Update of my car dashboard rattling problem. Found and solved with accessories shop in the sunday afternoon. Its a small gap near passenger A pillar and windscreen, everytime go through bumpy road the dashboard will hit the windscreen and create rattling noise. Solution is sumbat in a sponge to hold the gap, a bit ugly but acceptable better than the annoying 'tuk tuk' sound. Found a good accessories shop with a very nice guy worker. Hard time to find the rattling area, bring the acc guy sit beside me to round and purposely go through bumpy road. What he did was removed the glovebox and use his handphone to take picture inside the dashboard with flash. Slowly minimize the problem area by using fingers to press the possible area, if press hold the right place and the rattling stop then that was the problem cause area. Mr nice chatty guy talking about all sorts of car problem all the way and charged me rm10 only for the sponge tape and the problem solved.  Sigh proton..famous iriz problem still no improvement, there are sponge originally at the gap but not thick enough to insulate.

Thanks for sharing , looks interesting .

Omg after fixing the dashboard, I can't find anything to complain about this car. Absolute pleasure experience!
