A common problem with the GTI's - this thing that looks like a snail attached to the exhaust tends to make such sounds...

Is it the turbo perhaps your hearing?

Are You talking about this one?

Different descriptions ... probably same noise ... If You look through that thread You can find some answers as well as recording of that noise.

Haha, this is funny, that noise is the Turbo.....

Means its a good noise not a bad noise.

No, there's definately a problem. You should just give that GTI to me right now so I don't have to wait any longer.

lol - yeah - that's probably the turbo you're hearing! If it's not the turbo, then it's the wastegate rod as per the thread that MIRSAD mentioned, and then I can merge this thread into that one

EDIT: Actually, I noticed the OP already posted in the rattle thread, two minutes before posting here.... so which is it man?

I doubt he is talking about that, a whistle and a rattle are to 2 distinctly different noises.. The turbo on my Mk5 GTI is quiet loud and its just standard, its audiable with the windows down or if your driving next to a cement wall/ tunnel.. I was surprised by this as i had driven a few other 2.0tsfi (in an audi A3) and there was no turbo sounds.. Is this normal? even my g.f noticed the noise one night..

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! :|

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)

[MkVIGTI]

Do you have a kettle in your car by any chance?

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

at idle also?

[Axis]

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)...

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.

had a TD prado once, my wife thought she could hear a siren everytime she drove it ....lol!
