Noise when depress throttle
I have a strange noise occurring when I depress the throttle after accelerating. It sounds like a cshhhh with a slight undertone of metal rattling?
I am guessing my throttle body may need a cleaning, any suggestions?

my suggestion would be to give information about which car you have when you post- year, engine, transmission, quattro/fronttrack. theres nothing more irritating then people asking questions without giving the information required to answer them.
i can tell you with a good amount of certainty that it is not your throttle body as it would not make that noise.

But we will play along... what are the details on the car?

My car makes a similar sound. I have 183K and I have narrowed it down to something rattling in my driver side catalytic convertor. Put your car up on a lift and have someone depress the accelorator and see if the noises come from the cat. It could either be internal damage to the cat in which case you have to replace the cat or live with it as I am doing. You could also remove the bottom screen off the cat and see if there are rocks stuck in there causing the noise. Welcome aboard and good luck

No this only started to occur recently, it is definitely not the turbo spool. My guess was the throttle body (the valve is it called?) may be rattling and producing the noise.
I am being serious, the noise is really hard to describe - I will need to provide a sound byte when I find a sensitive microphone.

Rattling metal might be the exhaust manifold, or something else said above, I wouldnt worry about it. Woosh sound sounds like a wastegate/diverter valve... but you cant usually hear the stock one, so kind of strange, the valve is located under the car near the very front passenger side of the car, it has two equal size hoses running to it (maybe a little over an inch in diameter), and another very small vacum line, it looks like little black canister that you could hold in the palm of your hand. The only reasons why I think you would hear it was if it were replaced with a non stock one, you have a non stock intake, or you have an intake leak somewhere. The acutal noise from a turbo is a high pitch whine.. I guess you posted at a bad time, happened to be when the ******** were on I guess, your question wasnt that bad, people post about simpler issues that can be found in their owners manual all the time.
