Grinding/squeaking/not a good sound coming from engine

[olgunan]

Gents,

I noticed Thursday that my 07 X5 4.8i with 60k started making an odd sound. I didn't really think anything of it until I heard it again Friday when I went to work. I drove home after and the sound was the same and started it up again last night and it was ridiculous!

It is coming from the left side of the engine down by the AC compressor. It literally sounds like a rod or something internal has been thrown, but I checked the oil and I didn't notice any shavings and the car still runs like a champ and there are no lights on. Looking under the hood I noticed a lot of oily residue and metal shavings down near the AC unit. I am thinking a bearing in the AC compressor has failed and causing the sound. Cycling the AC on and off didn't really make a difference and it is still blowing cold!

I had it towed through BMW Assistance to the nearest dealership which is 160miles from my house. I have a CPO and just wondering if you all think that an AC compressor would be covered and has anyone else experienced this.

This is the first time that I am using the warranty an didn't really no the ropes and gotchas with it.
