Hey guys, sorry for the late follow up to my original post. I took it into the dealer and they acknowledged the noise (hard not to). They had a regional tech (I believe) look at the motor and listen with a scope, but they couldn't pinpoint the exact spot of the noise. They told me to keep driving the car and to let them know if the sound got worse. It has gotten worse, in fact; it's much more frequent and noticeable, so I'll call my SA tomorrow. Additionally, the whine this motor has, which was already significantly louder than my last S65, is getting louder.
Regarding this...My sound isn't rhythmic. It's constant, but not consistent. Is how mine sounds a precursor to this video?
