Part Number C4 Grand Picasso

[Samvan77]

Hi there does anyone know where I would be able to source a part number for a light switch stalk unit on a C4 Grand Picasso 2012 model?

There are at least two different types. One has a setting for auto lights, the other doesn't. Which type are you after?

Hi thanks for clarifying that for me. How would I tell them apart?

Not difficult! One has 3 positions; off, sidelights, headlights. The other has 4 positions; off, Auto, sidelights, headlights.

You really need to use your car VIN in the parts diagrams to get the right part number. Then if you are thinking of sourcing a used one you need to use the VIN of the other car to see what part number it has. A quick look at the parts diagrams shows 5 different part numbers depending on if front fog lights are fitted, if it has a rain sensor for the wipers (which would also do auto lights), if there is a coolant level sensor, if it has a piloted gearbox. Note that the light stalk is part of the complete switch unit under the steering wheel and includes the wiper switch. A dealer obviously can provide the part numbers but you can also see the parts diagrams as a free service if you register on the service.citroen site as an other professional non emergency services and as a member of the Citroen Owners Club http://service.citroen.com/do/changerParametres you may need to select your language. Once on the site use your VIN (VIS) top left to find your car.

 

To remove the switch unit the steering wheel cowls are removed, then 2 bolts at the bottom edge of the switch unit and then it should remove up towards the dash. There is a note in the procedures that says you may need a software update but I would think if your car has been dealer serviced any software would already be up to date:

CAUTION : When replacing the switch module at the steering wheel - If the built-in systems interface (BSI) has a 07.3x software edition (In the identification menu ; Using the diagnostic equipment). Download the built-in systems interface (BSI) to update it to the latest version available 9.73.
