Noticed this today: when standing still, there is a low frequency vibration (probably ≤ 40Hz) lasting about 2 seconds, then cycling through every 5-10 seconds thereafter. It seems to originate at a structurally-sensitive point that vibrates the frame of the car. Reminded me a bit of a sub-woofer in a car parked next to me.
On another forum it was speculated that this is the heat pump in action.
Any comments?
P.S: AC was off when this happened, so must be something else
