Fitment And Function
Designed for Citroën C5 II and Peugeot 407 models equipped with ESP. The stalk assembly controls fog lights, onboard computer functions, rear wiper, rain sensor input and ESP-related switching. It is a multi-function switch block that sits on the steering column and communicates with the vehicle’s body and stability systems via a multi-pin connector.
Replacement Procedure
Replacement requires basic to intermediate skills. Recommended steps: disconnect the negative battery terminal and wait at least 10 minutes to allow safety systems to discharge; remove the steering column trim covers; note and/or mark the position of the steering wheel if necessary; remove the retaining screws for the stalk assembly; unplug the electrical connector(s) and remove the old unit; fit the replacement, reconnect the connector(s), reassemble the trim and reconnect the battery. Check all functions (lights, wipers, trip computer, rain sensor and ESP) after installation. If you are unsure about working near the airbag system, consult a professional.
Installation Recommendations
Use appropriate Torx/screwdriver bits to avoid damaging trim screws. Inspect connector pins for corrosion and clean with electrical contact cleaner if needed before reassembly. Tighten screws to a firm feel without over-torquing plastic parts. Perform a full functional check after installation and, if the vehicle reports faults, clear codes and retest with an OBD tool.
Why This Part Most Often Fails
Typical causes of failure include wear of internal contacts from long-term use, contamination or corrosion of connector pins, mechanical damage to plastic levers or clips, and moisture ingress from a leaking windshield area. Frequent use of wiper and light functions accelerates wear. Electrical faults in the steering column wiring or intermittent connector contact can also cause malfunctioning of one or more functions.
