Original publication.

Customer states there is a noise from the clutch, transmission or driveline components under varying
driving conditions with varying sound levels.

Technical Background
To insure proper diagnosis and repair of customer concerns related to clutch, transmission and driveline
noises, Volkswagen Group of America is providing the following diagnostic steps.
1. Whenever possible, road test the vehicle with the customer. This will insure the technician understands
the customer concern and what it takes to duplicate for further diagnosis.
2. Once the customer concern has been duplicated, try comparing the noise to a known good vehicle
under the same driving conditions (hot/cold, uphill/downhill, accelerating/decelerating, etc.).
Tip:
If possible use a similar model with comparable mileage.

3. If the customer concern is deemed to be abnormal, try using chassis ears and/or stethoscope to
pinpoint the noise.
4. Once the location of the noise is found, attempt to record the noise as a sound file or video and contact
the Volkswagen Technician Helpline for further instruction.
Note:
Ensure the sound file and/or video are uploaded to the Volkswagen Technician Helpline case. Not
doing so will cause downtime on diagnostic help and repair advice.
5. If the noise is not easily duplicated, the source location cannot be found, or the technician suspects the
noise may be normal operation; contact the Volkswagen Technician Helpline with the following
information:
 Is the transmission/engine making contact with any components it should not be like hoses or
mounts?
 Can the noise be duplicated?
 What are the conditions, does the noise happen transmission warm/cold or engine warm/cold?
 Is the noise gear specific?
 Does the noise change when turning?
 Type of noise (click, knock, grind, etc.)
 Does the noise change with clutch position?
 Is the noise present on acceleration, deceleration, or both?
 If possible, provide a sound or video recording of the noise.
6. If necessary, the Volkswagen Technical Consultant can use this information to escalate the VTA case
to a QTM to assist in diagnosis.
