    I thought I had a bad tensioner so I replaced both belts, both idler pullies, and the bottom tensioner, but still have this noise.

    can anyone tell me what this sounds like. I know you cant see anything but this was taken from just above the passenger side of the engine with the hood up. When I was doing the pulleys etc., when I had the belts off I started the car and the noise was not there.

    Thanks for any help. Oh, this is a 2010 jetta s auto with ~115K mi. Could this be water pump? No overheating and no leaks that I've seen. No major work on engine.
