2006 Citroen C1 1.0L Petrol · LR06 OYK

A recurring theme across the MOT history of this 2006 Citroen C1 is its near-side rear brake assembly, which has attracted advisory and failure attention in multiple years and presents the single clearest mechanical risk in the record. On the most recent test dated 21 June 2025 the vehicle passed with an advisory noting that the offside rear service brake was binding, though not excessively, and the same near-side rear corner was the subject of three major failures at the previous attempt on 21 June 2021, when the service brake was recorded as excessively binding and excessively fluctuating, and the parking brake was inoperative on that side. Brakes at the rear of C1 models are typically drum units which are prone to seizing of the wheel cylinder or the handbrake mechanism, and the 2025 advisory suggests residual symptoms that have not yet progressed to a failure. Headlamp lens degradation has also been flagged at every test since 2022, with both front lamps described as having a product on the lens that does not yet seriously reduce light output, indicating progressive oxidisation of the polycarbonate. Lighting defects were the only failures on the 21 June 2024 retest, with an inoperative registration plate lamp and an offside rear stop lamp adversely affected by another lamp, both relatively minor electrical items that were presumably rectified before the same-day pass. The recorded mileage of 98,672 miles over approximately 20 years equates to an annual accumulation of roughly 4,934 miles, which is notably low for a vehicle of this age and suggests either periods of light use or extended standing between journeys. The testing cadence has been annual since at least 2020, with no unusually long gaps in MOT cover, indicating that the vehicle has generally remained on the road and in regular testing rather than being laid up for prolonged periods. Despite the low average mileage, the advisory pattern demonstrates that age-related wear of consumable components such as tyres, brake pads, brake discs and rubber seals is still progressing, which is typical of a car of this vintage. Mileage figures appear broadly consistent across the recorded tests rather than showing sudden jumps, which is consistent with steady light use. A prospective buyer should pay particular attention to the near-side rear brake during a test drive, listening for scraping or dragging sounds from that corner when the handbrake is released and feeling for any pulling, uneven retardation or a handbrake that fails to hold the car on an incline, as the repeated binding and fluctuating readings on that wheel strongly indicate a seized adjuster, sticky wheel cylinder or distorted drum. Both front tyres have been flagged repeatedly for inner-edge wear, with baldness noted in 2020 and 2021, and this warrants inspection of the front suspension geometry, particularly the condition of the track rod ends, lower arms, suspension bushes and any visible corrosion on the front subframe mounting points, as well as checking for uneven tyre wear across the axles. Front brake discs have been noted as pitted or scored since 2023 and pads were flagged as wearing thin through 2021, 2022 and 2023, so a residual brake pedal judder or vibration under firm braking would corroborate that the discs are now at or near replacement thickness. The headlamp lens hazing is worth polishing or restoring before the next test, and a walkaround should also look closely at the rear tyres, which were recorded as perished and slightly damaged in 2025 and may now be due for replacement given their age. Finally, the recurring inoperative registration plate and stop lamp issues warrant a simple check of all rear lamp bulbs and their earth connections to confirm the wiring has been properly remediated since the 2024 retest.
