“Missing DLC Detected” in Euro Truck Simulator 2: Causes, Solutions, and What It Really Means

For the dedicated virtual trucker, few sights are as jarring as the red-lettered warning: “Missing DLC Detected” accompanied by the ominous advisory that “Some DLCs are missing. Your game save might include progress from DLCs that are no longer available or are disabled.”

This message does not mean your save file is corrupted or that your game is broken. Instead, it is a safeguard—a digital checkpoint flag put in place by SCS Software to prevent catastrophic load failures. Here is a comprehensive breakdown of why this happens, how to fix it, and what you stand to lose.

How to Prevent This Error in the Future

Once you fix the error, here is how to ensure you never see the "euro truck simulator 2 missing dlc detected" message again.

1. Verify DLC Ownership & Installation (Steam)

6. Reinstall Specific DLC

Common Causes

  1. Mod Dependencies (Most Common) The most frequent cause is an active mod that requires a specific map or cargo DLC to function. For example, many "ProMods" add-ons or custom map extensions require the Scandinavia, Going East!, or Vive la France! DLCs as a base. If you have the mod enabled but do not own the required DLC, the game will warn you that assets are missing.
  2. Steam Sync Issues Occasionally, Steam may show that you own a DLC, but the files were not downloaded correctly, or the license has not been refreshed. This can happen after a purchase or if Steam was launched in offline mode.
  3. Mismatched Save Files If you have downloaded a save game from the internet or are trying to load a profile that you played on a different computer, the profile may contain trucks or cargo from DLCs you do not currently own.

The ProMods Complication

For the hardcore simulation community, the "Missing DLC Detected" error takes on a terrifying new dimension when ProMods (the massive map mod) is involved.

ProMods requires every official map DLC to function. If you are missing Vive la France!, Scandinavia, Going East, Italia, Iberia, Road to the Black Sea, West Balkans, and Iberia, ProMods will refuse to load.

The ProMods Specific Error: If you see "Missing DLC Detected" while running ProMods, but you own all the DLCs, your load order is wrong. The ProMods files must load above the def file but below the map DLCs in the Mod Manager.

How to fix ProMods DLC error:

  1. Ensure you own all Map DLCs (Check the ProMods website for the current list).
  2. In the ETS2 Mod Manager, press the "Load Order" button and sort alphabetically, then manually adjust to the order specified on the ProMods forum (usually: ProMods Definition, Map, Models 1-3, Assets).
