2017 Citroen C4 1.6L Diesel · FN17 XHT

The most recent DVSA examination on 5 August 2026 resulted in a Pass, but it is notable that this test was conducted only one day after a previous attempt on 4 August 2026 which recorded two Dangerous defects relating to the braking system. The vehicle was therefore refused certification on safety grounds before being re-presented in a satisfactory condition the following day. While the current Pass is a positive outcome, the advisories recorded on both occasions are relevant: an oil leak, though not yet excessive, and wear to a front suspension arm pin or bush. The 2024 test cycle also showed a period of deterioration, with Major defects recorded for a headlamp, registration plate lamp, and windscreen washer before those items were rectified and a clean certificate issued in April 2025. Overall, the maintenance trend appears broadly stable but with a recent uptick in mechanical defects and tyre condition issues, suggesting that a prospective buyer should not assume the vehicle has been consistently well maintained merely on the strength of the latest Pass. With recorded mileage of 147,442 against an age of approximately nine years, this Citroen C4 has covered around 16,382 miles annually, which is substantially higher than the average for its cohort. The MOT records do not show any significant gaps in testing, and mileage progression appears relatively consistent, indicating a working or high-use vehicle rather than one that has been laid up for extended periods. High annual mileage of this nature accelerates wear on all major mechanical systems including the clutch, turbocharger if fitted, engine internals, gearbox mountings, suspension components, and braking hardware. The cumulative effect of sustained heavy use is most evident in consumable items, and the recent brake failure underlines how rapidly pads can be worn down when the vehicle is in frequent service. The gearbox, dual mass flywheel if applicable, and exhaust system are areas where impending attention should be anticipated. The Dangerous brake pad defects recorded on the 4 August 2026 test, both front and rear, indicate that friction material had worn below the minimum legal thickness of 1.5 mm. At this level braking efficiency is severely compromised, with symptoms such as extended stopping distances, a soft or low pedal, and in severe cases the metal backing plate making contact with the brake disc which causes scoring, vibration, or a grinding noise. On inspection, verify the thickness of all four brake pads and check the brake discs for ridging, lipping, or scoring which would necessitate replacement rather than simply a pad change. Inspect the calipers for any signs of binding or seized pistons which can cause uneven pad wear and pulling under braking. The suspension bush advisory on the nearside front should be assessed for any play or knocking under load; symptoms include a clonking noise from the front when traversing speed humps or uneven surfaces and vague, imprecise steering. It is also worth checking the rear brake shoes and handbrake mechanism if applicable, as these are not always thoroughly inspected during routine servicing. The advisories relating to oil leaks suggest checking the engine and gearbox for residue or weeping around the sump, camcover, and turbo oil feed lines if fitted; listen for any change in engine note or bearing rumble that might indicate oil pressure issues. Tyre condition has been a recurring concern, with cracking and perishing flagged on the offside front and rear items. At nine years old, even tyres with adequate tread depth can suffer from sidewall perishing caused by UV exposure and age, which is not always visible at a glance. Closely inspect the sidewalls for hairline cracks and check the production DOT date code; tyres older than six years should be regarded as nearing the end of their safe service life regardless of tread remaining. Beyond the MOT record, given the high mileage, verify the timing belt or chain replacement interval has been observed according to manufacturer schedule, confirm recent servicing stamps in the book, and ensure that brake fluid, coolant, and gearbox oil have been changed at calendar-appropriate intervals rather than only on mileage triggers. A 12V battery health check is also worthwhile as the original unit will be long past its expected service life, and a failing battery can cause erratic electrical behaviour which may explain some of the lighting faults seen in the 2024 tests.
