Grown a pair of genitals?

Hi everyone for 11 years ive been driving and tinkering with MK2's, recently I got myself a mk4 GTI turbo (AUM I think) with 29k!  First thing I was looking at was a forge dump valve, but before I bought one my car started making it's own DV noise!

Kind of sounds like a group-B rally car when changing gears but I didn't add anything and it wasn't doing it before.  I can't feel any power loss when on boost but I can't help but wonder if something has come loose and releasing pressure when it's not supposed to be.  Can anyone advise, thanks.

Possible boost leak id say.

Have a look under the inlet manffold, there's a breather pipe prone to splitting, start the car and get some
One to rev, and have a hand/ ear all over the pipe work!

Fingers crossed it something simple

As above, probably a boost leak, also the DV's are pront to failing (the seal inside).  Smoke test would be a good option if you cant visually see anything

how do you do that then? park down wind to a bonfire? 

[monty9120]

mine makes a slight sound when changing gear. is this normal?

it mapped? you have a uprated DV?

lol, light a fire and funnel the smoke into your pipes!

some people make their own, but for the sake of £30 your local garage should be able to accomodate

TBH that sounds about right.  I do like this noise and when I fix it i will miss it 

I'll get a friend to help me later...

depends on how loud it is, even with just a panel filter you can sometimes hear it a little.

[Harooshum]

No it's not that loud but I doubt anything regarding air filter because it just started happening all of a sudden.  Like I said i do like it, but looks like it has to go!
