2016 Renault Master 2.3L Diesel · MX66 FWW

The Renault Master’s most recent MOT tests, conducted just four months ago on 2026-03-25, reveal an unusual but technically stable roadworthiness status. Despite two back-to-back tests at identical mileage—one passing and one failing without recorded defects—the lack of recurring failures suggests the vehicle was either retested for administrative reasons or the tester’s notes were incomplete. The absence of advisories or defects across all five tests implies no persistent mechanical issues, though the failed test at the same mileage warrants scrutiny of whether the vehicle was deliberately retested or if an oversight occurred. For now, the trend appears neutral rather than worsening or improving, but the retest anomaly should prompt a closer inspection of the braking system, suspension, and structural components, as these are the most commonly misreported areas in MOT failures. The vehicle’s recorded mileage of 40,510 miles over approximately ten years—roughly 4,050 miles annually—indicates unusually light usage for its age. The gap between the 2024 test at 30,184 miles and the 2025 test at 34,458 miles suggests a 4,274-mile accumulation in just over a year, followed by another 6,052 miles to reach the 2026 test. While this pattern avoids extreme wear, the prolonged periods between tests (over 12 months between 2024 and 2025) raise questions about whether the vehicle was stored or driven sporadically. Low mileage can mask underlying issues, particularly in components prone to degradation from inactivity, such as suspension bushes, coil springs, and fuel system seals. Given the lack of recorded defects, a buyer should prioritise an independent inspection of the suspension geometry, particularly the rear axle alignment and condition of the bushes and coil springs, as these are often overlooked in low-mileage vehicles. The braking system—despite no MOT failures—should be tested for uneven pad wear, binding calipers, or corrosion on the discs, especially if the vehicle was stored for extended periods. Structural integrity, particularly around the wheel arches, sills, and underbody, should be examined for corrosion, as rust can develop even in lightly used vehicles when exposed to moisture. Finally, the exhaust system and emissions components should be checked for leaks or blockages, as these are common failure points in diesel vehicles of this age, even with low mileage. The retest anomaly also justifies verifying the vehicle’s service history for any unrecorded maintenance or modifications.
