Moin, I just came home and let the car run a little before I put it off. Then I smell –> exhaust gas in the interior. In front of the headlights slowly and greyishly –> exhaust gas. Armed with a flashlight and mobile phone camera, I open the hood and look for where the stuff comes from. Unfortunately, I couldn’t exactly locate it. It’s not surprising, however, that it came up from behind the engine. In addition to the tackering, there’s also a periodic sound to be heard, like a situation r(?). (-> Videos) While I’m still standing there, I suddenly hear a mechanical noise, some planned control (?) and also the engine noise change slightly. The periodic noise and smoking stop. I don’t watch this for the first time, but I finally got it recorded. What about the cuckoo can that be? If this was a crack in the exhaust manifold, then it would always have to be. If there are exhaust gases from under the car/particle filter up into the engine compartment?
