Noise when Idling

I just had that noise fixed. It drove me crazy. About half the time when I would start the X5, I would hear a fluctuating high pitch noise coming from the fan. I suppose it's was the Auto Climate control or whatever that makes the heater fan start when I start the engine. I always have to turn it off after I start. I've had it set at 75, on low, on both sides for the last month. Now that you've read my story, here is the solution that worked for me:

I called the dealer to complain (because it's CPO'd, I complain about every little thing). They took it for the day and told me it was the AC that needed to be charged! That sounded crazy to me since I haven't even used the AC yet (no need to in New Jersey yet), and the temp was always on 75. Anyway, they charged the AC, and that stopped the fluctuating noise!!!

Good luck with yours.
