When I replaced the alternator, I used the Bosch one since it had a clutch, and the Napa one didn't.

I had a very similar sound to this until my mechanic found a loose spark plug and tightened it (actually he just replaced it).

I'm tempted to replace the starter while I replace the SAI vacuum lines next week.

Suggestion
If you use a shop, then most likely replacing it with a new one $100+ (Bosh new) will be less risky since you never know if the lube will bring it back.
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.

Hey guys,
I've got a 2002 Targa with 80k miles on it. Just started making a squealing noise for a second after starting the engine when cold (morning or afternoon). Does not make the same sound when the engine is hot. I took a video with my phone but you can't hear it very well, but then I found the video below on YouTube. My sound is similar but not quite as bad.
Something with the starter motor? It's also been very humid here this week, maybe something with the belts? If it's the starter motor, would that be an easy DIY?
Thanks,
Chris

Doesn't sound like a belt as I imagined it to be. Sound more like the starter not returning fast enough after turning the engine. Does sit sound like that if you don't rev immediately after it fires up? Keep your foot of the gas and fire it up.
Rev climb then drop after start is normal.
I agree with Hurdigurdiman regarding the sound. Sounds like the starter isn't returning fast enough or the clutch on the starter motor gear is if not going bad is noisy and likely to go bad. Obviously if it is the starter motor pinion gear clutch it shouldn't make any noise and when they do it is not a good sign.
I get the exact same noise. Happens intermittently, seemingly no pattern for me. I can have a weekend where is does it 2/3 of the time, then not have the sound for 2+ weeks straight.
I had a very similar sound to this until my mechanic found a loose spark plug and tightened it (actually he just replaced it). The sound was a blast of air coming from the cylinder through the threads. The reason for the sound was located in part due to advice from someone on Rennlist. Check it for yourself and why not - will not take you long to eliminate if this is indeed the problem.
Startup squeal has gone away for now. Was quite humid here in SoCal last week, read somewhere that the belts can make this noise when it's humid outside. Hopefully that's just it for now...
Nope, that a classic the starter over run. My VW had it for years, sounds bad and can be embarrising but it won't hurt anything. The bendix (the gear that jumps in and out) needs to be greased up, that's all. Usually does this in colder weather.
I have a similar issue. Would love to know how this turned out. I am tempted to just replace the starter and see if the noise goes away. Mine also starts sluggish a few times and then die when I hit the gas. Restart and fine. Always after sitting more than 8 hours.
Yes, if you DIY and don't mind the labor, you can remove the gears and lube them and that should fix the problem.
If you use a shop, then most likely replacing it with a new one $100+ (Bosh new) will be less risky since you never know if the lube will bring it back.

Earlier this year my Boxster was making a similar noise -- maybe not quite as severe maybe though I never listened to the noise from outside the car -- upon cold starts. Tech diagnosed it as a dragging overrun clutch. The noise could be exacerbated by a slow to disengage pinion gear too.
But the noise has gone away and I can't recall the last time I heard it. But it is a bit warmer now than it was earlier this year when the noise was present so I'm thinking it is a colder weather problem, though at some point the thing will degrade to where it makes the noise even in warmer weather.
Oh, and the tech said the starter can be "rebuilt" when the time comes vs. replaced.
Any reason I should pay more for the Bosch starter, or is the Napa one fine?
When I replaced the alternator, I used the Bosch one since it had a clutch, and the Napa one didn't.
I had the same noise on startup about 33% of the time. Replaced the started bc I was embarrassed when starting it up at AutoX and everyone would look at me like "wtf was that noise?"
