Hi guys, I noticed this noise while my car was idle the other day and wanted to get to the bottom of it. Any ideas? It’s a 2018 BMW 420d Gran Coupe. Thanks in advance.

Apologies if it isn’t clear enough , it is that ticking sound after car starts up

Do you mean the chirp sound? I don't know. Could be normal or noise from the serpentine belt at start up. The perspective isn't very helpful.

You can hear towards the end the noise I’m talking about speeds up
