Yep, it does. This service manual for the 2009 Citroën C5 does cover replacement procedures for the hydraulic pipes and hoses, including those running near the firewall on the right-hand side, which are likely part of the Hydractive suspension or brake assist system depending on your trim.
If you’re seeing a leak in that area, it could be one of the high-pressure return lines or a corroded steel pipe passing through the bulkhead. The manual walks you through how to safely depressurize the hydraulic system, access and identify specific pipe routing, remove and replace hoses or lines using proper flare nut procedures and torque specs, and bleed the system after repair to restore full function.
It also includes line diagrams and pipe routing maps, so you can track exactly which line you’re looking at — helpful since Citroën loves their spaghetti-style hydraulic setups.
