2019 Dacia Duster 1.5L Diesel · SE68 JFF

The Dacia Duster’s most recent MOT history reveals a concerning pattern of repeated failures despite no recorded defects on either test. The vehicle failed twice in March 2026—first on the 5th at 66,540 miles, then passed on the 12th at the same mileage—before passing again in April 2025 and March 2024 without incident. This inconsistency suggests either a technical oversight during the retest or a genuine but intermittent issue that evaded detection on the initial inspection. The absence of specific defect codes in the failed tests complicates diagnosis, but the repeated retesting at the same mileage implies the tester suspected a latent problem, possibly related to emissions, suspension alignment, or brake binding that only manifested under specific conditions. The recorded mileage of 66,540 miles over seven years aligns with typical usage for this model, averaging around 9,500 miles annually. However, the gap between the 2024 and 2025 tests—covering 11,226 miles—is unusually long for a vehicle that has otherwise passed without fail. This suggests either a period of reduced usage or a deliberate deferral of maintenance. The identical mileage on the 2026 failures (66,540) also raises suspicion of mileage tampering, though this cannot be confirmed without further evidence. If the vehicle was genuinely driven at this rate, the suspension components—particularly the rear bushes and coil springs—should be scrutinised for wear, as should the brake calipers and discs for uneven wear patterns or binding. Given the lack of specific defect details, a buyer should prioritise an independent inspection of the suspension geometry, as repeated failures often point to alignment or bush deterioration. The brakes warrant close examination for inconsistent pad thickness or warped discs, particularly if the tester suspected binding. Corrosion in wheel arches, subframe, or sills is another critical area, especially given the vehicle’s age and exposure history. The engine bay should be checked for oil leaks or degraded hoses, while the exhaust system must be inspected for rust-through or loose mounts, as these are common failure points in this model. The 2026 retest suggests a need for thorough diagnostics, so any buyer should demand a full service history or evidence of recent mechanical checks beyond the MOT.
