2017 Renault Master 2.3L Diesel · WX66 FXF

The Renault Master’s most recent MOT tests, conducted just four months ago on 3 March 2026, reveal a concerning pattern of repeated failures despite no recorded defects. Both tests at 258,924 miles were marked as failed without explanation, which contradicts the standard DVSA practice of specifying issues—this suggests either an administrative error or a vehicle that passed unconditionally in prior years. The previous cycle, tested in March 2025 at 254,644 miles, also resulted in a double failure, though again without defect details. This inconsistency undermines confidence in the vehicle’s roadworthiness, particularly if the failures were procedural rather than mechanical. The absence of advisories or defects across all tests implies either a meticulous owner or a tester overlooking critical components, though the repeated failures warrant scrutiny of high-wear items like brakes, suspension, or emissions systems. The recorded mileage of 258,924 miles over nine years equates to an average of nearly 28,800 miles annually, a rate significantly higher than the UK average for a vehicle of this age. This suggests either intensive commercial use or prolonged periods of high-mileage operation. The gaps between tests—roughly 12 months—are standard, but the lack of intermediate maintenance records or advisories in the MOT history raises questions about whether critical services were performed between tests. The jump from 247,376 miles in February 2024 to 254,644 miles by March 2025 (7,268 miles in under a year) and then another 4,280 miles by March 2026 indicates variable usage, which could accelerate wear on drivetrain components, suspension bushes, and brake systems. Given the repeated failures and high mileage, a prospective buyer should prioritise an independent inspection of the brake system—particularly rear calipers and discs—for binding or uneven wear, as this is a common cause of MOT failures. The suspension should be examined for degraded bushes, worn coil springs, or corrosion in the subframe or trailing arms, especially given the vehicle’s age and mileage. Exhaust emissions should also be tested, as repeated failures could indicate a failing catalytic converter or oxygen sensor. Structural integrity, particularly around the wheel arches and sills, should be checked for corrosion, as this van model is prone to rust in high-mileage examples. The absence of advisories in the MOT history does not guarantee these areas are sound, so visual and functional checks are essential.
