Iv'e heard the same sounds in the past in my car but it only happened when I turned on my A/C. I don't think it's anything bad just something to do with the A/C unit. It sounds wierd doesn't it. 
Sounds like when the coolant system was last fushed the didn't get all the air out. Reflush/fill the system. There is air trapped in the heater core is what it sounds like to me.SupraSC said:My friend owns a 95TT Automatic....When she steps on the accelerator, a loud water gushing sound comes from the dash.
It sounds like water is being sloshed around inside the car...
Her car runs perfect, no problems at all, but she is worried on what could be causing that sound. I checked her floormats and there is no water inside the car... The only other suggestion that I have is that it might be her heater core.
If anyone knows what this is please let me know!
Thanks,
Try parking the car on a slope nose up with rad cap removed (make sure the car is cold enough to remove the rad cap first of course). Start the engine and turn the heater on you should find that the air bubbles will circulate the system and be released at the now highest point in the system, the rad.SupraSC said:My friend owns a 95TT Automatic....When she steps on the accelerator, a loud water gushing sound comes from the dash.
