I also have similar sound - I think coming from the belts area. I just sent for 35k service at PE authorised SC on Saturday and I have no such problem before that. On Sunday only I noticed this problem. I just change the engine oil and asked them to repair the 'loose gear stick problem' - cost me RM8 for the broken spring. Not sure whether I have the time to back the car to SC to check on the rattling problem.
