engine noise

  1. Porsche Cayenne Generation 2 Discussion Forum
    Hi, I have a 2013 Cayenne GTS and noticed a knocking noise coming from the front of the engine bay when cold. Has anyone experienced this problem or knows what could be the problem? Here's a video in which the noise is very clear. Thanks https://youtube.com/shorts/elSRm01Ewis?feature=share
