I've recently noticed a weird sound coming from under the hood a few seconds after I turn off the ignition and get out of the car. At first I thought it was one of those muffled popping noises your car makes when it's hot, but it's a consistent sound. It drives fine, no problems or idiot lights. I've got a 2000 3.8 a4.. Anyone know what the hell this might be??

It's sound like your AC Condensor going on and off. Turn your AC off and listen for the sound.94 Quasar Blue Z28<br /><a href=\"http://www.9t4z28.com\" target=\"_blank\">http://www.9t4z28.com</a><br /><a href=\"http://www.9t4z28.com/Dyno1.htm\" target=\"_blank\">http://www.9t4z28.com/Dyno1.htm</a>

join the club...all 99+ have it...so that would include me :D Yes it's most likely the throttle blade closing. BTW, it's not the A/C stagen, that has it's own set of unique sound effects. [img]tongue.gif[/img]
