    Since it has gotten a bit cooler , I noticed that when I am parked I hear gurgling sounds coming from the dash area. sounds like bubbles coming to the surface in a pond or stream. I suspect that it is the heater circulating coolant but it sure is strange.

    Can you make a recording and post a link to it? I'd love to hear it! Sorry, though, never heard such a thing in mine.

    I have also noticed pronounced gurgling sounds in my 2012 Sig in recent months - it sounds like coolant moving through the system. Definitely a recent phenomena.

    Refrigerant most likely. AC compressor pressurizes the gas into a liquid which evaporates back into a gas in the evaporator. When doing short runs (common in "nice" weather) it may not run long enough to get everything fully running and you may hear some gurgling sounds.

    Turn the temperature down to a very low temp and see if the gurgling goes away after two-three minutes. If so, it should be ok.

    If its the one I hear, it sounds like coolant not refrigerant. Previously I had a a Durango that would blow out heater cores on a regular basis, every time it happened I would hear very similar sounds.

    I'm familiar with refrigerant equalization sounds. That's not what this sound is.

    It's pretty hard to hear. Probably easiest the last 5-10 seconds. You may have to hold your ear to the speaker.

    My new 70D makes exactly the same sound. Was wondering what the heck it is.

    Ditto here. Told my SC about it a while back, but it disappeared. Heard it again the other day for the first time in months.

    Curious indeed

    That does not sound like a liquid under pressure. It sounds like bubbles in a mud pit. I'd be curious too...

    There is no coolant in the dash, only AC refrigerant which doesn't make that noise. The heater is a PTC air heater.

    The coolant reservoir is just on the other side of the firewall though, and gurgling could mean there are bubbles in the coolant. Tesla has a vacuum device to bleed the system and remove all bubbles. If you are hearing gurgling, next time your car is in for service, have them vacuum bleed it.

    It'd be cool if we had turned on the "007" Easter egg, and this was an associated sound effect. But I'm pretty sure the sound isn't coming through my speakers.

    If it gets close I don't eat for a while. My cholesterol and lipid profile are looking great but none of my clothes fit anymore!

    My 85D makes the noise too when I'm stopped and the car is quiet (with the heat on). It's a faint noise, I'm not going to bother Service with the issue, I'm sure its nothing to worry about.

    It's actually a zen like experience.
    Relax your mind as you listen to the calming sound of the gurgling forest stream, brought to you by the good folks at Tesla Motors.
    I'm sure it's not harming anything. It's just a different noise and I wondered if I really heard it or if I was obtaining the skill of the zen master.
