2019 Dacia Logan 1.5L Diesel · LL69 XJB

The latest MOT test outcome for the 2019 Dacia Logan reveals a critical failure on 2025-12-05, with major defects including an offside rear stop lamp non-functionality and a rough front wheel bearing on the offside wheel, alongside advisories for excessively worn front brake pads on both sides. This marks a significant deviation from the vehicle’s previous MOT history, which had consistently passed without defects until the previous year’s test. The failure pattern suggests a deterioration in both mechanical integrity and electrical systems, particularly in the rear lighting and wheel bearing assembly, which may indicate underlying issues such as corrosion, misalignment, or component fatigue. The absence of such failures in prior tests implies either a sudden onset of wear or a lack of prior maintenance addressing these critical components, warranting immediate attention to prevent further degradation. The recorded mileage of 219,775 miles for a vehicle aged seven years represents a high annual usage rate of approximately 31,396 miles per annum, which is notably elevated for its class and age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluid degradation over time. The absence of substantial mileage gaps between tests suggests either frequent use or a lack of long-term storage, both of which can exacerbate mechanical stress. The rapid wear observed in the front brake pads and wheel bearing further supports the likelihood of high-stress operation, potentially due to aggressive driving habits, heavy loads, or pre-existing substandard maintenance. Buyers should be aware that this level of usage may necessitate more frequent servicing and closer monitoring of critical systems to mitigate long-term reliability risks. Given the critical failures and recurring advisories identified in the MOT history, prospective buyers must conduct a thorough pre-purchase inspection to address the immediate safety concerns and prevent further damage. The offside rear stop lamp failure necessitates immediate replacement of the bulb or wiring harness to ensure compliance with roadworthiness standards and prevent accidents. The rough front wheel bearing on the offside wheel is a serious defect that could lead to wheel separation or catastrophic failure if left unaddressed; this requires immediate inspection of the bearing unit, wheel hub, and associated seals for signs of leakage or excessive play. During a test drive, listen for unusual grinding or clunking noises from the offside wheel, particularly when cornering or under acceleration, and check for excessive wheel run-out or vibration. Additionally, inspect the front brake pads for further thinning or glazing, which may indicate hydraulic issues or excessive heat buildup; test for brake pedal sponginess or a reduced stopping distance. Beyond the immediate defects, buyers should also verify the structural integrity of the nearside anti-roll bar linkage, which was deemed missing in a previous test, suggesting either a broken or detached component. This could lead to uneven suspension travel and increased wear on springs and dampers; visually inspect the linkage for continuity and check for any signs of bending or detachment. The engine MIL (Malfunction Indicator Light) failure from 2024 indicates an ongoing electrical or sensor issue that should be diagnosed by a qualified mechanic to prevent potential engine damage or reduced fuel efficiency. For the suspension, inspect the front coil springs and shock absorbers for signs of sagging, leaks, or excessive bounce, as well as the front suspension bushes for stiffness or excessive play, which could contribute to the wheel bearing roughness. Finally, ensure all fluids—brake, coolant, and transmission—are topped up and free from contamination, as high mileage and frequent use can accelerate fluid degradation. If the vehicle has been stored for extended periods, check for tyre sidewall cracking or perishing, which can compromise structural integrity, and verify that the 12V battery is fully charged and free from corrosion to avoid electrical system failures.
