Description
Multifunction COM2005 DELPHI control block for Citroën and Peugeot vehicles. Controls lights, fog lights, car radio, cruise control and car radio (it is necessary to add or transfer the stalk/controller), front and rear wipers, horn.
This multifunction stalk and control cluster is designed for a range of Citroën and Peugeot models and gathers many driver controls into a single COM2005 Delphi module. Ideal for professional garages and experienced DIY mechanics, the unit operates exterior and interior lighting, fog lamps, wiper functions, horn and some steering-column-mounted controls including cruise control and radio interface (note: radio interface or its stalk may need to be added or transferred). Many customers search by part number (see Technical Information below), so matching the code is the quickest way to find correct replacement parts.
Replacement Overview
Replacing the COM2005 control block involves removing the steering column trim to access the stalk cluster, unplugging the wiring harness and replacing the module. Typical steps: disconnect the battery, remove upper and lower steering column covers, unclip the stalk assembly, disconnect electrical connectors, fit the new unit and reassemble. After replacement some functions may require initialization or configuration with a PSA diagnostic tool (DiagBox/Lexia/PP2000) to restore full functionality (e.g. cruise control, steering column adaptations).

Installation Recommendations
- Always disconnect the vehicle battery before starting work and wait a few minutes to allow restraint systems to power down.
- Handle airbag and clock-spring components with care; avoid rotating the steering wheel with the steering column disassembled.
- Inspect connectors and wiring for corrosion or damage; replace any brittle or corroded plugs to prevent future faults.
- After fitting, check all functions (lights, wipers, horn, cruise control, radio controls) and perform any required adaptations/coding with a compatible diagnostic tool.
- If unsure about coding or diagnostics, have the final initialization performed by a technician with PSA service equipment (DiagBox/Lexia/PP2000).
Most Common Failure Reasons
- Contact Wear: Frequent use of stalk switches leads to worn internal contacts or intermittent connections.
- Moisture Ingress and Corrosion: Water or condensation can corrode contacts and connector pins, causing electrical faults.
- Mechanical Damage: Physical impact or aggressive removal/installation can break switch mechanisms or plastic mounts.
- Solder Joint Cracks: Vibration over time can lead to cracked solder joints on the module’s circuit board, producing intermittent failures.
- Connector Faults: Bent or oxidized connector pins interrupt signals between the module and vehicle wiring.
Replacing the COM2005 unit with a correctly coded and fitted part restores grouped steering-column functions and improves reliability. Matching the part number is the most reliable method to identify the correct replacement.
