I wanted to let you guys know what's up since I've made several posts on different issues on my car. Hopefully this can be helpful to someone else. Maybe others can shine some light into this as well...
I had concerns on loud turbo (whistle) sounds when flooring it on 5th gear, above 3200 rpm on or about 80mph.
I had issues on creaking noises when shifting gears and gassing it quickly. Sound more prominent when it's cold.
I also was getting annoyed at the rattling A-pilar.
And, I thought I had issues with the throwout bearing. When in neutral and the clutch is disengaged, the engine is a bit louder VS. when the clutch is engaged, engine sounds quieter. It sounds like a very faint rattling sound when clutch is disengaged and in neutral.
Regarding the Turbo sound... Apparently it's normal. They tried to duplicate but they couldn't bc they can only get as far as 75mph. I showed them the video. They said at normal driving and at normal highway speeds up to 75mph all sounds fine and all is working well. Their explanation is, when you floor the car and it reaches a higher RPM at higher speeds, you are putting the turbo to work; more so than a regular conservative drive. Sounded like a valid explanation. Do you guys have any objection to that?... They did look at the hosings/ducts, they said they are all intact. They tried to tighten them some more but they were already tight.
The squeeky shifter noise... "FOUND SHIFTER MOUNT LOOSE CAUSING NOISE. REMOVE CENTER EXHAUST PIPE, REMOVE HEAT SHIELD, REMOVE HANGER BRAKET FROM TRANS. REMOVE PROPELLER SHAFT TIGHTEN BOLTS TO GEAR SHIFT / STAY TO TRANS. FROM CHASIS BUSHING SUPP. ROAD TEST TO VERIFY REPAIR." Arghhh!!! noise still there and it was louder! However, the sound seems to get lower and lower when car gets warmer and driven a good period of time. Maybe bc it's getting really cold now that more noise will appear? I guess that is another horrible noise to be added to the notorious sounds of the WRX. In a way I can deal with it as long as engine & tranny is good.
The A-pillars are no longer rattling! I'm excited over that... That was this morning. It came back at night. I'll have do it myself.
Throw out bearing... well they couldn't duplicate what I was talking about. They said if it was the throw out bearing, you would here something else. I tried showing them but they were saying that the engine noise of the WRX are traditionally loud. Hearing more engine noise when clutch is disengaged is normal. What they were hearing was normal.
They said engine wise is good. Tranny and bearing is good. I just find it hard to believe that a car especially new can make so much noise!
Anyways, if you guys think other wise let me know. Thanks again for all your responses and help. Hope this may help someone.
