. In order to complete proper diagnosis and ensure that the noise is coming from the turbocharger, use the following procedure:
If, after attaching the weight to the actuator rod, the noise is quieter or has changed in pitch, DO NOT replace the turbocharger. Remove the wheel weight, create a VTA ticket in ElsaWeb and contact the Volkswagen Technical Helpline at 800-678-2389. If after attaching the weight to the actuator rod and the noise has not changed, remove the weight and continue diagnosis and repair as necessary.
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 converter and can be misdiagnosed as a loud converter.
