Transaction No.: 2066852/4
Release date: 03-Oct-2023
Customer statement / workshop findings
Customer complains of poor quality music output from the shaker speaker due to a rattling noise/sound distortion
Technical background
There have been instances where shaker speakers have been changed under warranty for the complaint of sound distortion, yet when tested by
Bentley motors and the supplier, no fault could be found with the returned unit
Production change
Not applicable
Measure
To ascertain the difference between distortion or a rattle emanating from a loose/surrounding component
Or
The shaker speaker itself is incorrectly secured and/or at fault please conduct the following steps before replacing any components
1) Confirm the customer complaint by attempting to replicate the issue
NOTE: The operative must only continue with the next steps if the symptom/customer complaint is as described and can be
replicated
2) Navigate to the HMI sound settings
•
Take photographs of the customer settings (when the customer complaint is evident)
Operate the audio system ensuring the customers music source e.g USB stick and settings are applied/duplicated
•
Record a clear video of the issue and HMI settings, save a copy of the video titled - Noise prior to HMI adjustments
•
Make adjustments to the HMI settings to reduce any excessive maximum settings
•
Recheck to confirm if the complaint can be replicated after adjusting the HMI settings, if the complaint is no longer present, please advise
the customer accordingly
•
Record a second video, save a copy of the video titled - No noise post HMI adjustments
•
Submit both videos via a Technical DISS query stating the issue is no longer evident after the HMI settings have been adjusted and the
customer has been advised accordingly
However
If the issue is still present after the HMI settings have been adjusted, please complete the next steps until completion
Operate the audio system ensuring the customers music source e.g USB stick and settings are applied/duplicated
•
Record a video of the affected shaker speaker, save a copy of the video titled - Noise with shaker speaker mounted
3) Referring to Rep.Gr 91 - Gain access to the applicable front shaker speaker
Before any work is carried out on the seat, refer to "Precautions - Passive restraint systems and components
