2018 Renault Master 2.3L Diesel · HY18 AEN

Corrosion and progressive wear on the braking and suspension systems define the mechanical profile of this Renault Master, following a failed test in March 2025. While the vehicle passed its most recent inspection on 20 March 2026, the record shows a trend of accumulating advisories related to structural and component degradation. Specifically, the latest test flagged corrosion on the central rear anti-roll bar and both front coil springs, alongside wear in the nearside rear upper leaf spring shackle pin or bush. The recurring advisories regarding pitted or scored brake discs on both the front and rear axles suggest a consistent pattern of component wear that has persisted through multiple testing cycles. The recorded mileage of 144,238 miles for an eight-year-old vehicle indicates a high-intensity usage pattern, averaging approximately 18,030 miles per year. This level of annual accumulation is consistent with commercial or long-distance transit use, which places significant mechanical stress on the drivetrain, suspension, and braking systems. Such high mileage increases the likelihood of the accelerated wear observed in the MOT history, particularly regarding the degradation of consumables like brake discs, pads, and shock absorbers, as well as the onset of corrosion on chassis and suspension components. Prospective buyers should pay close attention to the braking system and suspension integrity during a physical inspection and test drive. The history of a major failure for a binding offside rear service brake and insufficient parking brake efficiency in 2025, combined with ongoing advisories for pitted discs, necessitates a thorough check of the calipers and parking brake mechanism. On a test drive, listen for any grinding noises during braking or a pulling sensation to one side, and feel for any pedal judder or sponginess which could indicate issues with the discs or hydraulic components. Suspension and chassis components also require scrutiny due to the documented corrosion and bushing wear. The advisories regarding the central rear anti-roll bar, front coil springs, and the nearside rear leaf spring bush suggest that the vehicle's ability to manage load and road irregularities may be compromised. During operation, listen for knocking or clunking sounds when driving over uneven surfaces or speed bumps, which could signal excessive play in the suspension bushes or weakened springs. Additionally, the light oil misting noted on the nearside rear shock absorber in 2025 should be visually inspected to ensure it has not progressed to an active leak.
