The Citroen DS4 shares most of it's mechanical and electrical parts with the C4 so we are able to provide support for both car variants on this site.

We are independently owned and run to help provide support for C4, C4 Picasso and DS4 owners. Our mission is to let current (and past) owners help each other and we have now built up over ten years of experience on issues with the Citroen C4 range.

The most obvious benefit of Premier Membership is the ability to view and download Vehicle Handbooks, Guides and Technical Documents. With Premier membership on C4owners.org, you have access 24 hours a day, seven days a week.

We would also sincerely appreciate any donation you feel able to make to keep the site running. Our overheads are increasing year on year – we have not increased the cost of Premier Membership and do not wish to do so, as we believe the site should be accessible to all. Any donation, no matter how small, is gratefully received and valued by us here at C4owners.
