Mine has started making the same noise. I first heard it about a year ago & the dealer said it was "not unusual". But I swear, the noise is so loud that it gets attention from pedestrians! It's a clacking sound that appears to be coming from the AC compressor. It only makes the sound when the AC or DEF is on, and increases in frequency (but not volume) when I accellerate. When I let off the gas, it "spins down" to nothing. Could this be the "magnet clutch" that my service manual references? If so, is it internal to the compressor, and more importantly, can it be fixed without replaceing the whole compressor for a thousand bucks? Any A/C guys out there?
