04 Audi Allroad 2.7T Whistling Sound, Please Help!
Hello everyone,
first time poster but I was wondering if anyone could tell me what is wrong with my 04 Audi Allroad 2.7T. it has 125,000miles on it, but recently it has started to make this strang 'whining/ whistling' sound on startup and when under load. It seems to be coming from the driver side underside of the engine, and someone had told me it may be the Turbo getting too much air. The exhaust does not smoke or anything, but it is just this strange sound. Is it the turbo seals, or is it just a hose that has come loose? I have attatched a video, if you could please take some moments to look at it, it would be greatly appreciated! I can include any other information, any help would be greatly appreciated. Thank you.

Whistling 2.7T Turbo
I have a 2005 2.7T Allroad that had what might be a similar whistling issue about a year ago. Most noticable on cold starts in garage. Could not figure it out for the longest time.
It ended up being a vacuum leak with the PCV spider hose assembly. Not too difficult to replace but takes some time with some frustration. While you have top of engine exposed suggest you get some vacuum line and replace all vacuum hoses because all were very brittle on mine.
