Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

The owner wanted me to take a look at the cabin noise.
One of the cause was the rattling boxes and wires behind the
centre console around the heater unit.

Normally, I’m quite happy to disconnect any connectors and
re-rote the cables but as these could be for the security devices,
it is too risky for me to just start disconnecting any of the connectors
without knowing the system architecture or wiring diagram.

I could end up not being able to start the engine again.

Spoke with the owner over the phone and decided to leave them
as they are for the time being and the owner will find out what kind of
aftermarket devices they are so that we can deal with them in the future.






Rattling noise from the ceiling.
During the test driving session, I felt the noise was cabin temperature dependent
but none-the-less, decided to remove the ceiling panel.

While the rear end was secured really well, the left side above the
passenger seat was somewhat solid and felt strange.
Found out that instead of using the clip, some sort of big sticky block was
placed at the bracket. No clip at the bracket.
Not good.




More wires around the door molding.






Replaced all clips and back in place.




As seen on many NSX, the clips at the rear upper trim were dead.
In fact, someone used aftermarket different shaped ones.
Replaced them with the proper OEM one.



Quick test driving session to check for the noise and happy with it
although it is more of temperature dependent type issue.



Although the tyre pressure was adjusted several times,
the temperature has dropped significantly so hope the owner will
adjust it again once the weather gets warmer.






Dressed the engine, washed the car, quick blow dry followed by
short driving and ready to be returned to the owner.



Thank you for using my service and apology for the extra delay.

Regards,
Kaz
