Vibration while sitting idle with AC turned on

[Steveg203]

My 26 stumbles as well if you idle with the air conditioning on, not sure if this is a problem or if this is the way it is

Mine does an intermittent stumble while idling. I thought that was strange and I was ready to address this when I bring it in.

What's that sound that slowly climbs in pitch shortly after you begin driving? Hard to explain but funny and obviously normal.

The turbo?

Yeah, very high-pitch whine is probably the turbo (at least it does sound like that). I usually only hear it briefly as it spins up on acceleration, but I also have a high-pitch hearing loss so maybe it is blowing everyone else's ear drums ;-).

@Gumpus I think you are spot on, although one thing...4lo torque is after the transmission, so I would not expect that to affect a/c.

I checked with Google Gemini, and it does verify my suspicion that the a/c compressor uses an electric motor for the hybrid version, but a traditional mechanical pump for the gas models. So, that would explain differences as well as the sounds. Definitely one of the less-known advantages of the hybrid versions--I suspect there are quite a few that may not be obvious.
