Is my turbo dying?! - with video

[Gabriel2202]

I posted not to long ago for advice on a squeaky noise that only came on when the turbo kicked in, I thought I had solved it as the pancake pipe bracket was caught under the drive shaft making a squeaking noise.....

However, I've since taken it for a drive on the motorway and the noise I could hear inside the cabin is still there! It seems to definitely be turbo related and comes on at around 7 psi, and stays on through the rev range until i come off the accelerator. I don't have a boost leak so am worried that It may be a more serious turbo issue 

Here's a video (not my video) but it is the exact same noise that starts at around 11 seconds

Any help would be greatly appreciated!

Ah right, I didn't think of the vac lines, just assumed it would be boost  I'll check the brake booster lines tomorrow as it sounds like it is coming from directly behind drivers side dash that why i originally thought charge pipe connection.

Wouldn't my brakes feel heavier if it was a brake booster though? could a faulty n75 cause this?

sounds like a leprachaun stuck under there :-)

I had a noise like what you have in my last 1.8t it was my boost gauge swaped it and noise went

Ah right, was it the gauge itself? I'll take it off, stick a bolt in the end of the line and see if it goes then... so many things to check in this cold weather!

Sounds like a small boost leak to me, whistling indicating a small hole....
Is it just under boost, is it as you let off boost or at the end  before the DV blows off

It is just under boost, comes on at 7 psi and stops when i let off boost..... do you think a hole in the intercooler itself would make a noise like that?
