hi guys, just got my viva, but i noticed one thing that is persistent, i hear a very annoying sound that comes from behind the dashboard, it's like someone shaking a bunch of keys together,any ideas what this could be? i went to the Perodua service center, they seem to have no clue about it, once the mechanic checked under my dashboard and said theres a gap causing the sound and he rectified it but the sound came back the next day, when i went back to the SC, did a testdrive with the mechanic and theres no sound and this problem comes and goes, however when i hit like a bump or go donwhill it'll start to sound like something is out of place.
