2016 London Taxis INT TX4 2.8L Diesel · LO66 OHT

A persistent pedal anti-slip failure is the defining mechanical thread running through this TX4's recent history, appearing as a present-and-to-rectify defect on both 2025-12-01 and 2026-05-28 before the vehicle ultimately passed the same day with no defects recorded. The pedal rubber or anti-slip surfacing on these TX4 cabs is a known wear item, and the fact that it has failed twice within roughly six months suggests the surface may be deteriorating quickly under heavy commercial use or that the replacement component being fitted is of marginal quality. While the vehicle has cleared every other annual test since 2023 without advisories, the repeated PRS on this single item means a buyer should not simply accept the current MOT certificate at face value; the pedal surface should be physically inspected on the day of viewing and the driver should be asked whether a replacement has been ordered or scheduled, as PRS defects can quickly return once they begin to lift or compress. With 233,855 miles accumulated over ten years of service, this TX4 is averaging just over 23,000 miles annually, which is firmly in the high-wear commercial bracket and consistent with taxi or private-hire utilisation. Mileage progression between tests is steady rather than erratic, with no evidence of a long standing period, clock inconsistency, or missing data that would warrant suspicion. The high annual accumulation has clear mechanical consequences: consumables such as brake pads, discs, tyres, drive belts and suspension bushes will have been turned over many times, and the diesel drivetrain will be approaching or well past the point at which major items such as clutch, dual-mass flywheel, turbocharger and injector refurbishment become realistic considerations. The clean advisory list against this mileage is a mixed signal, because it could equally reflect diligent preventative maintenance or simply that advisories are being addressed before test rather than recorded. For a physical inspection, particular attention should be directed to the brake pedal box and surrounding trim, checking that the anti-slip rubber is fully bonded, free of cuts, and not lifting at the edges, as this is the single component that has demonstrably failed twice. A test drive should include firm pedal applications to confirm a solid, consistent feel with no sponginess or excessive travel, and the brake pedal should be inspected for vertical play that might indicate worn pedal box bushes. Given the mileage, the underside should be examined on a ramp for any oil seepage from the engine sump, timing cover or injector pump area, as well as condition of the front suspension arms, anti-roll bar drop links and rear leaf spring bushes, all of which are prone to wear on heavily worked TX4s. Finally, a thorough road test listening for clonks or knocking from the front end over uneven surfaces, any pulling under braking that could indicate warped discs or a binding caliper, and smoke colour from the exhaust on start-up and under load will help confirm whether this high-mileage cab still has useful service life left.
