Noisy whistle when x3 AC is on

JK479 · Today, 11:06 AM

Currently about to buy that x3 35i. On the test drive I observed a rather noisy whistle which I located coming from the HVAC vents.

Is this a tell tale sign it will need an AC air compressor?

Curious if anyone had this happen yet?

I'm not sure about a whistle, but I've heard conflicting information on the "whine" the compressor makes. Some people say it's happened to them for years and BMW says it's normal, others say it just needs a refill and the noise will go away.

Unsure if this is what you mean or not.
