Hello! Have a problem with my Yaris for a few days. When starting cold (depending on the outside temperature) comes a quite agreeable flap from the engine compartment. When the idle speed is increased or shortly after the start it has disappeared. Now there are of course two possibilities: Either a component vibrates or there is serious engine damage. Has anyone ever had similar problems? For experiences, hints and advice I am grateful r. Since I’ve been driving Toyota, it would be the first serious problem – hopefully it’s really just an attachment. Greeting Christian
