N55 PS2 Wategate rattle or something else?
2011 335 N55 New PS2 with 500 miles on it. When the engine is hot and at idle I hear a rattle that constantly varies in the same surging pattern louder then softer. If I rev the engine to about 1k rpm it gets a little louder and then you can't hear it at about 2k rpm and up. You can't hear this noise while driving. Wastegate rattle or something else? Any ideas? Thanks

Noise update...its the transmission
I did some more investigation and found the noise is actually coming from the transmission bell housing area. Its an automatic 6hp awd. Has anyone experienced this noise?
