A pneumatic switching valve which is closed when the secondary air system is inactive thus preventing the flow of additional air is installed between the air pump and the discharge valve.
Leading evidence: 'Install between the air pump and the discharge valve' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Install between the air pump and the discharge valve' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Doing so should change the sound if it is the faulty part.

No way in hell I'd replace w/ new at those prices.

I think I have a good used spare if you're interested.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

This is a continuation of my saw noise, I am pretty sure I located where the noise is coming from. Does anyone know what part I am pointing to in the picture and if so, is it easy to change out?
Thats the bracket that holds that other thing it is connected too. I doubt it is yoru problem.... Sorry I couldnt resist. it IS, Oh wait thats Tomorrow..... ST Patty's Day/
Stand by I am looking at PET
I gave ti the ol collage try and I cant find it in PET
There's some sort of electric fan in there which acts as a blower. Not sure exactly what this does for the engine, but it must be somewhat important! I think I have a good used spare if you're interested.
BTW, this is VERY easy to change out. It's just bolted in place and the hose just pulls on and off.
Is that the part making the noise? If you aren't sure you might be able to tell if it is by applying pressure on it when the whining starts. Doing so should change the sound if it is the faulty part.
Yes It makes noise on start up. I can hear it from there and then when car is done warming it stops making the noise. I also can feel it vibrating the whole time the noise is occuring and then it stops once the noise is gone
The Air Pump is used to reduce pollutants contained in the exhaust gas during the warm-up phase and to achieve the emission limits of the roll test in the USA, USA vehicles have a secondary air system. For this reason, an electric air pump has been mounted on the left-hand side of the engine compartment (Carrera). This pump is activated by the DME control unit and blows the additional air through air ducts to the discharge valve. A pneumatic switching valve which is closed when the secondary air system is inactive thus preventing the flow of additional air is installed between the air pump and the discharge valve.
Functioning
If the engine is started in a temperature range between minus 10.5� C and plus 45� C, the secondary air system is activated for a period of time dependent on the start temperature (min. 50 seconds, max. 179 seconds).
The secondary air system is only activated if the following engine-related operating conditions apply:
- Engine load (TL) between 0.7 ms/rev, and 4.7 ms/rev.
- Air mass (ML) not greater than 300 kg/h
- Engine speed between 680 rpm and 2,800 rpm
- Altitude adaptation factor greater than 0.76 corresponding to less than 2,400 meters above sea level."
Other than being a noisy pump it will not hurt anything. But, if you’re anything like me the noise would irritate the hell out of me. And, if it were me, I would start looking for a used one. They are not a high failure item. Save you a ton of cash! GL
+1 to that.
The whining doesn't bother me that much since it doesn't last long, and isn't that loud in my case. I will listen for changes in the noise and decide on replacement then.
No way in hell I'd replace w/ new at those prices.
Parts Heaven in CA should have these used too. I use DC since it's East Coast.
On my audis i used to rip the secondary airpump out and throw it in the garbage....I have the same wierd noise....from the back on occasion...Im not worried...when i breaks Ill sell it to ed too.
$1500 bucks. That's unreal! It's a little electric motor with a plastic body. Does it have a computerized output or something?? Very easy to change out BTW.
This is a source reference. Confirm exact model applicability in the original material.
