9C98 е дефект зачуван во меморијата на вашето BMW (ISTA код на дефект, а не стандарден OBD-II P-код).
Што значи: Panoramic sunroof — Hall (position) sensor fault. The Hall sensors tell the roof control unit the glass position, speed and direction (also for anti-trap protection). A fault can make the roof misbehave or refuse to close/open correctly. Often fixed by re-initialising (normalising) the sunroof; if it returns, the sensor/motor or roof control unit needs checking. Not a safety-critical engine fault.
