2021 Dacia Duster 1.5L Diesel · RT07 DOG

The 2021 Dacia Duster’s latest DVSA MOT test on 2025-11-20 resulted in a passing grade, though it included two advisories related to front brake components. The previous MOT in 2024-11-20 was entirely clean, indicating no prior failures or major defects. While the advisories from 2025 suggest a recurring trend of brake wear—specifically thin front inner brake pads and a worn but not excessively thin front brake disc—the absence of failures in the intervening year suggests this is a maintenance issue rather than a developing mechanical problem. The consistency between the two advisory tests implies a stable wear pattern, likely due to regular driving habits or scheduled servicing, rather than a sudden deterioration. However, the advisories do warrant attention, as they indicate that the brake system is approaching or has reached a state where further wear could compromise stopping performance if not addressed promptly. The recorded mileage of 24,947 miles for a vehicle aged five years represents an annual usage rate of approximately 4,989 miles, which is notably lower than the typical wear rates expected for a vehicle of this age and class. Lower mileage can stem from infrequent use, prolonged periods of stationary storage, or a more cautious driving style, all of which may have contributed to reduced wear on consumables like brakes, tyres, and suspension components. However, it is also possible that the vehicle has been driven sparingly due to mechanical concerns or a lack of necessity, which could have delayed necessary maintenance. The low annual mileage does not inherently indicate better mechanical condition, as standing vehicles can suffer from issues such as corrosion to brake components, suspension bushes, and exhaust systems, or fluid degradation from stagnation. Conversely, if the vehicle has been driven regularly but with lower-than-expected mileage due to factors like fuel economy or route planning, the wear profile may still be within acceptable limits. Given the advisories on front brake pads and discs, the prospective buyer should conduct a thorough inspection of the braking system during a test drive. Listen for any unusual noises such as grinding, squeaking, or a pulsating feel through the pedal, which could indicate worn pads, warped discs, or binding calipers. Visually inspect the front brake discs for uneven wear, cracks, or corrosion, and check the brake pads for residual thickness—if they are below 1.5mm, replacement is strongly advised. Additionally, verify that the brake fluid level is adequate and that there are no leaks around the brake lines or master cylinder. The advisories suggest that the pads are nearing the end of their service life, and the discs are worn but not yet critically thin, so maintenance should be scheduled within the next 1,000 to 1,500 miles to prevent further wear and potential failure. Beyond the brake system, the buyer should also address the broader implications of the vehicle’s low annual mileage and age. Inspect the tyres for signs of sidewall cracking or perishing, which can occur even with low mileage if the vehicle has been stored for extended periods without rotation or rotation. Check the tyre tread depth for uniformity and signs of uneven wear, which could indicate suspension or alignment issues. Given the vehicle’s age, the 12V battery should be tested for health, as older batteries may struggle with cold starts or fail entirely if not maintained. Fluid levels, including coolant, brake fluid, and differential/transmission fluid, should be checked and topped up if necessary, with a reminder that these fluids degrade over time regardless of mileage. If the vehicle has been stationary for significant periods, the exhaust system for corrosion and the suspension components for stiffness or binding should be examined, as standing vehicles are particularly vulnerable to these issues. Finally, verify that service records are up to date, particularly for oil changes and fluid servicing, as the last MOT does not guarantee compliance with manufacturer-recommended maintenance schedules.
