• Product Codes: 96611303XT, 6242S6
• Additional Numbers: 96486272XT, 6239JP, 6242Z6, COM2003

Installation and Recommendations

Replacement requires careful work around the steering column and airbag system. Recommended procedure:

• Disconnect the vehicle battery and wait at least the manufacturer-recommended time before starting work to avoid airbag deployment and electrical damage.
• Remove lower and upper steering column covers to access the switch assembly.
• Disconnect electrical connectors and remove mounting screws securing the stalk module.
• Install the replacement unit, reconnect connectors, and reassemble covers. Check all functions (indicators, fog lamps, trip computer interactions, rain sensor/ESP signals) after reconnection.
• When work involves steering wheel or airbag removal, use appropriate tools and torque settings and consider professional assistance if unsure.

Common Failure Causes

Steering column switches age through regular use and environmental exposure. Typical failure modes include:

• Wear of electrical contacts or carbon tracks causing intermittent operation of indicators or lighting circuits.
• Mechanical wear in the stalk detents, resulting in a looser stalk feel (as noted for this unit).
• Corrosion or moisture ingress on connectors or internal contacts leading to faults in lighting, rain sensor signal or ESP inputs.
• Contact oxidation from long service life or exposure to humid conditions.

Why This Part Fails Most Often

Frequent operation (indicators, wipers, fog lights) combined with dust and humidity accumulation inside the column leads to contact wear and mechanical play. The indicator stalk is a moving part that commonly shows looseness before full functional failure, which aligns with the condition described for this used unit.

Who Should Fit This Part

Suitable for experienced DIY mechanics and professional workshops. If the job requires steering wheel or airbag removal, a trained technician is recommended to ensure safety and correct reassembly.

Notes

• Unit Condition: Used. Functionality: Fully functional according to seller description; indicator stalk may be slightly loose but operates without slipping.
• Search Tips: This switch is often identified by the part numbers listed above and by the designation COM2003 or Valeo COM2003.

High-quality used steering column controls (stalks) designed for Citroën C5 II and Peugeot 407 with ESP. This Valeo COM2003 unit combines multiple functions into a single module: control of front fog lamps, onboard trip computer, rain sensor interface and ESP-related signals. The part is commonly searched under reference numbers such as 96611305XT or COM2003, making it easy to find for workshops and DIY enthusiasts.

Compatibility and Application

Fits vehicles equipped with Valeo COM2003 steering controls and ESP wiring harness. Primarily compatible with Citroën C5 II and Peugeot 407 models. Ideal for mechanics and car owners performing electrical or steering column repairs. Often referenced by product code 96611305XT or by internal Valeo designation COM2003.

How It Works

The unit provides multi-function switching from the steering column: activation of front fog lamps, control inputs for the onboard computer, signals for the rain/light sensor and communication with the ESP system. The indicator (turn signal) stalk is integrated into the assembly and may show mechanical looseness over time while remaining operational.

Replacement Procedure

• Disconnect the vehicle battery before beginning work to prevent short circuits and airbag deployment.
• Remove the steering wheel airbag and trim panels according to manufacturer procedures.
• Unscrew the steering column covers to access the stalk assembly.
• Unplug electrical connectors and remove the mounting screws holding the stalk module.
• Fit the replacement unit, reconnect all plugs and reassemble in reverse order. Verify all functions (indicators, fog lights, trip computer inputs, rain sensor response, ESP messages) after installation.

Installation Recommendations

Always follow manufacturer torque settings and assembly sequence for steering column components. Use proper tools to avoid damaging plastic clips and electrical connectors. After installation, perform a full functional check: indicators, fog lamps, trip computer commands and any related dashboard messages. If you encounter ESP or airbag warnings, re-check connectors and consult diagnostic equipment suitable for Citroën/Peugeot systems.

Common Failure Causes

These steering column controls commonly fail due to mechanical wear (worn detents and springs in stalks), ingress of moisture or dirt into switches, and contact oxidation causing intermittent electrical signals. Frequent use of turn signals and exposure to humidity accelerate wear. Loose indicator stalks are often the result of worn internal pivots rather than electrical faults.

Benefits of Replacing This Unit

• Restores reliable control of fog lights, trip computer functions and rain sensor signalling.
• Resolves intermittent indicator operation caused by worn mechanical components.
• Quick swap for workshops familiar with Citroën/Peugeot steering column servicing.
