If you are a modern player, yes—Steam will auto-install this update, and it is now the baseline for all recent patches (up to the current 2.3.004 and beyond).
However, if you are a retro-modder preserving a specific 2017 mod setup, this update is a known breaker. Some modding archives still host the "pre-MULTi8" language.dll file as a restoration patch.
Since this update is no longer officially distributed as a standalone package (Aerosoft and Steam only serve the latest version), archivist communities have preserved it. You may find it on:

For the dedicated virtual bus driver, OMSI 2 is more than a game; it is a simulator with a cult-like following, known for its punishing realism and a modding community that has kept it alive for over a decade. However, navigating its update history is often as complex as navigating the streets of Berlin-Spandau.
Buried in the patch notes archives and repack forums lies a specific, curious entry: OMSI 2 Steam Edition MULTi8 Update 15.03.2018. To the average player, it looks like a standard localization patch. To veterans and mod archivists, it represents a critical turning point in the game’s accessibility—and a notorious headache for mod compatibility.
Log entry – Klaus M., virtual driver since 2014
“I launched Berlin-Spandau after the update. At first, I noticed nothing — the SD200’s engine growled the same, the rain still beaded lazily on the windshield. But then, at the Ruhleben terminal, the framerate didn’t stutter. Five minutes later, I passed the notorious crossing at Heerstraße — usually a slideshow — smooth as 60 Hz. The AI Mercedes didn’t suddenly flee into the oncoming lane. My passengers got off without teleporting. For the first time in months, I finished a full 90-minute route without a crash. The 15.03.2018 patch? It’s the grease in the gearbox we begged for.”
