Val Demar Posted July 13, 2019 Share Posted July 13, 2019 So lately I'm hearing some kind of high-pitched sound when driving with windows down. Not very loud. This typically happens when the engine is cold, then it disappears. I discovered it is noticeable in neutral too. In this video the in first revving of the engine, this was like to 2.5k rpm, it is clearly audible when I let go off the throttle - you may need to crank the volume up a bit. In the second revving stupid birds add to the effect, but the sound is also there. Any ideas what it can be? Link to comment Share on other sites More sharing options...
fedaykin Posted July 17, 2019 Share Posted July 17, 2019 Hard to hear. Maybe pulley. Maybe belt slipping Link to comment Share on other sites More sharing options...

Val Demar Posted July 17, 2019 Author Share Posted July 17, 2019 (edited) There is a bird. But there is also a sound. It was the turbo heat shield vibrating according to my dealer, they managed to somehow adjust it, they had the car to address another issue in that area and they were able to find it while working on it. The sound was gone when I was picking up the car, hopefully that was it. Edited July 17, 2019 by Val Demar Link to comment Share on other sites More sharing options...
