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.
