Here are some bugs i figured out with the PS4 version:
1: The „turn on lights“ tutorial is missing in german language, only the headline is shown.

2: It is not possible with the Fuel/Service trailer to refuel other or the own Truck. Only repairs are possible (and yes, he was full).

3: If you turn on the Lights, the headlights stays visibly dark.

4: No brake-light animation.
