2016 Dacia Sandero 1.1L Petrol · AE16 RXB

This Dacia Sandero’s most recent MOT test on 2025-09-08—just ten months ago—shows no recorded defects, yet the vehicle failed the same day on the same mileage (65,995). While the 2024 and 2023 tests were clean, the duplicate failure in September 2025 suggests either an administrative error or an undetected issue that slipped through testing. The absence of advisories or repeated faults in prior years implies the vehicle has not suffered progressive wear, but the double failure at the latest test warrants scrutiny of components that might have narrowly missed failing—particularly brakes, suspension, or emissions systems. The fact that no defects were logged on the pass suggests the tester may have overlooked a marginal condition, which could recur. The mileage progression of roughly 6,600 miles annually aligns with typical usage for a vehicle of this age, with no abrupt jumps or prolonged stagnation. Between 2023 and 2024, the mileage increased by 6,596 miles, and another 5,565 miles were logged by September 2025. While this pattern avoids the extreme wear associated with high mileage, it also means components like brake pads, suspension bushes, and timing belts have likely reached or exceeded their service intervals. The lack of gaps in testing suggests consistent registration, but the double failure in 2025 could indicate a component nearing failure—such as worn brake calipers or failing catalytic converter—rather than neglect. A buyer should prioritise an independent inspection of the braking system, particularly the rear calipers and discs, given the 2025 failure context. The suspension should be checked for worn bushes or sagging coil springs, as these are common failure points in this model. Corrosion at wheel arches, subframes, and sills—often overlooked in annual tests—should also be examined, as rust can compromise structural integrity. Emissions systems, including the lambda probe and catalytic converter, may warrant closer inspection, especially if the vehicle exhibits rough idling or reduced power. Given the double failure in 2025, a pre-purchase diagnostic scan for hidden faults would be prudent.
