VW Passat B5 belt noise

Hi Guys,

Once again having issues with my Passat. Around 6 months ago my Passat began making weird high pitch noise coming fro the engine, it was the drive belt and it only happen rarely but as time went it would happen more often. Usually while engine is cold once warmed up it would go away. Now it stays even if the engine is hot.

The noise itself sound high pitch and pulsing and quite loud, you could say it's like a squeal.

I think it's coming from the area I have highlighted in the image.

Any suggestions?

Here in US, we did not get that motor in the B5 Passat that I am aware of. That diagram is a trip. I think that is the most convoluted belt routing diagram I have ever seen. That is asking alot of one belt.
