General 1.4L Multiair Pop squealing noise

[arekp]

Recently noticed an intermittent squealing / whistling noise from the engine bay. Can't pin point which region it is coming from.

I typically hear it at idle eg when stopped at traffic lights with AC turned on or off. Never heard it during driving, perhaps due to engine noise.

Timing belt, accessories belt, tensioner about 3 years old.

No error codes with MultiECUScan.

Video attached - AC was off for the video.

Any suggestions where this could be coming from?

Sounds like a tensioner bearing , possibly on the guide for the auxilary belts, assuming no belts loose.
You could try spraying something like WD40 in the area noise is coming from to locate better.
Note it is not a cure and will soon wear off. Don't get it in your eyes whilst looking in that area.
