2020 Citroen C5 1.5L Diesel · DY70 LSO

The defining mechanical story for this 2020 Citroën C5 is a generally clean roadworthiness record punctuated by a couple of presentation and consumable failures rather than any structural or systemic deterioration. Across four annual tests from 2023 to 2025, the vehicle passed three times with no defects recorded, while two failures stand out and are worth examining in context. The 2023 failure was driven by two Dangerous defects relating to both front tyres having tread depth below the legal 1.6mm limit, alongside a minor registration plate lamp issue. The 2024 failure was narrower, caused by both registration plate lamps being inoperative and classed as Major defects rather than the previous year's Minor classification, but the vehicle subsequently passed a retest on the same day with no defects recorded. The most recent test on 3 November 2025 produced a pass, but with two advisories that signal the rear braking system is now beginning to wear and merit attention before the next MOT. There are no advisories relating to corrosion, suspension components, exhaust integrity, steering, or structural areas, which is a positive indicator for a vehicle of this age approaching six years old. Mileage recorded at the most recent test stands at 46,680 miles, which equates to roughly 7,780 miles per year over the vehicle's lifetime, broadly in line with typical usage for a car of this age. The annual accumulation is unremarkable and there are no large gaps between tests that would suggest extended periods off the road, nor any sudden jumps in mileage between consecutive tests that might indicate clocking or irregular use. The relatively modest annual mileage means wear on major drivetrain components should be proportionate to distance covered rather than age, which is favourable, but it does mean consumables such as brake pads, discs, tyres, and ageing rubber components may deteriorate through time as well as through use. The pattern of annual testing from November 2023 through to November 2025 is consistent, giving a continuous picture of the vehicle's mechanical state. For a prospective buyer, the rear braking system flagged at the 2025 test should be the primary area of mechanical focus. Both rear brake pads were noted as wearing thin and both rear brake discs were recorded as worn, pitted, or scored. On a test drive, listen for any grinding or metallic squeal from the rear brakes under light application, and check for vibration through the pedal under firm braking which could indicate disc run-out or uneven wear. Inspect the rear discs visually for a pronounced lip at the outer edge and any visible scoring or rust pitting across the braking surface, as pitted discs that are nearing their wear limit will usually require replacement rather than just refacing. The front pads and discs have not been flagged at recent tests, so verify that the front calipers are not binding by checking for wheel hot spots after a short drive, and confirm the brake fluid has been changed in line with manufacturer intervals as this is not visible from MOT records but is a known maintenance item on vehicles of this age. The tyre failures from November 2023 should also inform a pre-purchase inspection, even though they are now historical. Both front tyres were at or below the legal 1.6mm minimum, suggesting the previous tyres may have been run close to or beyond their serviceable life. Check the current tyres for age-related sidewall cracking, uneven shoulder wear which can point to suspension or geometry issues, and ensure the tread depth is comfortably above the legal limit with no flat spots from standing. The registration plate lamp failures across two consecutive years, escalating from a Minor to Major classification, are typically trivial electrical issues such as failed bulb elements or corroded lamp holders, but confirm both lamps illuminate correctly at inspection and that the wiring and earth connections are sound. Beyond these specific flagged items, listen on the test drive for any clonks or rattles from the front suspension over uneven surfaces, check for steering pull or vibration, and inspect the underside for any signs of fluid leaks, corroded brake lines, or exhaust deterioration which would be consistent with a UK-registered vehicle approaching its seventh year.
