2022 Dacia Duster 1.0L Petrol · CK72 AAZ

The Dacia Duster in question presents a clean but puzzling MOT record, with the most recent test on 18 August 2025 at 20,004 miles passing without defects, immediately preceded by a failed test just five days earlier at 19,945 miles—also with no faults recorded. This inconsistency suggests a procedural error rather than a mechanical issue, as the vehicle cleared inspection with no advisories or defects on both occasions. The absence of recurring advisories or failures across critical systems—such as brakes, suspension, emissions, or structural integrity—implies no obvious signs of neglect or deteriorating reliability. That said, the failure itself raises questions about testing accuracy, particularly given the lack of mileage progression between tests, which is highly unusual. Without further context, the vehicle’s roadworthiness appears stable, but the anomaly demands clarification from the seller. The mileage of 20,004 miles over four years—roughly 5,000 miles annually—is exceptionally low for a vehicle of this age and type, typically indicating either very light use or prolonged periods of inactivity. The near-identical mileage between the failed and passed MOTs (a mere 59-mile difference over five days) further suggests the car may have sat unused for extended periods, possibly between tests. Such low annual mileage can lead to other issues, such as seized components from lack of movement or degraded fluids from infrequent operation. Buyers should verify whether the vehicle has been driven regularly or stored, as this could influence long-term reliability, particularly in areas like battery health, fuel system condition, and tyre wear. Given the lack of defects in the MOT history, no specific mechanical components stand out as high-risk priorities for immediate inspection. However, the buyer should still verify a few key areas in person. The brakes—particularly the rear calipers—should be checked for binding or uneven wear, as this was a common issue in earlier Duster models and could explain the failed test if overlooked. Suspension components, including coil springs and bushings, should be assessed for corrosion or excessive wear, especially if the vehicle has spent time in damp conditions. Structural integrity, particularly around wheel arches and sills, should be scrutinised for early signs of corrosion, given the Duster’s susceptibility in certain regions. Finally, while the MOT record is clean, the unusual testing discrepancy means a thorough pre-purchase inspection by a qualified mechanic is advisable to confirm no underlying issues were missed.
