Mine sort of does that too when starting cold. When I still have the clutch pushed in after starting its fine, but when I release it in neutral, I hear the scraping and definate difference in the sound of the engine. Could this be a problem with the clutch?

MY00 RS, 25k miles.

Unhappy Scratching/Scraping sound when cold starting

As soon as the car motor engages, right after I turn the key, and when its cold. (left for about 8 hours). The engine does a quick little SCRATCH sound. Like something is scraping against something else. Metal to metal. Has this happened to anyone else? And if so, what was done about it. I'd like to know before I have to leave it overnight at the dealer.

BTW, 2K RS with 27000kms on it, it's been happening since just this winter.

Geez, it seems its not common, = bad news!

its not after I let go of the clutch, its just after the key is turned for a split-second but very noticeable. Guess I'm gonna have to bring it in... thanks guys.

Mine makes a weird noise when I start it up after it's been sitting for a while. But, after that it's fine.

Hello. I am new to the forum. I am resurrecting this thread because I have a similar problem to my Impreza. It is a newly bought 2010 model with only 500 miles on it. And no after-factory undercoat job is performed.

To reproduce the problem, I park the car overnight, then start the car. When I accelerate (gentally not hard), there is a scratching noise from the bottom underneath the rear right passenger seat area. The noise is soft but is still noticeable, and it lasts momentarily (for about 0.1 second). After that, the car will start normally without the noise for the rest of the day. And it is reproducible every day I start my car first time.

I left my car overnight at the dealership for testing but the technician claimed he could not hear it even though I test drove it with him and heard it myself. So I have no choice but to leave without solution.

Does anyone know what this noise is? It is not a loud noise but I doubt it is normal for a brand new car. Should I wait for it to wear off?

when you turn your car on do you just go straight to cranking it over or do you give it time for the fuel pump to prim and then crank? I would turn the car to the on position without cranking it wait till you hear the fuel pump finish then start the car and see if you hear the same sound.

Forward/backward does not matter. And the noise happens when I apply gas.

I have a similar sound on my 03wrx, after start up for a second or two I get a sound like a starter holding but its a highr pitch sound. I know the starter holding sound and this is not quite the same.
I usually let my walbro pump prime a couple times before I start it.

Mine does the same thing from an overnight cold start after rolling forwards about 15-20ft. I have 10k miles on mine and no prob at all. Dare I say "they all do that." But I wouldn't worry about it
