2017 Citroen C1 1.0L Petrol · FD17 MPZ

The most recent MOT on 23 June 2026 resulted in a failure because the off‑side front position lamp was not operational, and it was accompanied by several advisories – notably a fluctuating off‑side front service brake and early signs of perishing on both rear tyres. While the vehicle passed its MOTs in 2020, 2021 and 2022 without defects, a pattern of emerging issues has appeared from 2022 onward, indicating a gradual decline in condition rather than an improvement. The recurring tyre and brake advisories suggest that wear is now becoming a factor and that attention will be required to bring the car back to a fully compliant state. At nine years old the recorded 41,310 miles equates to roughly 4,600 miles per annum, which is well below the typical UK average for a vehicle of this age. Such low utilisation often points to periods of limited use or extended storage, which can be as detrimental as high mileage because rubber compounds, seals and battery plates age regardless of distance travelled. The modest annual mileage reduces the likelihood of excessive mechanical wear on the drivetrain, but it also raises the risk of tyre sidewall cracking, brake disc corrosion and fluid degradation that are time‑related rather than mileage‑related. Prospective buyers should give particular attention to the rear tyre condition; the advisories flag slight damage and cracking that can progress rapidly to tread loss or a sudden blow‑out, especially if the tyres have been standing for long periods. Inspect the sidewalls for dry rot, bulges or exposed cords, and verify the tyre age via the DOT code – any tyre older than six years should be considered for replacement regardless of tread depth. The fluctuating off‑side front service brake, together with the advisory about thin inner pads and pitted discs, warrants a thorough brake inspection: feel for any pedal pulsation, listen for uneven squealing, and check that the ABS sensor wiring is intact. If the pads are indeed near the wear limit, a replacement of the pads and a resurfacing or fitting of new discs will be required to restore consistent braking performance and to eliminate the MOT advisory. Beyond the immediate defects, confirm that the off‑side front position lamp is fitted and functional, and verify the operation of all other exterior lamps and signal lights. Examine the battery terminals for corrosion and have the 12 V battery load‑tested, as a vehicle that sits idle for extended periods often suffers reduced capacity. Check the condition of the suspension bushes, coil springs and anti‑roll bar links for any signs of cracking, oil leakage or excessive play, which can manifest as clunking noises over bumps. Finally, assess the condition of engine oil, coolant and brake fluid – all of which degrade with age – and ensure that a full service has been recorded in the service book, or be prepared to undertake a comprehensive fluid change and filter replacement as part of the next maintenance cycle.
