Technical product information
Speaker Replacement - Diagnostic checks
Transaction No.: 2036678/2
Customer statement / workshop findings
Audio output from speakers is distorted
Technical background
There have been instances where door speakers have been changed under warranty for the complaint of sound distortion, yet when tested by
ourselves and the supplier, no fault could be found with the returned unit.
Production change
All speakers are subjected to a dynamic test and the individual results recorded for future reference
Measure
To ascertain the difference between a distortion or rattle emanating from a loose component in the door, an incorrectly secured door pad or the
speaker itself having a fault, would you please make the following checks before changing any components:
1. Remove the door pad and retest the speaker (door mounted) to the same audio level. If the noise or distortion disappears then check the
door pad and it’s mounting points for a poor fit or loose components.
2. If the speaker is still noisy then remove the speaker from its mountings and whilst hand held retest to the same audio level. During this test
it is important that the speaker be held away from its mounting points.
3. If the speaker is not noisy or distorting then please refit the speaker into its mountings. Check for any mechanical foul on the speaker body
and that the fixings are tight.
4. If the speaker is still noisy when away from its mount, then it should be replaced and the displaced part be returned to Bentley, via the
quality parts return system.
If the tests do not indicate a faulty speaker and you cannot locate a loose component then request support, describe the customer fault and your
initial findings via DISS in detail
Can you please ensure that this important procedural change is communicated to your workshop staff
