The hissing sound means that the turbo is working ok :-)

Do you get boost? Does the car feel like it has more urge as the rpms progress upward?

The hissing sound may be the pressure waves from the air passing through the impeller vanes and into your intake.

The hissing sound should grow in intensity as it boosts the intake pressure. Back off the accelerator and the hissing will subside.

If the turbo was bad, it would not provide good boost, and you'd have bearing noise as well as blue somke coming from the tailpipe.....due to the bearing seals leaking.

If you do have a faulty turbo....upgrade it with a unit from these guys.

They can help you get better turbo response and less lag...
this means a more responsive engine and better mileage.

kindest regards

This reminds me of the days of the carburator. Blame something we don't understand. Could it be that the clamp that goes around the intake hose into the turbo is not tight enough, or it is leaking on the output side?
The turbo will not work well if it cannot inject that extra air/fuel into the engine because of leaks. (compare it to a ratty vacuum cleaner hose - same idea)
Bone up on it or take it to a mechanic(doesn't have to be a dealer - as many cars have turbos these days) to have a boo at it.

Well, its going to make a whirling noise and a hiss from the air intake, but the connection between the turbo and the intake maybe loose, and just needs a little tightening.

Turbos make noise when they are boosting and spooling...a hiss sound may indicate a leak at a flange...seek a pro to help you out because turbo repairs can be costly...

Learn from your Mistake and buy Another VW, but Not Turbo!

Thanks, RR

I am sure it's supposed to make that sound, considering it thrusts air into the engine. Same with my friend's car. he has the same one.

if it had a warranty on it, for days or miles, I would return to the dealer for repairs. if past warranty, aftermarket or factory warranty, then I would check to see if any recalls are out there to see if you can get it fixed for free. past that.....call up a mechanic, its time to throw some dough.
