C0526 is the base code for the steering angle sensor module, used when a fault is reported without a more specific failure type. MINI documents it for the 2017 Countryman F60 plug-in hybrid: an on-board diagnosis error in the electric power steering software stored C0526, readable only with a generic OBD tool, and lit the check-engine lamp. It occurred after the car had been in transport mode and the terminals were switched twice without steering; turning lock to lock, a driving-readiness routine and later software clear it. Sensors such as Bosch's derive the absolute angle from two gear-driven magnets read by GMR elements and send angle and rate over CAN. Typical consequences are an ESC lamp and, on EPS cars, reduced assist.

Likely causes

Power steering software error (MINI F60 PHEV 2017)
Supply loss or battery disconnection without relearning
Internal fault in the steering angle sensor module

Symptoms

  • Check-engine lamp on (MINI F60 PHEV)
  • ESC warning lamp on, stability control limited
