This has been going on for some time now, and I have been able to ignore up until now. So please is anyone knows what is making that high pitch squeaking sounds i would really appreciate it. It sounds like it might be a belt pulley or something?

Pull the belt an see what acts funny when you turn the pulley

 

Sounds like the serpentine belt tensioner might need replacement I had similar issue with my tt and that solved the problem

 

maybe the air pump ? or is that more of a high pitch whine?

 

I just got my whole belt done like 15,000 miles ago. It didnt make the noise at first, and then started all of the sudden
