2018 Citroen C3 Aircross 1.2L Petrol · DL67 DFJ

The defining mechanical story for this 2018 Citroen C3 Aircross centres on the brake system and rear tyre condition. Across seven recorded MOT tests, only one failure is present, dated 2023-07-05, classed as Dangerous due to an Offside Rear Tyre with ply or cords exposed through perished and split rubber, accompanied by advisories for the nearside rear tyre wearing close to the legal limit with perishing in the tread and outer wall, plus a thorn in the offside front tyre. The remaining six tests all resulted in passes, with the most recent on 2026-06-25 showing no defects recorded and the prior 2025 test also entirely clean. However, the 2024 test carried five advisories simultaneously, four for brake pads wearing thin at both front and rear axles and one for a nearside front brake disc showing pitting or scoring. This cluster suggests a period of brake wear that was monitored but not replaced before test, and a buyer should treat the braking components as the primary area requiring immediate inspection and likely expenditure. With a recorded mileage of 72,390 miles over approximately eight years, annual accumulation averages around 9,000 miles, broadly typical for a vehicle of this age. The testing record shows consistent annual visits from 2020 onwards with no multi-year gaps that would suggest extended periods off the road, which would otherwise raise concerns about stale brake fluid, seized calipers, or perished rubber components. The relatively uniform annual mileage points to regular use, which generally keeps consumables rotating and prevents the kind of deterioration associated with long-standing vehicles. That said, higher-mileage examples of this generation C3 Aircross commonly show wear in suspension components, clutch assemblies, and turbo-related items where fitted, none of which appear in the MOT record because they are not assessed at test, so mileage remains the primary indicator for those mechanical areas. Given the 2024 brake advisories and the 2023 dangerous tyre failure, a prospective buyer should focus their pre-purchase inspection on the braking system. Check the current thickness of all four brake pads, as those flagged as wearing thin two years ago will almost certainly now require replacement, and inspect the nearside front brake disc for visible lipping, ridges, or hot spots indicating it has reached its minimum thickness and needs renewing alongside the pads. On test drive, listen for any scraping or grinding from the calipers, watch for pulling to one side under braking which would indicate a binding caliper or uneven pad deposition, and feel for vibration or judder through the pedal that suggests disc runout. Inspect all four tyres carefully for cracking, bulging, or uneven wear, particularly on the rear axle given the perishing and exposed ply noted in 2023, and verify the sidewall date codes to confirm they are within a sensible age range. Beyond the brakes and tyres, the test drive should pay attention to the suspension and steering, as these areas are not specifically flagged but are common wear points on a C3 Aircross approaching 73,000 miles. Listen for clonking or knocking over uneven surfaces, which often points to worn anti-roll bar links, drop links, or front strut top mounts typical of this platform. Check for steering wander or excess play, which can indicate worn tie rod ends or rear axle bush deterioration. With the engine, allow a cold start if possible and watch for excessive smoke, listen for timing chain rattle on initial startup, and confirm the cooling fan operation. Finally, inspect the underside for any oil leaks from the engine or gearbox, and examine the rear axle beam and subframe mounting points for corrosion, as road salt exposure over eight winters can initiate rust in structural areas even when not yet flagged at MOT.
