2006 Renault Master 2.5L Diesel · RO06 GXM

The most recent MOT test results, conducted on 2026-08-05, show the vehicle failed despite passing the same test just one month prior, indicating a persistent but not catastrophic set of issues. The recurring failures highlight a pattern of persistent minor defects in the front drive shaft boots, suspension ball joints, and steering components, alongside a persistent but non-excessive oil leak. While the 2024 MOT was clean, the subsequent failures suggest either a failure to address prior advisories or underlying wear progression that has not yet reached a critical threshold. The presence of multiple advisories—particularly the slight play in the offside front wheel bearing and the structural corrosion advisory—demonstrates that the vehicle’s mechanical integrity is under strain, though the structural advisories remain within acceptable limits for roadworthiness. This trend warrants cautious optimism but underscores the need for proactive maintenance to prevent escalation. The vehicle’s recorded mileage of 174,222 miles over approximately 20 years represents an average of around 8,711 miles annually, which is on the higher side for a 20-year-old Renault Master but aligns with typical usage patterns for vehicles in this category, particularly those with mixed operational profiles. However, the absence of significant mileage gaps between MOT tests—such as the 2023 test occurring just 13 months after the 2022 failure—suggests either consistent use or a lack of routine servicing. Higher mileage accelerates wear on consumables like brake pads, suspension components, and drivetrain seals, which aligns with the observed CV joint boot failures and oil leakage. The rapid accumulation of miles without corresponding service intervals could exacerbate existing wear, particularly in the suspension and drivetrain, where minor defects like the deteriorated ball joint dust covers and CV boots are now critical to monitor closely. Given the recurring CV joint boot failures and the persistent oil leak, the buyer should prioritise a thorough inspection of the front drivetrain and suspension system. On a test drive, listen for unusual noises from the front wheels, particularly clunks or grinding sounds that could indicate failing ball joints or worn wheel bearings. Check for oil leaks around the CV joints, transmission, and engine bay, and visually inspect the boots for any signs of excessive wear or tears. The slight play and noise in the offside front wheel bearing should prompt a closer inspection of wheel alignment and bearing condition, as bearing failure can lead to uneven tyre wear and steering play. Additionally, the structural corrosion advisory suggests that the vehicle has been exposed to moisture, which could accelerate rust in areas like the undercarriage or wheel arches. Inspect these regions for signs of corrosion, particularly around the suspension mounts and exhaust system, as rust can compromise structural integrity over time. For the buyer, the next critical steps involve addressing the immediate wear concerns while planning for longer-term maintenance. Replace the severely deteriorated CV joint boots promptly, as they are critical to preventing drivetrain contamination and potential transmission damage. The oil leak should be diagnosed and repaired to prevent further contamination of the drivetrain fluids, which can degrade engine and transmission components. Beyond the immediate defects, the buyer should schedule a comprehensive service that includes a full brake inspection, suspension component checks, and a fluid top-up, particularly the engine oil and coolant. Given the vehicle’s age and mileage, consider a thorough inspection of the exhaust system for signs of wear or leaks, as well as the brake system for signs of corrosion or binding calipers, which are common in vehicles that stand for extended periods. Finally, since the vehicle has been used extensively, check the tyre tread depth and sidewall condition for signs of perishing or uneven wear, as well as the 12V battery health, which can degrade with age and disuse. If the battery is old or weak, consider replacing it to avoid electrical issues, especially in the headlamps and other electrical systems.
