Reported cause
I remember trouble shooting a squeaking noise on two different cars in the past that turned out to be unevenly worn brake pads.

I�ve inspected the brakes, the wheels and tires, the under carriage and I can�t see anything that pops out at me.

The car only has 25k miles on it (I put 4k of that on it in the last two months) and that�s what it looks like everywhere I�ve inspected: like a 2-year-old car with the appropriate miles for that age (even though it�s almost 15 years old).

Luckily the only time I�ve ever had an animal under my car they�ve ran when I started it.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Since I have found nothing else on the internet about this, I decided to start a thread in case anyone else has this problem.
I have a squeaking/squealing coming from the right side of the car. I know it�s coming from that side because I can barely hear it on the other side. I think it�s coming from the rear, but I can�t really tell. The only time I can hear the sound is when the car is in motion. It starts kind of chirping at 20-25mph, then by 30-35mph it�s at its full frequency and volume. It�s a constant high pitched squeaking with the cadence of an engine turning over but not starting.
The sound is not affected by: the clutch being depressed or not, engine speed, gear (any gear, in or out of gear), brake pedal, ebrake, windows up or down, spoiler up or down, vehicle speed (once above 30mph), turning, or anything else I could think of to try. It is intermittent as well. In fact, while I was trying to get a sound recording of it yesterday, it kept stopping. But it came back and I got a few recordings of it (I don�t know how to post a sound clip on here though).
I�ve inspected the brakes, the wheels and tires, the under carriage and I can�t see anything that pops out at me. The car only has 25k miles on it (I put 4k of that on it in the last two months) and that�s what it looks like everywhere I�ve inspected: like a 2-year-old car with the appropriate miles for that age (even though it�s almost 15 years old).
What could this noise possibly be? Are there any areas on this car known to catch debris, like leaves or something, and cause a whistle that sounds like squeaking?
Make sure the disc brake backing plate is not loose or rubbing on the disc, also might have to pull the disc off to make sure there isn't a rock or debris in between the backing plate and disc. After jacking it up, before removing the wheel, rock that wheel top and bottom, and side to side to see if the bearing has any play.
The above is what happened to me, so that is a real possibility. What about the wheel bearings? Is there an easy way to check to see if these are going bad?
It definitely doesn�t sound like a wheel bearing. I removed the right rear wheel and rotor yesterday and inspected it then adjusted the parking brake adjustment screw and there was no change. I just drove it again and now I think it might be in the front, so I�ll take that wheel and rotor off today and see if I find anything there. I heard the noise at well under 20mph, so I�m almost certain now that it�s something rotational.
Thank you for the replies! Hopefully it�s just a pebble stuck in the dust shield.
Do you have a clear bra? Could be film starting to peel up and creating a frequency with the wind. I had film on my mirrors and got a high-pitched, whistling-like noise when it started lifting.
Since the engine rpm doesn't affect the sound, and you are confident it comes from one side versus the other, it has to be related to moving components on that side. There isn't much that it could be other than wheel/brake/suspension interaction. I remember trouble shooting a squeaking noise on two different cars in the past that turned out to be unevenly worn brake pads. The pad on one side of the rotor looked fine, but the other was worn down to the rivets (in the case of these old style pads). The noise was intermittent at first, especially when the car was turning. In both cases, the root cause was that a caliper piston was sticking on one side. Your car has been sitting a lot, based on the low mileage, so that would be a possibility.
I don�t have any PPF. There are no uneven pads or anything one can see with a visual inspection of the wheels/brakes/suspension. I have trouble believing it�s a loose spark plug, or anything engine related for that matter, because it doesn�t change with engine speed.
It
could
be a sound caused by wind; it is not necessarily something rubbing. It doesn�t make any sense that it would stop making any noise under 20mph if it was caused by rotational friction from forward motion. The times that it has made noise under 20mph have been windy, which was something I didn�t consider while it was happening so I didn�t take note of the direction from which the wind was blowing at that/those moment(s). If it was something in the brakes/wheels/suspension it would do it at any speed and I would be able to recreate some kind of similar noise when I manually spin the wheels with them off of the ground. It seems like it needs at least some air movement for it to happen, so I can�t rule out wind noise. If it was in the brakes, the noise should change when I press the brake pedal - it doesn�t.
