Pulley Squeaking when Turning On the A/C
Sup Guys,
I own a 2010 E70 X5 4.8i. Last couple of weeks i have been getting a loud squeaking noise coming from the pulley/belts area every time i turn on the A/C when i turn on the car. The squeaking appears to stop once i turn off the A/C or after about 10 minutes of driving. Anyone have any idea what it could be? I tried using held conditioner but it didn't seem to do anything. Any help would be greatly appreciated.

Could also be an idler or tensioner pulley.

The idler(called deflection here) looks to be #6.

Just recently went through something similar on my 11 35i, I had to replace the tensioner pulley. While doing so I replaced the serpentine (driveshaft) belt and the other pulleys done there. No issue ever since I made the repairmen in those areas, hope this helps!
