So, today I noticed a quite loud whistle/hooty sound. I've not investigated it yet, but I'm sure it's turbo related, or a vac hose issue.
I am due to strip the turbo down very soon as it does go into limp mode if I boot it hard.
Am I right in my initial thoughts?
Here's a link to a video of said noise.
