Hello. Colleagues, what could be the reason for such smoke when the engine is cold? When starting a cold engine, it produces smoke which disappears after a while and then. Additionally, you can hear strange knocking noises. The injectors were removed and checked and are in very good condition. The first video engine starting at -5 degrees and car standing overnight, the second video 8 degrees in garage and the car stood for several days. Later there is no smoke.
Thank you and best regards
