Full Version: Hiss From Engine, After Releasing Off The Gas
Ford Owners Club - Ford Forums > Ford Models > Ford Focus Club

Is having a slight / short hiss after releasing off the gas normal in a 1.6 Zetec S ecoBoost?


I've only had this car for 8 days (From new, a 2013 plate), but I've only just noticed this as well.


It sounds like the noise that some people like to put on their car!

It's will be the factory waste gate for the turbo, mine does this also and so did my st previously before I had a big exhaust put on.

Ahhh makes sense. I still might get Ford to give it a check over though. It sometimes does it when I'm accelerating as well (I just noticed). Other threads on here suggested a loose pipe that pumps the turbo air, in to the engine?

Sounds like the waste gate nowt to worry about
If it was the turbo boost pipe ur would have lots of noise and lack of power.
