🔧 Maintenance
Service Intervals
Oil Change Interval:
Typically 5,000 - 10,000 km or 6-12 months, depending on usage and oil type.
Suspension Sphere Check:
Regular checks for correct pressure are crucial, often recommended every 20,000 - 30,000 km or as indicated by ride height anomalies.
Fluid Specifications
Engine Oil:
Refer to manual for specific grades (e.g., API SG/SH, SAE 10W-40 or 15W-50 depending on climate/engine).
Hydropneumatic Fluid:
Citroën LHS (LHM - Liquide Hydraulique Minéral) is critical. Never substitute mineral-based hydraulic fluid for DOT 3/4 brake fluid or vice versa.
Coolant:
Ethylene glycol-based antifreeze mixed with distilled water.
Brake Fluid:
DOT 3 (for standard brake circuits where not mixed with LHM; LHM is used for suspension, steering, and brakes in a combined system).
Known Issues
Suspension Problems:
Loss of ride height, bouncing, pump whine, leaks from spheres or hoses, control valve issues. LHM contamination can be detrimental.
Electrical Quirks:
Aging wiring looms, corrosion in connectors, issues with dashboard warning lights, and central locking can occur.
Engine Management:
Carburetor tuning for non-injection models, fuel pump issues on older injection systems.
Steering Issues:
Power steering leaks, stiff steering, pump failure, steering rack wear.
