I'm sorry to hear that you are experiencing issues with your new BMW X7. It can be frustrating to have issues with a new vehicle, especially if they are not easily resolved. The Kafas camera, or Kamera für Fahrerassistenzsysteme, is a camera that is used for various driver assistance and safety systems in your X7. If the Kafas camera is not functioning properly, it can cause problems with these systems, including the "Driver Assist support reduced" warning that you have experienced.
It is not uncommon for there to be issues with new vehicles, and it is usually possible to resolve them through repairs or replacements. If the dealership has already replaced the Kafas camera and is still experiencing issues, it is possible that there may be a problem with the camera itself or with the system that it is a part of. In this case, it may be necessary to order a different camera that is compatible with your X7. It can be frustrating to have to wait for parts to be shipped from Germany, but in some cases it may be the only option to get the necessary repair parts.
I recommend staying in contact with the dealership and following their recommendations for repairs. They should be able to provide you with updates on the status of the repair and let you know when the new camera is expected to arrive and be installed. If you have any concerns or questions about the repair process, don't hesitate to ask the dealership for clarification.
