ETS2 1.54 mods: compatible mods and how to play 1.54

ETS2 1.54 mods

Euro Truck Simulator 2 1.54 came out on April 1, 2025. According to the SCS blog, PhysX became the default physics engine instead of Bullet, the cargo system was simplified and the truck settings were gathered into a single menu. The Driving Academy also added the Volvo FH Series 5 and 6 and the Iveco S-Way.

On Holymod, 1.54 is the latest declared version of Interior Addon by Wolli, one of the most viewed cab accessory packs on the SCS forum. On newer versions, remember that maps and complex trucks usually need the exact version; skins and sounds often work even if the Mod Manager shows a warning.

How to play ETS2 1.54 on Steam

If your mods don't work on the latest version yet, SCS Software keeps previous game versions on Steam so you can keep using them. No password needed.

In your Steam Library, right-click Euro Truck Simulator 2 and open Properties.
Open the Betas tab and pick temporary_1_54 from the drop-down (it shows as “1.54.x for incompatible mods”). If you can't see it, restart Steam.
Wait for Steam to download that version and open the game.

Before switching versions

Back up your profiles (the Documents/Euro Truck Simulator 2/profiles folder, or steam_profiles if you use Steam Cloud): a save made on a newer version may not load on an older one.
Steam Workshop mods always download in their latest version. They'll only work on 1.54 if their author includes a package for that version; if not, download the older file by hand from the official source listed on each mod page.
DLC released after 1.54 may not work on that version.
This option only exists in the Steam version of the game.
