Description
Roof Control Unit For PEUGEOT 307 CC
High-quality Roof Control Unit designed for the Peugeot 307 CC convertible. This control module manages the folding roof sequence, coordinating motors, limit switches and safety interlocks to ensure smooth, reliable operation of the hard/soft top mechanism. Commonly searched under part numbers 9647538580 and 6545N1, this unit is intended for professional workshops and experienced DIY mechanics who service Peugeot/Citroën vehicles.
Key Features And Benefits
This roof ECU controls the order and timing of the roof motors, monitors position sensors and interlocks with door and boot latches to prevent damage during operation. Replacing a faulty unit restores correct sequencing, eliminates erratic roof behavior and resolves failures caused by electrical faults or corrosion in the original module. The module is compatible with vehicle systems used by Peugeot under the Stellantis group branding.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 307 CC
- Product Codes: 9647538580, 6545N1
- Other Numbers: Commonly referenced under tags 6545N1 and 9647538580
Installation Recommendations
Before beginning any work, always disconnect the vehicle battery and follow the manufacturer’s safety procedures. Typical replacement steps:
- Remove interior trim panels or luggage compartment lining to access the roof control unit (location varies by body and trim).
- Document connector positions and routing; label connectors if necessary.
- Unplug electrical connectors and remove mounting fasteners securing the control unit.
- Install the replacement unit, secure fasteners and reconnect all plugs, ensuring connectors are clean and fully seated.
- Reassemble trim and perform a functional test of the roof cycle, checking for correct sequencing and absence of fault indicators.
Use appropriate workshop tools and diagnostic equipment if available. When reassembling, ensure grommets and seals are intact to prevent water ingress to the connectors and module.
Why This Part Fails Most Often
- Moisture Ingress And Corrosion: Exposure to water and condensation can corrode connector pins or internal components, causing intermittent or permanent failure.
- Electrical Surges Or Short Circuits: Faults in wiring or motor overcurrent events can damage the control electronics.
- Mechanical Stress And Vibration: Repeated roof operation and vibrations can fatigue solder joints or connector contacts over time.
- Faulty Sensors Or Wiring: Malfunctioning limit switches, position sensors or damaged harnesses often present as ECU faults even when the unit itself is intact.
Notes For Mechanics And DIY Enthusiasts
Because this unit directly controls mechanical movements and safety interlocks, verify motor and sensor integrity before concluding the ECU is defective. Searching by part number (9647538580 / 6545N1) speeds up identification and ensures you receive the correct replacement. After replacement, run at least one full roof cycle to confirm proper operation and check for stored fault codes with appropriate diagnostic tools.
Buy with confidence if you require a direct-fit roof control module for Peugeot 307 CC applications—ideal for professional garages and skilled DIY repairs.
