2015 London Taxis INT TX4 2.5L Diesel · LL15 BYW

The most recent DVSA MOT test for this 2015 LONDON TAXIS INT TX4 was conducted on 10 November 2025 and resulted in a PASS, with no defects or advisories recorded against the vehicle. This follows an unbroken run of passes from November 2025, May 2025, November 2024, and June 2024, with the only previous failure being recorded on the same June 2024 date and likewise showing no defects, suggesting a likely administrative or retest situation rather than a mechanical issue. Overall, the test history indicates a stable maintenance trend with no advisories flagging component wear or deterioration, which is a positive indicator of consistent servicing given the heavy-duty nature of this taxi application. The absence of advisories over four consecutive tests demonstrates that brake, suspension, tyre, and exhaust components have remained within legal and serviceable thresholds at the point of test, although the extreme mileage still demands a thorough physical inspection. With 420,822 miles recorded over approximately eleven years, this TX4 is accruing roughly 38,257 miles annually, which is exceptionally high and characteristic of intensive commercial taxi operation. At this accumulated mileage, virtually every major mechanical system will have experienced significant wear, including the engine, transmission, clutch, suspension, braking components, and drivetrain. The MOT history shows no discernible mileage gaps, confirming continuous heavy use rather than periods of standing, which is mechanically preferable in some respects as prolonged standing can lead to seized calipers, perished tyres, and fluid degradation. However, such high annual mileage means that components such as timing belts, water pumps, clutch assemblies, and turbochargers will have likely been replaced multiple times, and a comprehensive service history verifying these renewals is essential. Given the clean MOT record and absence of advisories, the prospective buyer should still conduct a thorough physical inspection focused on age and mileage-related wear rather than relying solely on test outcomes. The tyres should be examined closely for tread depth, uneven wear patterns which may indicate suspension or alignment issues, and crucially for sidewall perishing or cracking given that rubber compounds deteriorate with age regardless of mileage, and taxi tyres often suffer accelerated shoulder wear from heavy cornering. The braking system warrants particular scrutiny, including a check for binding calipers, worn brake discs with lipping or corrosion, and the condition of flexible brake hoses which can degrade internally. Under the bonnet, the coolant, brake fluid, and power steering fluid should be inspected for age-related contamination, as fluids degrade over time irrespective of mileage and require periodic replacement to maintain system integrity. On the test drive, careful attention should be paid to any suspension clunks or knocking over uneven surfaces, which could indicate worn bushes, tired shock absorbers, or weakened coil springs given the heavy commercial loads this vehicle has carried. The clutch should be tested for slip under load, the gearbox assessed for smooth engagement across all ratios, and the steering checked for excessive play or wandering which may suggest worn track rod ends or steering rack wear. The 12V battery should be load tested as taxi vehicles frequently suffer from short journey profiles that prevent full charging, leading to premature battery failure. Finally, the underside should be examined on a ramp for exhaust integrity, fluid leaks from the engine and transmission, and corrosion on structural members, while verifying the service book stamps and any invoices for major component replacements such as the timing belt, clutch, and turbocharger to substantiate the documented mileage and confirm that this high-use vehicle has been maintained to a commercial standard throughout its working life.
