2015 London Taxis INT TX4 2.5L Diesel · LR65 EBJ

A clean four-year MOT pass streak defines the mechanical story of this 2015 London Taxis International TX4, with the most recent test on 3 December 2025 returning a pass and zero recorded defects, mirroring the same outcome from December 2024, November 2023, and December 2022. The only blemish on the record is a fail dated 30 November 2022, but remarkably it carries no recorded defect entries, which strongly suggests an administrative or presentation issue at the time of test rather than a substantive mechanical or structural failure, as DVSA examiners are required to log specific reasons for refusal. The subsequent immediate re-test pass just five days later on 5 December 2022 reinforces this interpretation, and the consistent absence of advisories or defects across four consecutive tests points to a vehicle that has been kept in serviceable condition throughout the recent test cycle. For a taxi-derived vehicle operating in demanding urban conditions, this unbroken pattern of clean passes is a positive roadworthiness indicator, though the lack of advisory detail also means there is no recorded insight into borderline wear items that may now be approaching service thresholds. With 208,643 miles recorded against an eleven-year platform age, this TX4 has accumulated roughly 18,968 miles annually, a figure consistent with heavy commercial taxi utilisation rather than private ownership. There are no extended gaps in the testing history that would suggest long periods off the road, which is mechanically significant because TX4s left stationary for prolonged stretches often suffer from dry compression in the diesel injection system, seized callipers from infrequent brake application, and moisture accumulation in the clutch hydraulics. Conversely, the continuous high-mileage duty cycle means the engine, gearbox, clutch, and final drive have been kept thermally active and lubricated, which is generally favourable for long-term drivetrain longevity. The wear burden, however, falls disproportionately on suspension components, steering linkages, brake friction material, and the notoriously under-stressed TX4 rear semi-elliptic leaf springs, all of which will have absorbed hundreds of thousands of urban cycle impacts. Buyers should interpret this mileage as typical for the model rather than excessive, but should weight their inspection accordingly toward consumables that degrade with use rather than age. From a buyer inspection standpoint, the absence of any recorded advisory items across four tests is both reassuring and slightly limiting, because it removes the usual roadmap of borderline components to verify. A physical pre-purchase inspection should therefore concentrate on the TX4 known-weak areas: the front suspension wishbone bushes and anti-roll bar drop links, which on high-mileage examples commonly exhibit splitting and knocking that only manifest over uneven road surfaces; the rear leaf spring eyes and mounting shackles, where corrosion and elongation of the bushes produce audible clonking when traversing speed humps; and the steering rack gaiters and track rod ends, which on these vehicles frequently perish and allow grease loss followed by play. On a test drive, listen for any knocking, creaking, or shimmy from the front end over broken tarmac, pay particular attention to whether the steering self-centres promptly after cornering, and check for any pulling to one side that might indicate a worn lower arm bush rather than simply a wheel alignment issue. Given that the TX4 uses a hydraulic clutch system shared with older Land Rover platforms, the clutch pedal should be tested for a firm, consistent bite point without sponginess, and the brake pedal assessed for any excessive travel that could betray a binding or partially seized rear caliper. Brake condition deserves close scrutiny given the mileage, even though no defects were recorded, because DVSA testers only fail items at the legal minimum threshold rather than flagging mid-life wear. Inspect the visible portion of the front brake discs for a pronounced lip at the outer edge, which on a high-mileage taxi will likely exceed one millimetre and suggests the discs are nearing their second or third skim limit. Check that all four wheels rotate freely without drag when jacked, particularly the rear drums which on these vehicles are prone to stuck wheel cylinders and seized adjuster mechanisms that gradually pull the vehicle off-line. The exhaust system, especially the flexible joint downstream of the manifold and the rear silencer, should be examined for blueing, corrosion, or audible blowing under load, as TX4 diesel emissions compliance can be compromised by EGR valve carbon build-up rather than purely tailpipe condition. Finally, verify that the vehicle has been regularly serviced at sensible intervals given the mileage, with particular reference to cambelt replacement history on the 2.5-litre DJ/BJ diesel engine, timing chain condition on the earlier variants, and evidence of recent clutch or dual-mass flywheel work, all of which represent the most economically significant maintenance items on this platform at this odometer reading.
