Rust Corrosion:
Common issue in older vehicles, particularly around wheel arches, sills, and floor pans.
Hydropneumatic System:
Potential for leaks in hoses, seals, or spheres; loss of ride height. Requires specialized knowledge to maintain.
Cooling System:
Air-cooled engines are less prone to leaks but can overheat in extreme conditions or with poor airflow. The oil cooler can become clogged.
Electrical Gremlins:
Older wiring and connectors can degrade, leading to intermittent issues.
Citroen Philosophy:
Known for avant-garde design, aerodynamic efficiency, and innovative engineering, particularly hydropneumatic suspension.
