B58 chirp

Anyone else getting chirp from their B58 on a cold start? BRZ/FRS used to be (maybe still are?) notorious for this as it had to do with the high pressure fuel system. I don't know if it's a similar thing on these engines, but I just noticed it today.

Not my video, but same noise:

Mine does this too. It sounded like a squeaky pulley to me so thanks for posting this.

There's a chirp noise heard on some B58's while accelerating. Not sure that this is that tho

It's normal. Even my X3 M40i does it.
