Symptoms of a Faulty Steering Gear

Owners of affected vehicles may notice a "Check Control message" appearing on the instrument cluster. Additionally, they might experience a "minimally changed steering feel" while driving. These symptoms indicate a potential issue with the steering system, which is the 2025 BMW X3 steering gear fault.

The Root Cause

The underlying cause of this issue is identified as a faulty sensor within the steering gear. This sensor is responsible for detecting the driver's steering request, and its malfunction can lead to the observed symptoms and necessitate the delivery stop.

Repair Procedure Summary

The repair for the 2025 BMW X3 steering gear fault involves replacing the entire steering gear assembly. Technicians must follow the specific repair instruction REP32 13 572, titled "Replace electrical steering box (EPS)".
