2011 London Taxis INT TX4 2.5L Diesel · LR11 DMU

A London Taxis TX4 of this vintage carrying 257,730 miles under its wheels and presenting five consecutive DVSA passes stretching back to September 2021 demonstrates a notably clean and consistent roadworthiness record. The most recent test on 16 October 2023 closed out without a single advisory or defect entry, and the earlier examinations through 2022 and into 2023 followed suit, returning clean sheets every time. With no recorded failures, no advisories flagged for corrosion, component wear, or exhaust integrity, and no structural concerns raised across five successive annual tests, the official record paints a picture of a vehicle that has consistently met the minimum statutory requirements without tester intervention. For a commercial-orientated taxi platform that is notorious for hard service cycles, the absence of even minor advisory notes is unusual and suggests the mechanical condition presented at test has been within typical serviceable limits. The annual mileage accumulation of roughly 17,182 miles sits at the upper end of expectations for a vehicle of this age and reflects its likely operational history as a working taxi. There are no extended gaps in the MOT testing sequence visible in the supplied history, which indicates the vehicle has remained in regular use and on the road throughout the recorded period, avoiding the long stationary lay-ups that often mask underlying deterioration in high-mileage commercial vehicles. Continuous service of this nature places sustained load on the drivetrain, braking system, and suspension components, meaning consumable wear will progress more rapidly than on a privately-owned equivalent. The mileage progression itself does not show any abrupt jumps or inconsistencies in the records provided, giving confidence that the odometer reading is a faithful representation of accumulated use rather than a clerical or tampering concern. Given the working-taxi provenance and high accumulated mileage, attention during a physical inspection should focus on the areas most stressed by urban commercial operation. The TX4 chassis is well known for rear axle bush wear, front lower wishbone deterioration, and anti-roll bar link failure, all of which manifest as clonking or knocking noises transmitted through the bulkhead over speed humps and uneven surfaces. Steering wander, imprecise turn-in, or a sensation of slack in the front end would point toward worn track rod ends or top mounts requiring replacement. On the road, any pulling to one side under braking, a soft or spongy pedal, or vibration through the steering wheel at speed would suggest front disc warping or caliper slide pin seizure, both common on vehicles that have completed this level of mileage. The 2.5-litre diesel drivetrain should be evaluated for signs of turbocharger wear, injector leak-back, and coolant system pressure loss, particularly around the plastic expansion tank and radiator matrix which are known weak points on the Iveco-derived unit. Diesel particulate filter condition is critical on a vehicle that has spent its life in stop-start urban traffic, so any evidence of frequent regeneration cycles, illuminated warnings, or restricted performance under load would warrant a diagnostic interrogation. A thorough underside examination is advisable to confirm the absence of corrosion on the rear subframe mounting points, handbrake mechanism, and fuel lines, areas that the clean MOT history does not necessarily cover if previous tests were conducted at facilities with limited lifting equipment. A compression test on a warm engine and an oil analysis for coolant contamination would offer further reassurance given the mileage accrued.
