2008 Citroen C5 1.7L Diesel · LC58 LCA

The defining mechanical story for this 2008 Citroen C5 is one of intermittent compliance, having failed three of its last five recorded MOT tests despite none of those failures carrying documented defect notes. A pass on 8 January 2025 was immediately preceded by a fail just five days earlier, and a similar pattern appeared in late 2022 and late 2023, where the vehicle passed one attempt only to fail the next. The absence of recorded advisory or failure items is unusual for a car of this age and mileage, and prospective buyers should be cautious: many retests after an unrecorded initial failure involve rectification work that is not captured on the DVSA system, meaning the underlying mechanical concerns are not visible in the official record. The trend therefore shows a vehicle struggling to retain roadworthy status on first attempt, which warrants a particularly thorough pre-purchase inspection. Recorded mileage of 128,875 miles over approximately 18 years equates to an annual accumulation of roughly 7,160 miles, a figure broadly in line with typical usage for a vehicle of this vintage. There are no significant gaps in the testing record within the last five years, suggesting the car has been in regular use rather than laid up for extended periods, which reduces the likelihood of dormant issues such as seized brake callipers, perished cooling system hoses, or degraded petrol. The relatively consistent annual mileage also implies normal wear rates for consumables, and a buyer should therefore expect age-related degradation on suspension components, brake discs and pads, and exhaust mounting rubbers proportional to this level of use. Given the absence of specific advisories in the recorded MOT data, a hands-on evaluation becomes essential to identify the latent issues that have caused the repeated failures. On a test drive, pay close attention to the C5's hydropneumatic suspension, if fitted, listening for any harshness over bumps, uneven ride height, or warning messages on the instrument cluster, as the self-levelling spheres and hydraulic struts are known wear items that can produce a harsh impact when depleted of pressure. Check for knocking or clonking from the front suspension over uneven surfaces, particularly from lower wishbone bushes and anti-roll bar drop links, and listen for any creaking from the rear axle assemblies during low-speed manoeuvres. The steering should feel precise without any vagueness or delay, as worn suspension linkages on these vehicles can introduce slop that only becomes apparent during directional changes. Brake evaluation should focus on pedal feel and stopping response, with the pedal inspected for any sponginess or excessive travel that could indicate hydraulic issues within the system's sealing components. On a straight road, apply light and heavy braking to detect any judder through the pedal, which would suggest warped front discs, and listen for any grinding noises that might point to worn pads contacting the disc surface. The engine bay should be inspected for any signs of fluid leaks from power steering or hydraulic suspension accumulators, oil seepage around the cam cover or sump gasket, and the condition of all visible brake pipes and fuel lines for any surface corrosion, particularly along the underbody where road salt exposure is most aggressive. Finally, request that any rectification work from the recent failures be evidenced with invoices, as understanding what was actually replaced or repaired will be critical to judging the current mechanical state of this 18-year-old Citroen.
