2009 Citroen C4 1.6L Diesel · EX59 WGP

Recurring steering and suspension issues define the mechanical profile of this Citroen C4, with steering rack components and shock absorber bushes appearing repeatedly across several testing cycles. The most recent test on 16 September 2025 resulted in a pass, but only after a failure regarding headlamp aim, and it left the vehicle with ongoing advisories for offside play in the steering rack inner joints and worn bushes on both rear lower shock absorbers. This pattern suggests that while immediate failures are being addressed, the steering system and rear suspension assembly are subject to progressive wear that has persisted through the 2024 and 2025 testing periods. The vehicle has covered 113,368 miles over its approximately 17-year lifespan, which equates to an average annual usage of roughly 6,669 miles. This represents a relatively low annual mileage for a vehicle of this age, which can often mean that components like rubber bushes, tyres, and seals are subject to age-related degradation and perishing rather than purely mileage-based wear. This is evidenced by the 2024 advisories regarding cracking or perishing on the nearside and offside front tyres, as well as the recurring issues with rubber gaiters and boots noted in previous years. A prospective buyer should pay close attention to the steering and front-end geometry during a test drive. Given the documented history of play in the steering rack inner joints and track rod ends, listen for any clicking or knocking sounds when turning the steering wheel at low speeds or when navigating uneven surfaces. Any wandering sensation or a tendency for the vehicle to pull to one side could indicate that the steering rack or associated linkages require further attention. The recurring advisories for steering rack gaiters and drive shaft CV boots also suggest that the integrity of these protective components is a critical area to inspect to prevent premature failure of the joints themselves. The rear suspension and braking systems also require scrutiny. The presence of worn bushes on both rear lower shock absorbers may manifest as thumping or knocking noises from the rear of the car when driving over bumps or speed humps. Additionally, while the 2023 failure for dangerously thin rear brake pads was recorded, the 2022 advisory for wearing thin pads indicates a trend in brake component depletion. During a test drive, check for any grinding noises during braking or any vibration through the pedal, which could indicate uneven wear or issues with the brake discs and calipers.
