Boost Leak? (Fixed)
« on: 05 January 2013, 10:43 »
So the past few days when im driving, when I give it some gas I can hear this loud whirring sounds, the more gas I give the more it whirs,

I have a forge 008 dv fitted and this is now no longer 'dumping'

I am a total amateur when it come to cars but im off outside to have a look for anything obvious, but any help would be great.

Its a mk4 gti aum

Thanks

that said, its only started happening a few days after I had a full service (cam belt, waterpump) etc etc. that breather pipe has been on its way out for a while, and although I have noticed a slight loss in mpg, there is no loss in power.

the more I hear the noise, the less I think its a boost leak.

its like the whistling noise is coming from around the driver side of the engine towards the back/bottom.

the more I put my foot down the louder/faster it gets, if I ease off and drive at a steady speed, there is no whistle.

Check the pipe coming from the intercooler to the pancake pipe.  Its a common place for a boost leak and is located under the drivers wheel arch so would be around the area you are describing

What Rhyso said.  The push fit pipe is common to blow off.

Not had a chance to look yet but in my photo could someone give me the part number or name of the pipe that's split. It connects to the y pipe. Thanks
