Hey everyone, Just a fixing update; this particular sound was likely caused by a faulty PCV-valve / unit. I stumbled up on a video on youtube where the whining was similar to our car. That or some other video demonstrated that pulling the oil stick out when the sound is on makes the sound stop. I confirmed this with our car too, which pointed out to faulty PCV-valve / diaphragm. I ordered the whole valve unit part from Autodoc, which was about 40 euros in total incl. shipping, so I saved a decent buck while doing the job myself. Changing was surprisingly hard due to the stiff coil connectors and also the cylinders, but eventually managed to take everything out with help from screwdriver and tips from the internet. There's a good video on the change process here but the professional makes it look too easy lol:

In the video it chirps in "cycles" and is most notable at 0.05. Normally happens in throttle at low pressure / rpm. Also makes squeal noise when turning the engine off, if the problem is "on".

Hello guys, I've recently noticed that my Yeti 2012 1.8TSI DSG makes this whining / chirping noise. Noise is not present straight after ignition and usually begings after I've driven for about 30+ minutes on higher speeds. The noise seems to be linked to acceleration and appears in lower RPM's (1500-2500). Turning wheel doesn't seem to make a difference. I located the sound from the engine bay near the drive belt and got a new belt replaced at the shop, but that one didn't do the trick and noise reappeared. Could it be the alternator bearings etc.? Heres a video of the noise https://youtu.be/_zPKXrXA2xw Car is otherwise well maintained. Thank you,
