Expeditions steam build ID 17182680. It is the latest standard branch as of 2025.3.11.


To re-create the problem, drive U2450L in manual low gear or high gear mode to exclude gear shift sfx, and you will have a perfectly silent vehicle.



When driving Mercedes-Benz Unimog U2450L in cockpit mode 1. it has no engine running sound . 


2. it does has all other engine sounds like engine idle sound, engine gear shift sound, throttle UP during gear shift, etc.


When driving Mercedes-Benz Unimog U2450L in default 3-rd person view, all engine sfx sounds are working correctly.
