Problems with Mod (Car Mechanic Simulator 2018)

Greetings!

Added some BNV from the workshop on the official Steam. After buying this car at auction, I get into the garage and give an error: No parts or additions.

As I understand it, there is no engine that is installed in this car. And two options:
1) try to reinstall the add-on
2) play as is.

You can play, but I would like to disassemble the correct engine.

Help with a solution, please!
