As in the recent post, started servicing another NSX.
This is the 1st of the 3 NSX with the same service menu for the efficiency and finger sensitivity purpose.
Big thank you to the owner with the cooling system service letting this owner being served first.
I would have done the same.

Tried to capture the intermittent [BRAKE LAMP] warning but obviously, it won't happen when I wanted.
It happened just when I wanted to take the car out of the garage.
By the time I went back inside the garage to get the tool to hold the brake pedal, no longer be able to reproduce the same issue.
The owner is already aware of this and on the way to my place, confirmed by his friend driving behind in the 2nd car that it was genuinely caused by the partially dead lightbulb or socket.
He noticed that from time to time, one of the brake lightbulb at the left side didn.t work.
The gauge cluster was already refurbished by me years ago and the warning only triggered after pressing on the brake pedal so not the gauge cluster issue.
I will probably replace all 4 brake lightbulbs (JDM) on this occasion.

Hope it's nothing to do with several extra wires running behind the carpet inside the boot….

The owner told me that he re-charged the a/c refrigerant twice but only lasted few days.
And the a/c specialist was someone following the rule.
He told the owner that he would not be able to charge the system if there was obvious leakage detected.
And it was already re-charged twice yet the owner told me that it only lasted few days.
So, connected the manifold gauge and somewhat expected, it was completely empty.
From all the info I have, I suspect it's leaking from the compressor seal or the schrador valve.
If the refrigerant escaped within few days and with such huge leakage, the specialist would have detected so very unlikely to be damaged pipe or fitting o-ring issue.
Still, I'll give a good look.

Wanted to carry out the vacuum check but must replace this hose gasket first.
(The red panel is my tool box, not the body work.)
Didn't like how it looked and ran out of the new one but easily found verywhere.
I must have overtighten the fitting last time.
Very unlikely but just hope the leakage is not happening at the evaporator.
It happened on my NSX.
Whole dashboard must come out from the cabin.
As I need removing the blower fan motor for the ABS Upgrade, I'll first start with the inspection of the evaporator.
As a side note, it's important to use the A/C regularly to oil the seal and o-ring around the system.
The oil travels throughout the system via refrigerant and that's why when you have system leakage, you will lose the compressor oil as well.
If the compressor was not engaged for months/years, the refrigerant will escape from the compressor front/rear seals.

Just like this one.
With the same photo, tried showing that it still has the original WP but not great camera angle.
