Citroën C5 (Mk2) Common Problems & Reliability
The second-generation C5 (X7) was designed to rival German executive cars with its impressive refinement and "Hydractive 3+" suspension. While it offers a peerless ride, it is a complex machine that requires a mechanic who understands its hydraulic systems. Steel-sprung VTR models offer a simpler alternative for those wary of hydraulic maintenance.

Most Common Citroën C5 (Mk2) Faults & Repair Costs
Leaking Front Suspension Struts (Hydractive)
The front struts on Hydractive models are prone to weeping oil. They are non-repairable and must be replaced to pass an MOT.
Visible oil leaks on the driveway, Fluid "dampness" on the strut body, Bouncy or harsh ride
- Inspect front struts for any sign of hydraulic fluid leaks
- Check LDS fluid level in the reservoir
Steering Rack Pinion Corrosion
The steering rack pinion tend to rust, leading to seal failure and significant fluid leaks. New replacements are scarce in the UK.

Independent Wiper Motor Failure
The C5 uses two independent wiper motors. If one fails, the wipers can collide, potentially cracking the windscreen.
One wiper stops moving, Wipers collide and jam, Wiper warning message
