2007 Citroen C4 2.0L Diesel · WU07 AEK

The most recent DVSA examination on 18 August 2025 recorded a straightforward pass with no advisories or defects, which is a positive indicator of the vehicle's current roadworthiness. However, evaluating the broader test history reveals a pattern that warrants attention. The 2024 entry shows a failure on both headlamp aim projections, an issue subsequently rectified before the same month's retest. More significantly, the 2023 advisory notice flagged wear and corrosion on both nearside and offside front inner suspension arm pins or bushes, alongside sills showing cosmetic corrosion. While these were noted as not affecting structural strength, braking, or steering at the time, suspension components of this nature typically progress with continued mileage and age, so they should not be overlooked. The 2022 advisory regarding excessive exhaust smoke suggests possible turbo or internal engine wear consistent with a high-mileage diesel or petrol unit. Overall, the trend is relatively stable rather than worsening, though the accumulating advisories indicate a vehicle requiring incrementally more maintenance attention rather than one in peak mechanical condition. With recorded mileage of 156,684 against a 19-year vehicle age, this C4 is averaging approximately 8,247 miles annually, which sits broadly within typical parameters for its cohort. That said, the cumulative figure represents substantial mechanical wear, particularly across engine internals, transmission, clutch, suspension, and braking consumables. There are no obvious extended gaps in the annual MOT record, suggesting the vehicle has been in consistent use rather than left standing for prolonged periods, which generally helps preserve drivetrain seals and prevent severe brake disc corrosion. Nevertheless, at this mileage threshold on a PSA-derived platform, components such as timing chains (where applicable), dual-mass flywheels, turbochargers, injectors, and suspension subframes commonly approach end-of-service life, regardless of how gently the car was driven. Given the front suspension advisories recorded in 2023, a prospective buyer should conduct a focused physical inspection and test drive evaluation. Listen for clonks, knocks, or rattles emanating from the front suspension over speed bumps, uneven road surfaces, and during full-lock manoeuvres, as worn lower arm bushes will produce a distinctive dull thud or creak. Examine the inner and outer sills for any progression beyond the previously noted cosmetic corrosion, particularly checking the structural members and jacking points for perforation. On the test drive, verify straight-line stability, absence of steering wander, and even tyre wear across both front and rear axles, because uneven camber wear often points to the very bushes previously flagged. Inspect the exhaust system for blue or excessive grey smoke on startup and under acceleration, as the 2022 advisory may indicate oil consumption or turbo seal deterioration that could have progressed in the intervening period. Additionally, check for fluid leaks beneath the engine and gearbox after a run, and confirm the cooling system functions correctly given the mileage. Beyond the items directly highlighted by the MOT history, several age and mileage-related considerations deserve attention before purchase. Tyres should be examined for both tread depth and sidewall perishing, as rubber compounds degrade with age regardless of remaining tread, and a 19-year-old car may still be fitted with aged rubber that compromises grip. The 12-volt battery is unlikely to be original and should be load-tested, with the battery tray and surrounding wiring checked for corrosion. Brake discs and pads should be physically inspected for wear margin and disc lipping, and the caliper slide pins examined for seizure, particularly on a vehicle of this age. Brake fluid, coolant, and if applicable automatic transmission fluid should be replaced on a calendar basis rather than purely by mileage, given the vehicle's age, so verify service records for these time-sensitive interventions. Finally, inspect the headlamp units themselves, as the recent failure suggests either adjustment drift, unit degradation, or possible damage to the projector lens, all of which can be remedied relatively inexpensively but should be confirmed resolved before purchase.
