Yes, it is normal for BMW Z4s to make a rattling noise when idling. This noise is caused by the idle air control valve, which regulates the air flow into the engine. It is a common issue with BMW Z4s and does not affect the performance of the car.

It's always a good idea to get your car checked by a professional if you notice any unusual noises. While it may be a common issue, it's best to have a mechanic take a look to ensure everything is functioning properly.
