My 04 WRX has about 3k miles on it, and I did notice many, many weird sounds from the car, but I did learn about most of the usual WRX quirks from nasioc and i-club.
I have a few things that i'm worried about.. one is that the A/C compressor makes a low-pitched whining sound when it's engaged at idle. The sound comes and goes .. you can hear the a/c compressor click on, and it'll be all like "brrrrrrrrp............brrp....brrrrrrrrrrrrrrrrp" .. the sound will disappear when the a/c compessor stops/ clicks off and will come back when it engages again; what, maybe a bad bearing inside thats making all the noise? (kinda sounds like a bicycle's brakes buzzing/ squealing when the rubber pads don't grip well) I can also hear a single "tick" sound outside the car after I release the clutch pedal from a fully depressed position, at idle. It happens every single time, but I need to hold the pedal all the way down for a half-second or so. If I don't hold it down for a bit, it doesn't make the sound. Also, i've experienced the famous "deceleration noise" in 2nd gear when letting the car engine brake/coast down on its own, but .. I noticed that it's pretty f*ckin loud, not to mention that there sounds like something in the transmission is rattling like hell in there in additon to the gear whine. Sounds like a jet engine slowing down when i'm decelerating. Only happens in 2nd gear. Is this alright?
Lastly, I have a potentially serious problem as i've read tonight while reading up on clutch adjustments, and apparently a pulsation or vibration of the clutch pedal is not supposed to be normal?! I can feel the pedal vibrate/pulsate when I press te clutch pedal in just slightly, about an inch or two. It's been like this since I got the car. When its fully depressed, or its around the bottom section of it's travel, there is no vibration or pulsation. From what i've read, its not good. Here is some of the stuff I found.. Not sure if it applies to boxer engines in general but I assume it does since the transmission / clutch design is pretty much the same.
"• Pedal Pulsation — If the clutch pedal pulsates or vibrates when depressed, it usually indicates misalignment between the engine and transaxle or an internal clutch problem, such as a broken clutch diaphragm spring, a warped or misaligned pressure plate, or a warped or bent clutch disc. "
from http://www.artsautomotive.com/clutchstory.htm
"Clutch Pedal Pulsation Movement felt on the clutch pedal or operating lever when the clutch is being disengaged is called clutch pedal pulsation. These pulsations are noticeable when a slight pressure is applied to the clutch pedal. This is an indication of trouble that could result in serious damage if not immediately corrected Several conditions could cause these pulsations. One is misalignment of the engine and transmission. If the engine and transmission are not in line, detach the transmission and remove the clutch assembly. Check the clutch housing alignment with the engine and crankshaft. At the same time, check the flywheel for wobble. A bent crankshaft flange or an improperly seated flywheel produces clutch pedal pulsations. After the flywheel is properly seated, check it using a dial indicator. If the crankshaft flange is bent, the crankshaft must be remachined or replaced. Other causes of clutch pedal pulsations include uneven release lever adjustments, warped pressure plate, or a warped clutch disk. If the clutch disk or pressure plate is warped, it should be replaced. It would be impractical to list every possible clutch problem and its remedy for repair in this training manual. Table 7-1 lists other possible clutch problems and their corrective action. Consult the manufacturer’s operation and repair manual before making adjustments to any clutch system."

Of course its still under warrenty, havent done much to it, disabled the drl, took out the silencer and cleared out the headlights.. lol they shouldn't bother me about it right? I haven't taken it in for service before .. Does anyone know if this stuff is normal or should I make an appointment at the dealer to get it checked asap?
Sorry this post is too frickken long. I feel like i'm pessimist... hey.. when you have a car you love, when something seems wrong, it annoys the hell out of you.. or maybe i'm just a crazy stupid idiot. Thanks for the help anyone. I REALLY appreciate it. :cool:
