Weird bubbling sound coming from behind gauge cluster?
Hi all
ive noticed this sound before when im idle sitting in traffic. it sounds like a coffee pot when the water is pouring down or a bubbling wet sound. No idea what it could be. Seems to come from behind the gauges
Any ideas?

Actually.....
It's your master cylinder and or the fuel pump doing its job, you'll hear it when you first start up in the morning......do this when you first start your GS, just turn on the ignition but don't start the car. You'll hear it go thru its motion, it's the same sound when you're just idleing. Hopefully someone else can chime in, but I'm pretty sure that that is what it is. Let me know how it turns out.

And your cooling system makes this bubbling noise? Then you my friend have problems and don't know about it. I don't have bubbling sound when I turn my A/C unit on, hell I work in HVAC and I do know what to listen for. The noise is not bubbling and like the previous post says it's hard to describe. It's like a relay sending the unit a signal to run it's functional test, then you hear like a motor running, then you hear it turn off......that is what I was referring to. Hope that makes sense.....

well when I take off from a stop I sometimes hear a gurgling or bubbling noise from behind the gauges.
Does not do it all the time, my temps are fine, no leaks, I will try and bleed the system, but it's only from a stop not during idle. does sound like it's from the heater core running through the hoses along the firewall

My GS has just started to do this every now and then. My ES used to do the same thing but much more often. I looked up a fix for it, on the ES forums, which was as simple as going to Lexus and have them purge the air in the heater core. Several people have done this with great success and only being set back $15.

Purging the air from the heat exchanger??? Sounds like magic.. and for 15 dollars they can't do much.
Is this noise that you hear only happen when you have the heat on? I am pretty sure that there is a temperature valve that regulates the amount of water flow thru the core.
I would suspect a sensor malfunction and look really had at the ABS unit.
Maybe the brake ECU thinks the car is moving and the wheels are stopped. That would make the brake ECU activate.
This is just my two cents. I am interested in what someone finds out here.
