Reason for block
Complaint:
Intermittent vibration noises can be heard from the woofer in the driver or passenger door.
Attachments
Cause:
The magnets of the woofer in the R171 do not always have a uniform black surface. So that these magnets are not visible through the speaker covers
(speaker grilles), black self-adhesive stickers have been affixed to them. Sometimes these black stickers become detached and can cause vibration noises.
Remedy:
Completely remove the black sticker from the magnet of the woofer. Any areas that are visible through the speaker covers (speaker grilles) must be
colored black.
