      This randomly began on my way to work. It's extremely loud. Any idea what this may be? I took a short video of the sound. Thanks in advance.

      Failed water pump?

      Sounds like a vacuum leak small enough that it whistles. Does the car make boost? Any drive-ability problems? Any warnings from the cluster?

      Still makes boost. No drive problems and not a single warning light. Just this ridiculously loud noise.

      Or a bearing in a tensioner or the alternator or something.

      hope it's not the timing belt tensioner.
      Engineers do it better.

      But would I still be able to drive it normally with no indicator lights showing a problem and it drives a-ok?

      does the sound change when you increase throttle?

      you can eliminate/isolate the serpentine belt tensioner by using a 16mm open end wrench and pulling back on the tensioner. Remove the belt and see if you feel/hear any rough spots on the bearing as you spin the pulley.

      although i'm pretty sure that's not it, it won't hurt to eliminate it from the diagnosis.

      It's not happening as consistently as it was in the video I posted. I have to blip the throttle or roll the car forward/reverse to get the noise to happen now.

      Don't have a that size wrench on me. So it will have to wait.

      I'm gonna have to go with your first guess on this. Water pump. I can't back it up but that sound and reading posts in the past makes me want to say that it is the water pump. If so sorry to hear this. Look for blauparts timing belt kit with the thermostat ($280) included and find a buddy and get this service out of the way. Hoping you can do this yourself that is. Sure it's early but you'll have everything apart anyways, mine as well do it all. Good luck!

      It's going to the dealer (VW) tomorrow morning. If it's anywhere close to a grand, I may just trade it in.

      I'm afraid it might be. I would assume it is the same billable labor as the timing belt service which I believe is and 8 hour job (not really but that is what they will charge you). And then you have to factor in practicality as the timing belt will be accessed to get to the water pump. That is why I say go ahead and replace everything. Let's hope it's not the water pump first. ; )

      This is the guy I got:

      Welp, just got off the phone with AoA, never received it, but I have an open recall for the PCV valve and fuel pressure sensor. Thoughts?

      I claim not to be a tech at all but as much as I've been on these forums and as much work as I've done to my car I feel like it sometimes. I really doubt it would be your pcv with about 99% certainty. Those don't make that noise. If it was your pcv it would be more performance oriented. Like fuel cuts or the like. As if you had a air leak.

      See these two threads. This is exactly how my car is behaving:

      Did they mention a hiss as yours is??? Yours seems to not go away, just continuous.

      Got it to the dealer. The noise was not as pronounced as this morning and was intermittent. I did notice I now have a little back-fire burble noise coming from the exhaust and acceleration seems hindered a bit.

      Picked up the car after having the PCV valve and fuel pressure sensor replace (both recall) and drove it 10 or so miles back to work. No kettle whistle.

      I never said a thing to the dealer about the noise. I simply ask they perform the 2 outstanding recalls (PCV valve and fuel pressure sensor). I'm thinking the fix was the new PCV valve.
