Z4 2.2 ENGINE RATTLE WHEN COLD

[TIMZ4]

WHEN I START MY 2.2 Z4 FROM COLD IT STARTS IMMEDATLY WITH NO ENGINE NOISE BUT AFTER A MINUTE OR SO THE ENGINE SPEED DROPS AND IT SOUNDS "TAPERTY" UNTILL IT WARMS UP(AROUND FIVE TO TEN MINUTES)THEN IT IS FINE. IS THIS NORMAL?

THANKS

Mum drives one of these and it doesn't rattle when cold and nor does the car
