2021 Dacia Duster 1.3L Petrol · AX21 DWD

The 2021 Dacia Duster’s latest MOT test on 2026-06-23 resulted in a clean pass, with no failures and only minor defects—specifically, a non-critical windscreen damage that did not impair the driver’s field of vision. The advisory items, however, reveal a persistent issue with the near- and offside rear tyres showing signs of cracking or perishing, which the DVSA has flagged in two consecutive MOTs (2025-06-18 and 2026-06-23). This recurring advisory suggests a pattern of tyre degradation that, while not failing the MOT, indicates potential long-term vulnerability to reduced tyre life and compromised road grip, particularly in wet or adverse conditions. The absence of failures in the most recent test does not negate the need for proactive management of these advisories, as tyre perishing can accelerate uneven wear or sudden blowouts, posing a safety risk. The recorded mileage of 30,011 miles for a vehicle aged five years represents a moderate annual usage rate of approximately 6,002 miles per year, which is within the expected range for this model’s age and typical UK driving conditions. Such mileage does not inherently suggest excessive wear, but it does imply consistent use over time, which can accelerate consumable degradation—particularly in suspension components, brake systems, and fluid integrity. The lack of significant mileage gaps or rapid accumulation does not indicate neglect, but it also means that wear patterns may be developing gradually rather than abruptly. For instance, the suspension bushes and coil springs could show signs of fatigue or stiffness if not replaced at recommended intervals, while brake discs and pads may exhibit signs of thinning or corrosion if the vehicle has spent prolonged periods stationary. As a prospective buyer, the most critical inspection focus should be on the rear tyres, given the repeated DVSA advisories. The cracking or perishing observed in the MOT tests suggests the tyres may have reached or exceeded their useful life, especially if they have been in service for several years. Visually inspect the tyre tread and sidewall for any signs of delamination, dry rot, or exposed fibres, and check for uneven wear patterns that could indicate misalignment or suspension issues. On a test drive, listen for unusual noises from the rear axle or suspension, such as clunks or rattles, which may signal worn suspension components or loose wheel bearings. If the tyres are beyond their safe operational life, they should be replaced immediately to prevent a blowout or hydroplaning hazard. Beyond the tyres, the Dacia Duster’s age and usage profile warrant a thorough examination of other critical systems. Given the vehicle’s moderate mileage, check the condition of the 12V battery, ensuring it holds a charge and has no signs of corrosion or fluid leaks around the terminals. The brake system should be inspected for corrosion on the discs, particularly if the vehicle has been stationary for extended periods, as this can lead to binding calipers or reduced braking efficiency. Additionally, verify the condition of the coolant, oil, and transmission fluid, as these fluids degrade over time and should be replaced at the manufacturer’s recommended intervals—typically every 60,000 to 100,000 miles or every two to three years, depending on the fluid type. Lastly, examine the exhaust system for leaks or corrosion, as emissions-related advisories or failures could become a recurring issue if not addressed. A comprehensive pre-purchase inspection by a qualified mechanic would be advisable to confirm the absence of hidden mechanical issues, such as drivetrain wear or structural fatigue, which may not be apparent in routine visual checks.
