How can you avoid creating noise?

You answered correctly by choosing to fill empty compressed air tanks from a stationary facility and replacing worn-out side latches. According to German traffic rules, avoiding unnecessary noise is important, especially in residential or quiet areas. Filling air tanks at a stationary facility is quieter than using the vehicle's compressor. Also, worn-out side latches can cause rattling noises; replacing them helps reduce this noise. Allowing the engine to idle during longer waits, however, increases noise and emissions, so it should be avoided. By following these measures, you contribute to noise reduction and a more environmentally friendly driving experience.
