Title: Boost Leak? (Fixed)
Post by: stfc_gti 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

I remember my mate telling me about this, he bodged it for me but said I needed to get it replaced. he said something about a breather pipe?

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

If i was keeping her i would do this, but typical luck, just as i plan on getting her ready to sell, everything starts going wrong. :sad:

It would seem one of the jubilie clips had come away from a pipe causing a boost leak. All sorted now and she is back to normal.

I dont want to sell her now.  :cry:

Mainly because im doing anywehere between 60-100 miles a day commute now and time has come to get something a bit more economical. I've been doing it for the best part of a year and im putting so much petrol in her its not even funny anymore.
