Technical product information
Interior trim - Creak and rattle - Noise identification

Transaction No.: 2056582/3
Release date: 03-Jul-2020

Customer statement / workshop findings
Customer statement:
Noise complaint from the interior
Workshop findings:
The noise can be reproduced and clearly assigned to the interior
Prior to starting the instructions within this TPI, the Retailer must check and confirm the vehicle is in standard factory condition and has not had
any non-approved aftermarket modifications conducted
Should any aftermarket modifications be found, the Retailer must make Product Support aware by raising a DISS query to report the details of
the modification, you must then await feedback from Product Support before conducting any further work

Technical background
It is the retailers responsibility to check and confirm if there are any TPI’s which are applicable to the customers
complaint/issue if there is an applicable TPI available, apply it and complete a DISS complaint to include ‘Workshop findings’ only (
No repair query required)
For correct diagnosis and repair the attached Flowchart must be followed in conjunction with the Measure section of this TPI

Production change
Not applicable

Measure
1) Carry out a visual inspection of the interior to confirm the location of the noise
If the noise cannot easily located carry out the remaining instructions from Step 2
2) In the event an interior noise is present for example creak, squeak, rattle, and the operative CAN NOT locate the issue by conducting a visual
inspection you must capture/record the noise.
•

Should the noise be frequency related for example a tizzing/vibration noise a frequency recording will be required

•

Refer to the onward instructions depending on which type of noise is evident (creaking or frequency related)

IMPORTANT: For frequency analysis and noise recording we recommend using the Chassis Ear Tool WT 10437
Record the noise and measure the frequency using WT 10437 Chassis Ear Tool - Follow the instructions within this TPI in
conjunction with the WT 10437 user instructions
3) Referring to Figure 1 - Using the sensor clamp/s (Point A) and Bluetooth module/s (Point B) provided in the kit - Record the noise

Figure 1
TIP: In order to locate the noise it could be necessary to use multiple clamp and module assemblies, the operative must refer to the appropriate
user instructions

WARNING
IMPORTANT: The driver's concentration MUST be focused on the road at ALL times the assistance of a second technician is
required
WARNING
Observe all road safety procedures and speed limits.
TIP: To capture the frequency - Select ‘FFT Graph’ as Wave Form Type (Figure 2) and read the peak achieved during the recording as
highlighted in Figure 2 (in this EXAMPLE the frequency is 2000Hz)

Figure 2
4) Once recorded - Save the file to your device.
NOTE: The sound recording/video can also be taken from a mobile telephone as long as the noise is clearly identifiable
TIP: If the noise cannot be reproduced a customer recording of the noise would also be acceptable.
Should there be no applicable TPI’s, and you are not able to identify the source of the noise by using WT 10437, proceed to Step 5
5) Raise a DISS technical query – The creak and rattle questionnaire (attached Excel spreadsheet) and the sound/video recording must be
attached to the open DISS query
VERY IMPORTANT: NOISE RELATED DISS QUERIES SHOULD NOT BE SUBMITTED WITHOUT AT LEAST TWO
ATTACHMENTS, SHOULD THE REQUIRED INFORMATION NOT BE INCLUDED, THE QUERY WILL BE RETURNED TO THE
RETAILER
