2012 London Taxis INT TX4 2.5L Diesel · LS12 EFX

The most recent MOT test conducted on 2 July 2026 resulted in a pass with no recorded defects. Evaluating the overall maintenance trend, the vehicle demonstrates a pattern of reactive maintenance rather than a strictly preventative approach. This is highlighted by the significant failure in August 2025, where multiple major defects were recorded concerning the front suspension ball joints and wishbone bushes. While the subsequent clean passes indicate that these critical steering and suspension components were addressed, the history suggests that the vehicle's front-end geometry and mounting components are high-wear areas that require consistent scrutiny. The recorded mileage of 390,290 miles is exceptionally high for a 14-year-old vehicle, averaging approximately 27,878 miles per year. This level of usage is consistent with intensive commercial operation, such as a taxi service. Mechanically, this high mileage implies significant cumulative wear on the engine, gearbox, and drivetrain components. While high-frequency usage can sometimes prevent the issues associated with vehicles that sit idle, such as brake binding or battery degradation, it necessitates a much more rigorous inspection of all mechanical consumables and a heightened awareness of potential component fatigue in the engine and transmission. During a test drive, pay close attention to the front end of the vehicle for any signs of mechanical play. Listen for knocking, clunking, or creaking sounds when traversing uneven surfaces or turning the steering wheel, as these are primary symptoms of worn ball joints or perished bushes. You should also monitor for any steering wander or a vague sensation through the steering rack, which could indicate remaining play in the suspension or steering linkage. Furthermore, given the 2023 advisories regarding oil and water leaks, you must inspect the engine bay and the ground beneath the vehicle for any fresh signs of fluid weeping, particularly around the sump and the cooling system, as high-mileage seals are prone to gradual failure. Finally, conduct a thorough physical inspection of the tyres and braking system. Check for uneven or scalloped tyre wear, which often results from the suspension issues previously noted, and inspect the brake discs for heavy scoring or excessive lip formation. Ensure there is no evidence of binding calipers, which may cause overheating or uneven braking performance. Given the vehicle's age and extensive mileage, it is imperative to verify the service history to ensure all major maintenance intervals have been strictly adhered to. You should also inspect the chassis and exhaust system for signs of structural corrosion or fatigue, which can be accelerated by the high-mileage urban driving typical of this vehicle type.
