Description
Valeo steering column stalks for Citroën C4, C4 Picasso and Grand Picasso first series. They control fog lights, front and rear wipers, the wiper sensor and the trip computer.
Product Description
High-quality Valeo steering column stalks designed for first-generation Citroën C4, C4 Picasso and C4 Grand Picasso. These multi-function stalks operate front and rear wipers, washer functions, fog lights and provide inputs to the trip computer and wiper sensor systems. Ideal for professional garages and experienced DIY mechanics who need a direct-fit replacement part often searched by product code.
Key Features
- Direct replacement for original stalk switches used on compatible Citroën models.
- Controls fog lights, front and rear wipers and washer jets.
- Provides signals for the wiper sensor and trip computer.
- Robust OEM-quality switch mechanism from Valeo for reliable operation.
- Commonly referenced by product numbers for fast lookup and fitting.
How It Is Replaced
Replacement is straightforward for a trained technician: disconnect the battery, remove the lower and upper steering column covers, unplug the electrical connector(s) to the stalk, unclip or unscrew the stalk from the column and install the new unit in reverse order. If removal of the steering wheel or airbag is required, follow manufacturer procedures and safety precautions—airbag handling should be performed by trained personnel.
Installation Recommendations
- Disconnect the negative battery terminal before starting work to avoid short circuits and accidental airbag deployment.
- Work on a static steering wheel position and mark the steering wheel center if it must be removed.
- Inspect connectors and wiring for corrosion or damage before fitting the new stalk.
- After installation, check all functions: intermittent and continuous wiper speeds, washer pumps, rear wiper and fog light activation, and trip computer signals.
- If any functions are controlled via body modules, verify fault codes with a diagnostic tool after fitting.
Why The Part Fails
- Electrical Wear: Repeated switching causes contact wear and increased resistance, leading to intermittent operation.
- Moisture Ingress: Water or condensation can corrode internal contacts and connectors.
- Mechanical Wear: Internal springs and plastic detents can fatigue or break after extended use.
- Connector Issues: Loose or oxidized connector pins give unreliable signalling to control units.

Notes For Professionals
These stalks are frequently searched by their product numbers, so include the codes in your parts lookup to find the correct unit fast. When replacing components that interact with vehicle electronics, always clear and read fault codes after fitment and verify proper communication with the vehicle’s on-board systems.
