I brought my Model X to the Service Center last week to fix this issue plus a few others. When my advisor called me today to pick up the car, he said that they were unable to reproduce the sound. I insisted that the problem existed, and that he should have someone drive the car around in today's 100-degree heat for 15-30 minutes.
And indeed, after someone drove the car for about 20 minutes, the hollow metallic vibration from the A/C was heard. Lo and behold, after investigating the noise, the technicians discovered that those high pressure lines were crossed at the condenser!
My advisor admitted that I had told him this was likely the problem when I dropped off the car, and he said he's going to make sure all of his personnel are aware of this potential issue. He also said the vehicle's A/C should work more efficiently now as well.
Moral of the story? If you have this problem, don't pick up your car until the Service Center has looked at your A/C lines!
Foxxy and Blastphemy, which service centers are you guys using? I just got my car back from the Burbank Service Center and they said that my VIN was not affected by the crossed condenser lines according to a service bulletin. Also, they pulled the logs, but nothing was out of the ordinary. My fan is loud and my energy usage is over 400 WH/mile these days in 80-85 degree weather (90D). I do hear a weird bearing type of noise occasionally so I am worried about both efficiency and about the life of the AC system. If you have better luck at other Service Centers, let me know.
