If it is the expansion valve, I wonder if it can be replaced easily to alleviate the problem.

I've got an '02 Targa, and during the high summer heat in L.A., tend to use the A/C a bit.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

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.

9 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Just to preface this, I've been doing a search for the past 45 min on this issue and haven't found anything related (maybe it's not really a problem and is normal - or my search skills need some tunin'). I've got an '02 Targa, and during the high summer heat in L.A., tend to use the A/C a bit. It blows crispy cold and works great overall, but upon shutting down the engine after the A/C's been on, I get a loud high-pitched whine that emanates from what seems to be the central and right-sided parts of the dashboard and from above the glovebox. This lasts for about 5-10 seconds, and subsides spontaneously. The noise does not occur when the A/C has not been running. Anybody else experience this? Seems like such an unsexy sound for the sexy beast that she is.

POST 2Original post

My '01 Boxster made a similar noise. In 5 years of ownership, the AC always worked wih no problems. So I just assumed it was "normal." My '03 C4S does not make that sound.

POST 3Original post

Mine does make that sound after running the air once in a while - like the vents are re-setting or something. Mine is not loud though, can just barely hear it.

POST 5Original post

Are you saying that I put an abnormal brain into a seven and a half foot long, fifty-four inch wide GORILLA?

POST 6Original post

Ah, good call. They normally make that "water traveling through a pipe sound", or when your toilet is almost full of water and the valve is slowly closing off the water.

POST 7 / ORIGINAL POSTEROriginal post

Thanks for the input, guys. Somewhat comforting to know I'm not the only one... but probably the one with the LOUDEST sound. If it is the expansion valve, I wonder if it can be replaced easily to alleviate the problem.

POST 8Original post

probaly run you about 100-150$ in parts and 2-3 hours at a shop

POST 9Original post

I know this is an old thread...but did anybody figure this out? I get the same noise.... Doesn't happen everytime, but I don't really enjoy hearing my P-car moan after a shutdown .
