Generation zero mullvadsberget tunnels key mission not in game

Cannot start mission . I have Base Game and both DLC’s finished all, cannot get this 1 mission to start, no note on car via You tube video via google. Took screenshot of stated car that note should be on to start the mission.

It unclear what mission you talk about. What is the name of the mission?

If it’s “The Ringfort” Mission, it pops up, when previous mission is completed. There is no item to start mission.
