Hi,

recently i found out dat when i slow down my Evo 9 to ard 30-34km/h, there is a 'beep beep' sound.

im sure this sound is not from my defi oil press. cos oil press 'beep' sound is continous and the red light will light up but the sound i heard is just 'beep beep' and is softer then oil press 'beep' sound. this 'beep beep' sound can sometimes
be heard when i move off my car from stop. But it is always clearly heard when i step on my brakes and slow down my car.

the sound is quite irritating. kindly share with me if any of u hav encounter this sound b4 and how to get rid of it.

Electronics installed:

4 defi (water & oil temp, oil press & boost), AVCR, Apexi turbo timer

What could be the likely cause of this sound???

thks!!

 

Unhook power to the gauge you think is making the noise, see if it does it.
