On the 2001-2017 Citroen C5, the C5 Hydractive III+ suspension is Citroën at its most complex, with multiple spheres controlling ride height, comfort, and body roll. The nitrogen-charged spheres lose pressure over time, transforming the famously smooth ride into something harsh and uncontrolled.

This issue also affects: Citroen C5 Aircross

Common Symptoms

  • Harsh ride
  • Vehicle sits low
  • Suspension warning light
  • Excessive body roll
  • Nose dive under braking

How to Fix

Replace all suspension spheres as a complete set for consistent ride quality. Check the LDS fluid level and condition. Test the hydraulic pump output pressure. Budget for sphere replacement every 60,000-80,000 miles.
