2015 Citroen C4 1.6L Diesel · LB15 XRY

The defining mechanical story of this 2015 Citroen C4 centres on a braking system that has progressively drawn attention over the last four years, combined with a single lighting and wiper-related failure that was rectified at the same test. The most recent MOT on 16 September 2025 recorded a pass, but with an advisory that both front tyres were worn close to the legal limit and worn on the edge, suggesting uneven wear geometry worth investigating. Looking back, the 2024 test was entirely clean, while the 2023 test was also passed without advisories. The earlier 2022 record is where the braking concerns first surfaced, with advisories logged for both front brake discs being pitted or scored on the same visit, plus a nearside rear brake pad advisory. That same day, the vehicle failed on a headlamp aim issue too low and a defective front wiper blade, both relatively minor items but indicating that the lighting alignment and wiper condition had been allowed to deteriorate. The fact that the same pitted discs were noted on both the pass and failure entries on the same date confirms the brake condition was already borderline at that point. With 89,557 miles recorded across approximately eleven years, this C4 is averaging around 8,142 miles annually, which sits comfortably within the typical range for a car of its age and keeps it squarely in the expected wear band rather than the low-mileage or high-mileage extremes. There are no unusual gaps between tests, with annual MOT entries consistently recorded from 2022 through to 2025, which suggests the vehicle has remained in regular use throughout this period rather than being laid up for any extended stretch. From a mechanical standpoint, this kind of steady, moderate accumulation rate generally translates to predictable wear on consumables such as brake pads, discs, tyres, and suspension components, with the cumulative mileage being sufficient for wear items to have been replaced multiple times but not so high that major drivetrain components such as the clutch or automatic transmission would necessarily be at end-of-life. Given the recurring front brake disc advisories from 2022 and the front tyre edge wear noted most recently, a prospective buyer should focus attention on the braking system, suspension geometry, and steering components during a physical inspection. The fact that both front discs were recorded as pitted or scored suggests possible sticking calipers or worn guide pins, so on a test drive listen for any grinding or pulsing under braking, feel for judder through the pedal, and check whether the vehicle pulls to one side under firm stops. The 2025 advisory regarding both front tyres worn close to the legal limit and worn on the edge points towards possible camber or tracking issues, possibly from worn suspension bushes, droplinks, or strut top mounts, so pay particular attention to any knocking from the front end over speed bumps, vague steering, or uneven tyre wear patterns across the axle. The 2022 headlamp aim failure should also prompt a check that both headlights are correctly aligned, as misadjustment can recur if the mounting brackets have worn, and ensure the wiper blades and washer jets are functioning correctly with no smearing across the windscreen. Finally, given the mileage, it would be prudent to inspect the rear brake pads and discs, exhaust system for corrosion at the mounting points, and check for any oil leaks from the engine and gearbox seals which become more common at this mileage bracket.
