Near the end of the movie, when Stubbe and Zimmermann chase to the old railway garage, they are in a car with Hamburg license plates (HH-KX 927). However, at approximately 82:45 minutes, there is one shot from inside the car where you can see the green environmental vignette on the windshield, and it is for a car registered in the city of Braunschweig (BS-CA 5109).
