The binnacle cowl is only clipped in place, there are no screws to undo.
Just pull the top of the plastic towards you to disengage the clips.
- Remove the binnacle cowl by pulling the top towards you.
With the top part removed the bottom part will now also disengage its clips.
- bottom clips shown
You can then remove the cowl to reveal 3 torx screws that need to be removed.
- Remove the Citroen C3 speedo
There is also an electrical connector clipped to the speedo. The Citroen C3 speedo teardwn topic is here
Refitting:
Attach the electrical connector, fit the torx screws.
Refit the bottom clips first then just push the top away from you and it will pop into place.
If you fit a different speedo (from a different car) the mileage will adjust to the higher of the two, the original (as stored in he BSI or the donor speedo).
