Original transmission control unit (ECU/TCU) for Robotized Sensodrive/2 -Tronic for Citroën C1 and Peugeot 107. Thanks to the exact match of the connectors and codes, it is ideal for quick repair without unnecessary wiring modifications.

The task of this unit is to manage the cooperation of the clutch actuator and the shifting mechanism, evaluate the sensor signals and ensure smooth, safe and accurate shifting. Properly functioning ECU significantly affects the comfort of driving (starting, shifting under load) and the life of the clutch and the actuators.

The exchange is usually approached as a flashing symbol N, the inability to include speed, spontaneous neutral falling, jerky shifting, frequent emergency modes or transmission error messages. In older cars, the units may leave due to temperature cycles, vibrations and humidity. In such cases, the ECU replacement is the fastest way to return the vehicle.

Installation is typically plug -in: Always disconnect the battery before work, release the original unit in the engine compartment, click the connectors and connect the spare part. After installation, it is necessary to make basic settings/calibration (clutch and shift position learning) using a suitable dog diagnostics. For a stable result, we also recommend checking the condition of cabling, connectors, frying and mechanical transmission actuators.

Function And Typical Faults

The SENSODRIVE ECU controls the automated manual transmission: it interprets driver inputs (paddle shifts, selector position), operates electro-hydraulic actuators for gear selection and the clutch, and monitors sensors for speed and position to ensure correct shift timing. Common symptoms of a failing unit include unpredictable or missing gear changes, limp-home mode, error lights related to the gearbox, or complete loss of paddle-shift response.

Why This Part Fails Most Often

• Moisture Ingress And Corrosion: Water or road-splash can corrode connectors or internal components, causing intermittent faults.
• Connector And Wiring Damage: Broken pins, loose connectors or chafed wiring are frequent culprits after impact or prolonged vibration.
• Thermal Stress And Ageing: Repeated heat cycles can degrade solder joints and electronic components over time.
• Electrical Surges: Faulty alternator or jump-starting issues may damage sensitive electronics inside the ECU.

Replacement And Installation

Replacement should be performed by a competent mechanic or experienced DIYer. Typical procedure:

• Park vehicle on level ground, engage handbrake and, if required by manufacturer, put transmission in neutral or park according to service manual.
• Disconnect the negative battery terminal before any work on the electrical system.
• Locate the gearbox ECU (usually mounted on or near the gearbox or within the engine bay — consult vehicle repair manual for exact location).
• Carefully unplug all connectors, noting lock tabs and connector orientation. Remove mounting fasteners and replace with the supplied unit.
• Reconnect connectors securely, refit any removed trim or heat shields, reconnect the battery and perform initial checks.
• After installation, verify gearbox operation through test drive and fault-code scan. In some cases, adaptation or calibration may be necessary.

Recommendations For Installation

• Disconnect The Battery Before Work: Always isolate the battery to prevent short circuits and protect the ECU.
• Inspect Connectors And Wiring: Repair corroded pins and damaged wiring before fitting the replacement unit to avoid repeat failures.
• Use Proper Tools And Follow Manufacturer Procedures: Tightening torques and connector engagement are critical for reliable operation.
• Test Thoroughly After Fitment: Clear any stored gearbox faults, then run a diagnostic scan and a controlled test drive to confirm normal shifting and paddle operation.
• Consider Professional Assistance If Unsure: If adaptation or coding is required, use a workshop equipped with PSA diagnostic tools (DiagBox/Lexia/PP2000) to ensure full integration with vehicle systems.