NOTHING
changes the sound other than slowing down to under 20mph; I cannot emphasize that enough. Anything one would try to troubleshoot this sound on any car, I have done. But I�ve never had to troubleshoot anything on any Porsche.
I wish I had a lift so I could just take the whole damn thing apart. With a lift, I could�ve had this problem solved in a couple hours at most.
This is kinda funny - yesterday I drove to Walmart to get some stuff and listen to this noise. When I got home, it was 80� in my apartment (there are large windows all the way around it and, even with the blinds closed, the sun heats up the place), so I turned on the AC. I�m sitting on the couch and I start hearing the same noise my car is making! I say out loud, �is it following me?!� The noise was coming from a closed vent in the hallway bathroom. So I�m certain now that sound can be caused by wind. I�m not certain it�s wind noise on the car, mind you. But I can�t rule out wind noise.
You need somebody to drive the car, so you can sit shotgun with the window down and listen outside the car. That should at least get the region figured out. Those high pitched noises can be a real PITA, they sound like they are coming from EVERYWHERE, Another thing to try is to pop the frunk, so it's on the secondary latch. If it's something whistling by a gap there just opening it that much will usually eliminate a noise. Obviously, don't drive it far like that.
Wind noise around the door window gasket? It is very common for them to get hard, shrink, and make noise. There are several threads on this forum about the issue.
You are making it tough on us by not providing the sound!
It�s virtually impossible to get the sound on recording. The only recording device I have is my iPhone and it picks up all the sounds other than the one I�m trying to record
very
well. So I have video with the sound, but one can just barely hear it over all the other driving noises. It�s extremely frustrating. I drove to Home Depot this morning to get bunjie cords so I can take the front caliper off today. It didn�t make the sound until I was almost back home, but I�m pretty sure now that it�s at the front passenger side and it�s not wind related. Hopefully I find it when I get the rotor off.
I was getting the same loud squealing sound. Drove about 10 miles, pulled into a parking lot, and the sound was still happening even with the car parked and turned off. Look under the car and my cat was snuggled up in there. Guess to keep warm? Crazy animal! Bet it freaked out driving down the road. Heck, I about had heart failure too when I first heard it.
There�s a cat that my mom has been feeding in her neighborhood and while I was there the cat and I bonded (she walked on my car once, which I wasn�t too happy about, but she only did it the one time out of curiosity I suppose). I am terrified of the possibility that I�ll go to leave from my mom�s house and the cat will be under a wheel or something. I would be horrified if I found a cat, even if it wasn�t mine, anywhere in my car.
I removed the caliper and rotor, inspected, and reinstalled everything. I didn�t see anything at all that looked even slightly off. Everything on this car looks exactly the way it should. I went out for a test drive and the sound is gone.
My only guess is that there was something in between one of the pads and their guide rails (whatever those things are called). I wiped all the surfaces and blew the brake dust out of everything I could, but I seriously doubt that�s what fixed the problem. It also could�ve been the piston(s) sticking, as was mentioned in an earlier post by Splitting Atoms, and compressing the pistons to get the caliper off of the rotor may have unstuck it/them.
Kind of anticlimactic. I wish I knew exactly what it was, but at least there was a fix. Removing and a cursory cleaning of the caliper and rotor seem to have resolved the issue. I�ll update the thread if the sound comes back.
I had a rabbit nestle in behind the wheel of my moving truck parked on dirt...It was sad as my partner called me a few minutes later to tell me what he found. I turned around and rushed it to the Humane society but it was to far gone to save.
With that said, most will run once you start the car.
Lost my cat as a child when my dad started the big V* and the cat was sleeping in the engine bay though.
Luckily the only time I�ve ever had an animal under my car they�ve ran when I started it.
The sound came back today. I took it out to just drive it and after a few spirited corners, it started squeaking again. I�m sure it�s on the right front wheel now and it�s probably nothing more serious than a build up of brake dust getting caught around the pads or something like that. I�ll report back if I find anything new.
