engine rattle when cold

[thomson]

when i start my car when cold , put in D then I can hear a continuous "ta ta.." noise from the passenger side near glovebox, it goes away once i step on gas, but when i stop on first stop light the noise will be back. Put in neutral it will be gone again. Drive for awhile then the sound will be completely gone. Is this normal? I think I had the sound before but it only happens in extreme cold winter so I didn't care. But now the sound appear almost every time when I didn't have time to warm the car.

my car has ~64000 km now

is it some kinda metallic vibrating noise? 'cus I'm getting some weird noise too, when I put it to D and gas it a little, i hear it until the RPM goes up 1.5+K then it's gone, but comes back whenever I stop and gas on it again. But after warming up, it dissapears. I've had this same problem before, I replaced the tensioner pully from the TSB and the serpentine belt, but after a while it came back...

actually i fixed my problem after i took the owner manual out of the glovebox . Seems like it may be caused by the weight of glovebox and the engine idle vibration when the car is cold and in D. Also I suspected when I changed the cabin air filter I may not put back the glovebox correctly or broke something. Anyhow there's no more noise
