Whistle sound from GTI engine... Water Pump Failures

[Mk6 GTI]

lol - I'd suggest it is the turbo. My MKV is the second turbo I have owned and the turbo whistle is more pronounced than in the S15 I had. I find it most noticeable when slowing down (ie - pulling up to an intersection)

at idle also?

Nah not so much at idle. I don't think there's enough airflow through the exhaust headers to spool up the turbo at idle... (that statement is stretching my limits of engine understanding by the way)...

Hey Guys,

No the rattle is seperate.. I can definitely hear that!

I have never owned a turbo so im not sure. I noticed it when i parked in the garage and the car was at idle.. A whistle sound.. I hope its normal! :|

this could be the noise of the air inflow to your turbo, especially when u are driving at low speed, the engine is not at fully running, but the GTI's turbo actived at 1500prm, so the engine noise could not cover the noise of turbo, when you are driving in tunnel or beside the noise isolated wall, the feedback of air wave sound could be louder due to the limitation of the space to spread the engine(turbo) sound, so u can hear it louder than normal. in a narrow space u can always hear ur car's engine sound louder than a open space.
that's my guess, point out me if anything wrong.

LOL

Mk 6 GTI, u sure the car was idling and not turned off after a drive? I haven't noticed any whistling sound but when I turn off the ignition the fan stays on sometimes to cool the turbo

Ohh guys do u really think I'm that ignorant?? Seriously lol

yes the car was on, and yes I was in the garage while it was in park with the hand brake up lol do u hear the turbo whistle at idle isn't question?? Simple yes or no from some1 who has a mk6 gti. I'm just curious lol thanks

Yep, I have the same noise on my GTI and asked the service department about it. Apparently it's the camshaft actuator, and apparently the noise is a normal characteristic of the engine...
Cam.

I can confirm that whilst idling in a quiet space I can hear a very high pitch, like 14-18kHz, slightly oscillating noise coming from the engine. I'm sure the cars general quietness makes it worse. I have to stop noticing these things

[Mk6 GTI]

cool, thanks for your help guys!

Just another question.. if you have the stereo off can you really hear the turbo as you accelerate? Its loud with me.. dont particularly like the sound :| Sounds like an ford falcon LOL

[nau]

dont know how falcon sounds but yeh you can hear the turbo nice deep sound ....
ig you not sure thats normal go to the dealer and test drive what they have
