Engine chirping / rubbing sound

[demarche]

Curious if anyone has any insight into what this sound originating from my engine might be.
Its a chirping or rubbing sound obvious at idle, regardless of AC on / off.
I first noticed it during a long roadtrip in hot weather, and it has persisted since.

Issue is currently under investigation with Toyota, TAS case number TA250480154.

This is on a 2024 off-road manual transmission.

The dealer seemed to suggest I was not the only one experiencing this issue.

Please see attached video for a clip of the sound.

Mechanic @ lexus dealership identified this sound as coming from the solenoid in the purge valve, have to try to get a Toyota dealer to replace now.

Is that diagnosis from a an in-person diagnosis or a lexus tech commenting on another forum?
Verify with stethoscope, or unplug it & verify noise is gone...

I stood with the lexus mechanic in front my engine while they used a stethoscope and manually unplugged & plugged back in the purge valve.

As a bandaid they actually sprayed some wd-40 in the valve which seemed to help somehwat.
