MINI Cooper · 2014–2024
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.
Common Symptoms
- Power steering warning light
- Sudden heavy steering
- Intermittent power steering loss
- Steering wheel vibration
- Clunking noise when turning
How to Fix
First have the fault memory read with MINI diagnostics. MINI service bulletin SI M32 01 16 (fault 4823FA, assist drops after repeated parking maneuvers) is fixed with a software update, not a new rack. SI M32 01 14 (assist unavailable at start-up) calls for a new EPS rack on cars built up to 06/14/2016, and a software or ignition-cycle procedure on later cars. Where a new rack is needed, note that the EPS motor is integrated into the rack and cannot be serviced separately. Some rebuilt units are available at lower cost.

Frequently asked questions
What does C1A07 mean?
C1A07 stands for "Stability Control Lateral Acceleration Sensor." This is a manufacturer-specific chassis code indicating a fault related to the stability control system's lateral acceleration (G) sensor. This sensor measures sideways force on the vehicle during cornering, and the Electronic Stability Control system uses it together with the yaw and steering-angle inputs to decide when to intervene. C1A07 sets when the module detects an implausible, out-of-range, or unreliable signal from that sensor. Stability and traction control are typically disabled (warning light on) while normal braking and driving continue.
What are the most common causes of C1A07?
The most common causes of C1A07 are: Faulty lateral acceleration (G) sensor or combined yaw/G sensor, Sensor calibration/zero-point not learned after repair, Wiring or connector fault to the sensor, Low system voltage affecting sensor output, Loose or improperly mounted sensor, Communication fault between sensor and stability module, Faulty ABS/stability control module. The specific cause varies by vehicle.
How much does it cost to fix C1A07?
Repair costs for C1A07 range from $1,500 to $3,500, depending on the vehicle and root cause.
