Moin, has been having a problem with my e81 for 3 months. He does quite normal when he’s cold, when he’s warm (about 95°) then he drives normally, but as soon as I shut down the engine, it doesn’t turn on anymore, cranks can be heard (video: https://www.youtube.com/watch?v=7y1-kyYEoWw), but the engine just doesn’t want to start. The thing is the car drives perfectly even if the engine is hot, just when I shut it off the theater starts. After about 15 minutes runs away I have already changed: -Zündkerzen & Zündspulen -Nockenwellensensor -Kurbelwellensensor -Luftmassmesser -Lambdasonden vorm Kat -Noxsensor -Fuel pump (low pressure) I also removed and tested the injectors and also cleaned for safe maintenance-> do not drop fuel pressure is present and according to ISTA in the green area codes there is no (more, had before several codes concerning nox sensor and lambasonde n, but have they since the change not at all) suspect maybe any relays, temperature sensors or ECU? Or a combination of it. Do not know me with the electrics really well. I have already brought car to BMW, which meant they don’t want to try and test until the control chain is changed
