AC Squeak & low growl

Rake · 02-14-2024, 11:50 AM

2014 X1 with ~123k miles. At low speeds I notice a low growl from the AC, I believe its the AC because when I turn it off the growling goes away. Additionally there is a squeak when the fan speed is low, the squeak is still present when the fan speed is increased but not as noticeable. I recently had to change out a wastegate actuator and looked inside the blower cage and saw no debris present. Any thoughts as to what may be causing these issues?

AC noise is indeed AC noise, most, if not all X1's experience this. I have it too.

Mine also makes a low-pitched growl when the A/C compressor has just started running. However, the squeak and the growl may be separate noises. I'd guess that the squeak may be coming from the belt or tensioner due to the increased load running the A/C system, especially if the belt is older.
