2015 Renault Master 2.3L Diesel · AY15 AFK

The Renault Master’s most recent MOT test on 2024-03-18—just 26 months ago—shows a concerning pattern of instability rather than consistent roadworthiness. Despite two tests conducted on the same day at 236,733 miles, one passed while the other failed without recorded defects, this duplication suggests either an administrative error or an unresolved issue that evaded detection. The preceding tests in 2023 and 2022 also reveal a similar inconsistency: two tests at 192,488 miles in March 2022, one passing and one failing, with no defects logged. This lack of clarity implies either a history of rushed or incomplete inspections or a vehicle prone to intermittent failures. The absence of advisories or defects in the passing tests does not negate the risk—it merely indicates the tester did not identify critical issues at the time. The mileage progression of 236,733 miles over 11 years—an average of 21,521 miles annually—is unusually high for a vehicle of this age, particularly given the Renault Master’s typical usage patterns. Between 2022 and 2023, the vehicle accumulated 22,116 miles in just under a year, a rate that accelerates wear on high-stress components like suspension bushes, coil springs, and brake calipers. The gap between tests in 2022 (March) and 2023 (April) is also unusually short for a vehicle with this mileage, suggesting either a deliberate attempt to avoid failures or a lack of consistent maintenance. Such rapid mileage accumulation, combined with the repeated MOT test anomalies, raises questions about whether the vehicle has undergone proper servicing or if critical components have been overlooked. Given the inconsistent MOT history, a buyer should prioritise an independent inspection of the suspension system, particularly the rear axle and coil springs, as binding or worn components could explain the intermittent failures. The brakes, especially the rear calipers and discs, warrant close examination for uneven wear or corrosion, which might have been missed during the tests. Structural integrity should also be assessed, focusing on the chassis and subframe for signs of rust or distortion, particularly around wheel arches and the exhaust system. The repeated test anomalies imply a history of either poor maintenance or a vehicle prone to undetected faults, so verifying the condition of the exhaust emissions system and fuel injection components would further clarify whether the engine is running efficiently or contributing to intermittent failures.
