Condition
The subwoofer speakers in the front doors make scraping noises with bass-heavy songs or spoken passages.
Vehicles with the B&O sound system, PR code 9VS, are affected.

Technical Background
The speaker can have a hardware restriction which causes a noise similar to a blown speaker.

Production Solution
Hardware improvement introduced into series production.

Service
1. Check whether the complaint is caused by the speaker or by adjacent components (door trim, plastic parts,
cables, and etc.).
2. Follow TSB 2018187 “91 Sound system: speaker rattles, vibrations or audio interference” and ensure there are
no outside influences that can be removed to fix the noise concern.
3. If no outside influence can be determined, then remove the speaker from its mounting location using the repair
instructions in ElsaPro: Repair manual >> Electrical System >> Communication >> 91 Communication >>
Sound System >> Left Front Bass Speaker -R21-/Right Front Bass Speaker -R23-, Removing and Installing >>

 Keep the speaker wiring connected and play audio through the MMI while the speaker is removed from its
mounting location and while being held.
 Verify the noise is heard when holding the speaker in hand.
 If it is determined the speaker is the source of the noise, then replace the speaker.
