Thanks @GrumpyGel then guess it's. Was in the garage with the container of the drained oil and he said it wouldn't smell like, just like burned oil, overdue for change. He also mentioned that they've never had that only with DPF cars or when the injectors are dying that it would leak back. He said to observe a bit further. Will check the oil level again and tomorrow drain it again properly down to minimum and see again what happens.
