2021 Citroen C3 Aircross Shine Puretech S/S 1.2L Petrol · SO21 JMX

A pattern of brake component wear and a single TPMS-related failure define the mechanical story of this 2021 Citroen C3 Aircross. Across three MOT test dates, the front brake discs and pads were flagged in 2024 as wearing, followed a year later by advisories on both rear brake discs and rear pads, indicating that consumable friction components have been progressively approaching replacement. A failure was recorded on 2026-07-22 for a malfunctioning or inoperative Tyre Pressure Monitoring System, though the vehicle was refiled as a pass on the same date, suggesting the defect was rectified during the same inspection visit. The absence of any structural, corrosion, suspension, or lighting advisories across the recorded tests indicates no broader systemic issues have been flagged by the testing station, with attention centred on routine wear items. Mileage accumulation of 33,368 miles over approximately five years equates to around 6,674 miles annually, which is broadly typical for a vehicle of this age and segment. Testing cadence is consistent, with annual entries in 2024, 2025, and 2026, and no extended gaps that would suggest the vehicle was off the road for prolonged periods. This steady, moderate usage pattern is consistent with regular urban or commuter use, placing predictable demands on braking components, tyres, and suspension rather than the accelerated wear associated with very high annual mileage. The records do not indicate any unusual mileage jumps or omissions between tests. For a prospective buyer, the priority inspection areas are the braking system and the TPMS. The 2024 advisories on front discs and pads, followed by 2025 advisories on both rear discs and pads, suggest that all four corners may now be approaching or at the point of requiring disc and pad replacement. On a test drive, listen for any grinding, squealing, or pulsation through the brake pedal, particularly under firm application, and inspect the visible pad thickness through the wheel spokes if possible. Given the rear discs were specifically noted as pitted or scored, check for any judder or vibration when braking at speed, which can indicate disc runout or uneven wear surfaces. The nearside front should also be checked carefully, as it was the first to attract attention in 2024. The TPMS failure warrants verification that the system is currently operating correctly; a warning light should illuminate briefly on ignition and then extinguish, and any persistent illumination should be queried with the seller. The 2026 advisory noting a non-excessive oil leak from the sump plug area should be inspected visually for fresh seepage around the sump plug and adjacent gasket surfaces, and the oil level should be checked on the dipstick before purchase. Additionally, the engine should be started from cold during the viewing to listen for any timing chain rattle characteristic of the PureTech petrol units, and a thorough under-bonnet check for oil residue on the cam cover and breather system is advisable given the powertrain fitted. A scan for any stored TPMS sensor fault codes would also be prudent to confirm the repair is complete and not reliant on a temporary reset.
