C1A00 on MINI
Stability Control System Fault
C1A00 on MINI vehicles indicates stability control system fault. Au7o has documented this code across 1 MINI model — most commonly on Cooper. This is a chassis/stability-control code that signals a general fault within the electronic stability control system — the network of sensors and the controller that keep the vehicle from skidding or losing traction during hard cornering or slippery conditions. C1A00 typically means the stability control module detected an internal fault or a problem somewhere in the system it can't fully resolve, so it may disable stability and traction control and turn on the related warning lights. Importantly, C1A00 is a manufacturer-specific code and its precise meaning varies by brand, and the full code often includes additional sub-numbers needed to pinpoint the exact fault. Because it's broad, an accurate diagnosis usually requires a capable scan tool to read the extended code and any companion codes. Typical repair costs on MINI range from $1,500 to $3,500, depending on the specific model and root cause.
Common Causes of C1A00
- •Internal stability control module fault
- •Companion sensor faults (wheel speed, steering angle, yaw/lateral) triggering the system
- •Wiring, connector or ground problems in the stability control circuit
- •Low system or battery voltage / charging issue
- •Module software, calibration or configuration fault
- •Damaged or unplugged sensor harness after service
- •Faulty ABS/stability hydraulic control unit (less common)
C1A00 on MINI by Model

- Electric Power Steering Rack Failure2014-2025
F56 generation Coopers experience electric power steering rack failures. The EPS motor or control module within the rack fails, causing sudden loss of power assist or intermittent heavy steering. This is a safety concern as it can happen while driving.
