📖Citroën C5 II: German-inspired styling and the swansong of Hydractive suspension

Revealed in 2008, the second-generation Citroën C5 marked an audacious departure with sharp, Germanic styling, an elegant concave rear window and a premium interior. Available as an executive saloon and sculpted Tourer estate, it stands as the final chapter in Citroën's iconic oleopneumatic lineage with optional Hydractive 3+ suspension. Meticulous Citroën C5 maintenance ensures this majestic mile-muncher stays in peak operational condition.

Power came from proven units, including the indefatigable 2.0 HDi (140 and 163 hp), the refined 2.2 HDi biturbo and the muscular 3.0 V6 HDi pushing 240 hp. Long journeys were made effortless by the Aisin AM6 six-speed automatic gearbox, while entry models rode on conventional steel coil springs, giving buyers the choice between classic mechanical simplicity and cutting-edge hydraulic float.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability

Last production Citroën to feature legendary Hydractive oleopneumatic suspension with dynamic Sport and Comfort modes.
Executive cabin build quality and sound deadening rival contemporary German premium saloons.
The 2.0 HDi 163 diesel paired with the AM6 automatic provides outstanding long-distance reliability and torque.
Distinctive exterior styling with its concave rear glass and sculpted Tourer estate silhouette.

Chronic weak spots

Keep an eye on

Power steering rack: check steering pinion seal and rack boots for hydraulic fluid leaks (a known C5 II weak point).
Hydractive 3+ suspension: inspect front and rear LDS hydraulic cylinders, return pipes and electronic height sensors.
AM6 automatic gearbox: change ATF fluid every 80,000 km to prevent valve body sticking and jerky shifts when warm.
EGR valve (HDi engines): monitor soot buildup and clean valve periodically on vehicles used primarily for short trips.
Electric window regulators: check front window cables and switches for fraying, snapping or sticking in window channels.

Critical deadlines

Do not miss

Inspect the steering rack for hydraulic fluid weeping at every engine oil service to catch seal failure early.
Drain and refill AM6 automatic transmission fluid every 80,000 km to extend gearbox valve block lifespan.
Replace the 2.0 HDi cambelt kit and water pump every 10 years or 160,000 km (earlier under severe conditions).
Lubricate door hinges, window guide tracks and tailgate struts annually to prevent cable binding and motor burnout.
