VIDEO: Buzzing / humming noise near passenger side of engine

VIDEO:

Title says it all, lately I've been hearing this buzzing / humming noise on the left side of the engine. The first time I ever heard it was when I got a 30FF code due to what I believe were incorrect JB4 settings. I also had a 3EF4 code (thermostat) but I believe it was just a fluke.

The noise sounds like it's coming from the boost solenoids.

Is this anything to worry about?

Has anyone experienced this noise before?

Thanks

Boost solenoids. Replace both if you have never touched them. There are multiple part number revisions for them.

Already had the pleasure of dealing with that lol. Replaced about 7,000 KMS ago.

Any harm in just replacing the faulty one for the moment?

Is there any chance this is causing my wastegates to rattle a little more than usual? Could this be affecting my boost? The car felt a little sluggish the last couple of times that I drove it, but I just assumed it might be the usual heatsoak that I experience..

Yes this could be exactly why.
