Technical Information

• Manufacturer: Valeo
• Model: Citroën C5 II; Peugeot 407
• Product Codes: 96592428XT, 6242S5, COM2003
• Additional Numbers: 6239JQ, NFP

Fitment

Direct fit for Citroën C5 II and Peugeot 407 MPI models equipped with Valeo COM2003 electrical architecture and ESP. Verify the physical connector and mounting arrangement before installation — this part is typically cross-referenced by the listed product codes.

Installation

Recommended general procedure for replacement (work should be performed by a qualified technician or an experienced DIYer comfortable with steering-column work):

• Disconnect the negative battery terminal and wait the manufacturer-recommended time to ensure airbag circuits are safe.
• Remove the steering wheel airbag and steering wheel following manufacturer instructions to avoid damage to SRS components.
• Remove upper and lower steering column shrouds to access the stalk assembly.
• Unplug electrical connectors and release retaining clips securing the stalk unit.
• Fit the replacement stalk assembly, secure clips, and reconnect all connectors.
• Reassemble the column covers and refit the steering wheel and airbag. Reconnect the battery.
• Test all functions: indicators, fog lights, wipers, trip computer controls, rain sensor response and ESP-related feedback. Clear any stored fault codes with a diagnostic tool if necessary.

Mounting Recommendations

• Always disconnect the battery before starting work and follow the vehicle manufacturer’s safety procedures to prevent SRS damage.
• Inspect connectors for corrosion or damaged pins and clean before reassembly to ensure reliable electrical contact.
• Handle the airbag and steering wheel with care; do not place the airbag face down.
• If fault codes or warning lights remain after replacement, use a diagnostic scanner to read and clear codes and verify sensor calibrations.

Why It Fails

Multifunction stalks commonly fail due to mechanical wear of internal contacts and levers, contamination from moisture or dirt, broken plastic detents or springs from repeated use, and connector corrosion. Intermittent operation, stuck or loose stalks, or loss of specific functions (e.g., fog lights or wiper control) are typical symptoms. Heavy use, exposure to moisture, and mechanical stress during steering column repairs increase the likelihood of failure.

Notes For Professionals

Because this is a used unit, expect slightly reduced stiffness compared with a new switch; however, full electrical functionality is maintained. Keep spare fasteners and inspect the steering column for worn mounting points while replacing the stalk to ensure a long-lasting repair.

Product Overview

Replacement steering column stalk control unit (Valeo COM2003) designed for Citroën C5 II and Peugeot 407. The module groups multiple switch functions on a single stalk assembly to operate fog lights, the onboard trip computer, rear wiper, rain sensor interface and ESP-related switch functions. Supplied as a used unit that is functional and suitable for mechanics and experienced DIYers looking for an OEM-fit replacement by part number.

Key Features

• OEM Valeo COM2003 design for direct fitment on compatible models.
• Controls fog lights, trip computer, rear wiper, rain sensor input and ESP switch functions.
• Delivered as a used, working part — may show cosmetic wear and will not be as stiff as new.
• Often Searched By Part Numbers For Fast Identification: 96611302XT, 6242S5, 6239JQ, COM2003.

Technical Information

• Manufacturer: Valeo
• Model: Citroën C5 II, Peugeot 407
• Product Codes: 96611302XT, 6242S5
• Other Numbers: 6239JQ, COM2003

Function And Role

The stalk controller houses multiple electrical switches and signal contacts that send commands to lighting modules, the instrument cluster and vehicle stability systems. It provides manual inputs for fog lamps, selects and scrolls trip computer menus, commands the rear wiper, and relays rain sensor and ESP switch signals to the corresponding control units. Because it is a multi-function assembly, a single faulty stalk can affect several vehicle systems.

Common Faults And Causes

• Wear Of Internal Contacts: Repeated use causes contact pitting or loss of spring tension, leading to intermittent or non-responsive switches.
• Moisture Or Corrosion: Water ingress or corrosion at connector pins can interrupt signals.
• Mechanical Damage: Broken plastic tabs, worn detents or snapped levers from rough handling or previous removal.
• Wiring Connector Issues: Bent pins or poor mating in the column connector can cause faults that mimic a failed stalk.

Replacement Procedure

Typical replacement steps (general guidance; follow manufacturer repair manual for exact procedure):

• Disconnect the battery before starting to avoid short circuits and airbag deployment.
• Remove the steering wheel airbag and steering wheel if required by the model (follow safety procedures).
• Unscrew and remove the upper and lower steering column covers to access the stalk mounting.
• Unplug the electrical connector(s) from the stalk assembly and release any retaining clips or screws.
• Remove the old stalk, install the replacement unit in reverse order, ensuring all connectors are fully seated and locking tabs engaged.
• Reconnect the battery and verify all functions (fog lights, trip computer operations, rear wiper, rain sensor input and ESP switch) before refitting covers.

Installation Recommendations

• Always Disconnect The Battery Before Working On The Steering Column.
• Use The Correct Tools And Follow Citroën/Peugeot Service Procedures To Avoid Damaging Airbag Components Or Steering Electronics.
• Inspect Connectors For Corrosion Or Bent Pins And Clean Contacts If Necessary.
• Test All Functions Immediately After Installation And Before Final Reassembly.
• When Replacing A Used Unit, Check Mechanical Fit And Detents; Minor Play Is Common In Used Assemblies.

Why This Part Fails Most Often

Multi-function stalks are subject to frequent mechanical use and environmental exposure. The most common failure modes are worn electrical contacts and mechanical wear of plastic components. Moisture ingress or connector corrosion can accelerate failure. Because one stalk controls several systems, users often notice multiple symptoms (e.g., lighting and wiper issues) stemming from a single failed assembly.

Installation Recommendations

Always disconnect the vehicle battery before starting to avoid short circuits and accidental airbag deployment. Follow the vehicle manufacturer’s procedure for steering wheel and airbag removal. Handle connectors and ribbon cables carefully to avoid damage. After installation, verify all functions (lights, wipers, rain sensor input, trip computer responses and ESP indicators) on the vehicle diagnostic or by direct operation. If the vehicle displays fault codes, clear them and re-check functionality.

Replacement Procedure

1. Disconnect the negative battery terminal and wait at least 10 minutes for residual power to dissipate.
2. Remove the steering wheel airbag following the manufacturer’s safety instructions.
3. Unscrew and remove the steering wheel (mark orientation for correct reassembly).
4. Remove upper and lower steering column covers to access the stalk assembly.
5. Disconnect electrical connectors and release retaining clips securing the stalk module.
6. Install the replacement stalk, reconnect connectors, reassemble covers and steering wheel in reverse order.
7. Reconnect battery and verify all stalk functions and warning lights. Reset any stored faults if necessary.

Common Failure Reasons

• Wear Of Internal Contacts: Frequent use of switches and rotary controls causes contact wear and intermittent signals.
• Moisture And Corrosion: Water ingress or condensation can corrode contacts or connectors, especially in older cars.
• Mechanical Damage: Rough handling during steering wheel/airbag removal or impact damage can break plastic levers or internal mounts.
• Electrical Faults: Short circuits or connector faults can cause partial function loss (e.g., only one wiper speed or fog light command missing).

Lifespan And Maintenance

There is no fixed replacement interval. Failures typically appear after many years of service or at high mileage. Regular inspection and careful handling during steering work extend service life. If controls become sticky, intermittent or mechanically loose, replacement is recommended to restore reliable operation.
