What does the BMW transfer case fault code 44003E mean?

[DelMichael]

BMW transfer case fault code 44003E refers to a shaking phenomenon that occurs when the vehicle is started and the steering wheel is turned to full lock while stationary. Steering wheel shaking: Steering wheel shaking is one of the most common vehicle faults encountered in daily use. If the vibration is only slight, it generally isn't a major concern, as this type of vibration is usually caused by engine resonance. If you're still concerned, you can check whether the engine and transmission mounting brackets are secure, whether the support mounts are reliable, whether the engine mounts are cracked, whether the bolts are loose, and whether the steering gear mounting bolts are loose, etc. Inspection items: If the steering wheel shakes when the car is idling, you should check whether the rubber bushings of the steering linkage are damaged or whether the bolts securing the steering linkage are loose. Additionally, check whether the steering wheel shaking is related to engine idle or the steering gear. Shaking accompanied by noise when the steering wheel is turned to full lock is often caused by steering gear pressure relief or air in the power steering fluid (in mechanical systems).
