Rear parking sensor beep

[JMMT]

Hi. The rear beep of my 2006 California T5 parking sensors is very low. Can anyone tell me where is that beep located? Thanks

I cant find any evidence of anyone giving the exact location. Mine doesnt sound at all so I can't even follow my ear. Every thread or link ends in a dead end.. Did you have any joy ?
