2021 Ford Transit Custom 300LEADER Eblue 2.0L Diesel · WN71 TVZ

High-intensity commercial usage defines the operational history of this Ford Transit Custom, which has accumulated 211,244 miles over its five-year lifespan. While the vehicle successfully passed its most recent MOT on 24 July 2026, the record reveals a transition from a clean testing history in 2024 and 2025 to a cluster of emerging mechanical concerns in the latest inspection. The presence of a deteriorated constant velocity boot, persistent tyre wear, and an engine oil leak indicates that the drivetrain and chassis components are now beginning to show the cumulative effects of heavy duty service. The annual average of approximately 42,249 miles suggests this vehicle has been subjected to continuous, long-distance operation rather than short-trip cycles. Mechanically, this high mileage profile places significant stress on the suspension geometry, wheel bearings, and drivetrain seals. Prospective buyers should note that the rapid accumulation of miles typically accelerates the fatigue of rubber bushings and steering linkages, which may not have been captured as formal failures yet but are likely nearing the end of their functional service life given the vehicle's total mileage. During a test drive, the reported oil leak requires careful investigation to determine its origin, as oil misting can often mask more significant seal failures or turbocharger issues common in high-mileage diesel engines. Inspect the underside for fresh fluid accumulation and listen for any abnormal whining from the turbocharger under load. The advisory regarding the front tyres being worn on the edge points to a potential misalignment of the front end, which can lead to premature wear of steering rack ends and track rod ends. Pay close attention to any steering pull or vibration through the steering wheel at motorway speeds, as these are primary indicators of underlying suspension geometry issues. The note regarding the severely deteriorated nearside front constant velocity boot is a critical point for immediate attention, as a split boot allows grease to escape and road grit to enter the joint, leading to rapid mechanical failure. Listen for rhythmic clicking or clunking sounds when executing tight, low-speed turns, as this is a hallmark symptom of a compromised CV joint. Furthermore, ensure that the stop lamps and headlamp systems remain fully functional, as the history of lighting-related failures suggests that the vehicle's electrical system may be prone to intermittent connectivity issues or bulb failure, necessitating a thorough check of all exterior lighting circuits before purchase.
