Hello guys, I’ve had a SL500 R231 BJ 2013 for 1.5 years with now 42000 kilometers on the speedometer. The car is checked and the last inspection was three months ago at Mercedes. I notice a noise when starting. https://youtu.be/afkf75mFtJU This noise never occurs when the engine is cold or when the engine is hot. The noise only occurs after the car has been driven and so it has stood for two to four hours, so it is still a bit warm. Ic h please for help, what can this be? Oil pump or control chain tensioner? Everything doesn’t sound good. Greetings from Stefan
