2021 R with 6500 miles. I noticed today that on idle after the car was driven, a slight metallic tapping sound. I realized it when I opened the door and the car was still running. It's most notable from under the car on the drivers side. When the hood is opened I can not hear it from the engine bay over the general sound of the engine running. It's not the injectors sound as it is a slower pace sound. I attached a video. If you listen carefully and try to tune out the regular injectors noise, you can make it out easily. I'm not sure if this was always there or not but I just happened to realize it today. Does this sound like normal idling?
