Mini One Steptronic Clutch Actuator P0900 Fault — Repair Specialist | The Vehicle Check

The Vehicle Check specialises in Mini Steptronic clutch actuator repair and cloning — covering P0900 and related actuator fault codes. Nationwide mail-in postal service with drop off at our Enfield office.

Mini Steptronic Clutch Actuator — What Goes Wrong

The early Mini One and Mini Cooper Steptronic uses a robotised single-clutch automated gearbox — not to be confused with the later 6-speed automatic. This system uses an electromechanical clutch actuator to manage clutch engagement. P0900 — Clutch Actuator Circuit Open — is stored when the actuator motor circuit fails due to internal motor wear or circuit board component degradation.

Our full clutch actuator repair and cloning service covers all Mini Steptronic automated manual gearbox variants. If you are unsure whether your Mini has the automated manual or a conventional automatic, contact us with your gearbox type and we will advise.
