2011 Citroen C1 1.0L Petrol · NJ11 YTH

The vehicle holds a current roadworthiness certificate following the October 2025 test at 119,922 miles, though the maintenance trend indicates deteriorating mechanical condition. While the tester passed the vehicle, the most recent test flagged a worn offside front suspension arm pin or bush alongside both front tyres wearing close to the legal limit. This points to ongoing suspension degradation rather than a one-off issue, particularly when cross-referenced with the recurring front anti-roll bar pin or bush wear noted in October 2023. The persistent blue smoke from the exhaust during acceleration, flagged as an advisory in 2023, suggests an unresolved engine issue that demands immediate attention. Accumulating 119,922 miles over a 15-year lifespan equates to roughly 8,000 miles annually, a typical figure for urban or short-trip usage. The MOT records demonstrate remarkably consistent yearly increments, covering 9,296 miles between October 2023 and October 2024, and a further 9,076 miles by October 2025. There are no significant gaps in the mileage trajectory to suggest the vehicle stood idle for extended periods, confirming regular, albeit light, annual use. This steady accumulation means the mechanical components have endured consistent wear rather than the severe corrosion often caused by long-term standing. A physical inspection must prioritise the front suspension and braking components given the recurring defects. The repeated advisories regarding the front anti-roll bar and suspension arm bushes point to a pattern of wear that likely affects wheel alignment, evidenced by the edge wear on the front tyres noted in the 2025 test. Check the condition of the rear brake pipes closely; the tester flagged excessive corrosion and grease contamination on the nearside and offside rear lines during the 2023 failure, which may have been patched rather than properly replaced. The blue exhaust smoke during acceleration indicates oil combustion, possibly from worn valve stem seals or piston ring wear, a condition that will worsen without intervention. Finally, verify the operation of the front position lamps, as both units failed on the 2024 test, suggesting an underlying wiring or earth fault rather than simple bulb failure.
