You can definitely get enough clearance with a standard car jack to take a look at least. You will probably have to remove the plastic undertray to be able to see up there though. It's pretty easy, there's 7 torx screws to detatch the undertray.Last edited by Primordial; 09-12-2015, 10:33 PM.

Hi Jon
Thanks for the video. To me the sound when you tapped the heat shroud is much closer to what I'm hearing - it has that sort of resonance where the sound lingers slightly rather than the scratchiness of the heat shroud.
Is there anything around the heat shroud it that might come into contact with it?

I would be extremely surprised if it was the upper heat shroud causing the noise (unless you're hearing a different noise?). It's almost certainly the mesh cage vibrating, in person it sounds identical to the rattle I was hearing. What you have to remember is that the mesh cage is vibrating at 40hz roughly (2500rpm/60 secs). It's going to sound like a 'lingering sound' as the revs increase and the cage moves out of its resonant frequency.

^ I've done 5k km and its as bad as ever (irrespective if cold/heat) so unlikely to change.
I'm currently considering a package to "remedy" the situation: Intercooler, CTS Down Pipe and a JB1 tune (Stage2). (as a side Primordial, can you give us a review of how you are finding your Stage 2 set-up?).
its a fair sized $ investment but has the advantage of a tidy performance gain, richer/deeper sound and no more rattle! Its either do that, spend the coin or sell the Wolfie as its currently that bad that I've almost go no choice

I've been reading some forums on the Audi S3 which has a similar issue apparently.
One of the comments linked to a video of a guy explaining how a turbo operates. Every time he opens the wastegate it makes a metallic noise and a lot of people on the forum think this is the issue with the wastegate fluttering as gas exits.
If it is this then it echoes what my dealer said about it relating to the turbo and being 'normal' (i.e. too expensive to fix)

On the MK7 the issue definitely has to do with the downpipe, that's a fact. Changing the downpipe does fix the issue. I'm 90% certain it's the cage around the flex joint vibrating on the standard downpipe.
Does anyone want to get up under theirs and see if they can get to the flex joint? If so, it might be an easy fix by just wrapping the flex joint with some exhaust wrap.

Hi all,
We have a 6 month old GTI PP with the same issue.
It started at about 300km on the clock and now has 6000km.
Have taken it to two VW dealers and test drove the vehicle with the tech inside.
Both times they stated they could not hear anything. Then after pointing the sound out they agree its there.
They advise that this is normal and that its the turbo spooling up. No idea if this is the case or not.
But its really annoying. Sometimes its louder and other times quieter.
So I have the music on minimal to mask the sound. It has really put a sour taste in ones mouth but what can one do????MK7.5 Wolfsburg.....

Not much unfortunately Pete. I would be making a small fuss about it whenever you put the car in for service. The more people complaining about it, the more likely they are to come up with a fix.
Given where the sound is coming from though, I don't think it's going to be a simple fix. VW are more likely to just keep fobbing it off as a 'feature' of the engine.

100% the sound is gone, not even a hint of the sound since installing the downpipe. That is a definite fix.
If you dont want to replace your DP, you can see if an exhaust shop can wrap the flex joint with heatproof exhaust wrap. This will reduce (or stop entirely) the vibrating sound, as the metal cage around the flex joint wont be able to vibrate. Shouldn't cost you much more than $100.
Alternatively you can wait for VW to come up with a fix, but I seriously doubt they will fix this, given the fact that they'd have to redesign & replace or at least modify the downpipe to remove the cage or something. Neither of these options are a simple fix - it's highly unlikely that they will outlay that much investment for a 'small rattle' (in their opinion).
