Rattling noise from under the front seat/s (sound system at high volume) - Naim audio system only
Transaction No.: 2070142/1
Customer statement / workshop findings
Customer statement
Rattling noise from under the front seat when the sound system is playing at high volume (Naim audio system only)
Workshop findings
The issue described is evident however no DTC's are stored
Technical background
The "shaker" speakers are fitted on the underside of each front seat frame (New GT and New GTC)
Note: At high volume and with the bass tonal control set at maximum the bass shaker is being over driven (music dependent) this results in the
leaf spring subsequently within the speaker breaking which causes the rattle noise from under one or both front seats
In the event the symptom is as described the operative must conduct the instructions within the Measure section to completion
Production change
In the event the issue is evident post VIN SCBDX33S3PC008987 the operative must raise a Technical DISS query and await feedback before
conducting any further work
Measure
1) Obtain a clear video of the speaker which is exhibiting the issue
•
Attach the video to a non technical DISS query ensuring the faulty speaker(s) are clearly identified as faulty
2) Referring to Rep.Gr 91 - Replace the applicable shaker speaker
3) Using ODIS Check the part number of the amplifier using ODIS (address 47)
In the event the amplifier is A suffix the amplifier must be replaced - Refer to Rep.Gr 91 - Multimedia system. Digital sound package control unit
J525 using the C suffix part, once replaced the software update from step 4 must then be conducted
However
In the event the amplifier is already at B or C suffix, the software update from step 4 can be conducted

•
Connect a suitable battery charger to the vehicle, for further information refer to the Repair manual

Because of the highest transmission stability you MUST use the diagnosis interface VAS 6154 (WiFi diagnostic tool)
ONLY in USB operation or the cable-connected VAS 5055 for the reprogramming (updating) of control units. If these
units are not available, the diagnosis interface VAS 5054 (A) can also be used in USB mode
•
Do Not under any circumstances use a Bluetooth connection to conduct the reprogramming (updating) of control units
4) Select and run Guided fault finding
CAUTION

Customer information
During the repair the amplifier software and tune has been updated to the latest level, aligning the vehicle to the current production software with
the latest available tonal tune
The shaker speakers are designed to give the feeling of bass in the low volume range. As the volume increases the Bass is then delivered by the
speakers giving a more natrual sound
