Climate Control Repair:
Troubleshooting and repair of the heating and ventilation systems, including component replacement.
Depth:
High - Covers from basic maintenance to complex overhauls and diagnostics, suitable for professional technicians and advanced DIY mechanics.
Oil Change Interval:
Typically 7,500-10,000 km (4,500-6,000 miles) or annually, whichever comes first. Manual will specify exact intervals based on usage.
Timing Belt Interval:
For gasoline engines, replacement typically around 80,000-100,000 km (50,000-60,000 miles). Diesel engines may use timing chains or belts with different intervals. Manual is critical for this.
Suspension Fluid:
Citroën LDS fluid (or compatible equivalent). The manual will specify the exact type and part number.
Engine Oil Type:
Viscosity and API/ACEA specifications will vary by engine. Typically 10W-40 or 15W-40 for naturally aspirated engines, potentially 5W-40 or 10W-40 synthetic for turbo engines. Manual is definitive.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid. Manual will specify the required type and replacement interval.
Suspension Sphere Wear:
Hydropneumatic spheres can degrade over time, leading to a harsher ride or hydraulic system issues. Regular testing and replacement are recommended.
Hydropneumatic Pump Failures:
The main hydraulic pump is a critical component and can require rebuilding or replacement if it fails.
Electrical Gremlins:
As with many older European cars, electrical connections and wiring harnesses can degrade, leading to intermittent faults.
Rust:
Body corrosion, particularly in wheel arches, sills, and around windows, is a common concern for vehicles of this age.
