2020 Mitsubishi L200 Barbarian X DI-D Auto 2.3L Diesel · WM69 NRL

A pattern of intermittent brake and emissions-related failures sits at the heart of this L200's MOT record, with the vehicle passing cleanly in 2024 and 2025 before encountering two simultaneous defects on the same inspection date in April 2026. The dangerous front brake pad finding from March 2025, where the offside pad was recorded below 1.5 mm, indicates that pad wear on this pick-up should be monitored closely rather than assumed acceptable between services. The April 2026 test ultimately passed on the same day, but only after a prior failed entry for an inoperative engine management indicator lamp (MIL) and an underperforming windscreen washer, alongside a minor registration plate lamp defect. While the recorded issues have been remedied to achieve current roadworthiness, the recurrence of brake and dashboard warning lamp faults within a twelve-month window points to components that may not have been addressed at their root cause and warrant close scrutiny. Covering roughly 12,912 miles annually, this 2020 L200 has accumulated mileage well above the typical range for its age, which translates directly into elevated wear on consumable braking items, clutch friction material within the automatic transmission's torque converter interface, suspension bushes, and drivetrain mounts. There are no unusual gaps between test entries, indicating the vehicle has remained in continuous service rather than standing idle, which generally supports fluid condition but accelerates mechanical degradation. The combination of high annual mileage and commercial-style usage expectations for a Barbarian X pick-up means attention should focus on rear leaf spring bushes, prop-shaft universal joints, and the four-wheel-drive transfer box, all of which suffer under sustained load. For a prospective test drive, begin with a cold start and observe whether the engine management warning lamp extinguishes promptly and whether the diesel particulate filter completes any active regeneration cycles without excessive smoke or rough running, given the recent MIL inoperative fault. Carry out a measured stop from around 30 mph to assess for any pulling to the offside, pedal pulsation suggesting front disc warping following the recent pad replacement, or binding from a reluctant caliper sliding pin. Listen carefully for clonks or squeaks from the front suspension over speed bumps, paying particular attention to the offside front damper top mount and lower wishbone bushes, and check that the windscreen washers now deliver a strong, well-directed jet to both sides of the screen. A physical inspection should include close examination of the offside front brake caliper, pad wear remaining on the inner and outer pads, and the disc surface condition for hot spots or lipping, as the dangerous thickness reading suggests this corner may have been operating close to its wear limit. Verify that all dashboard warning lamps illuminate and extinguish correctly during the ignition bulb check cycle, and confirm the registration plate lamps function across all positions. With elevated mileage already logged and brake component wear actively recorded, plan for replacement of front discs alongside the recent pad set, a transmission fluid and filter service if not evidenced by documentation, and a thorough inspection of the underbody for any corrosion forming on the subframe, brake pipes, and fuel lines, particularly given the commercial duty cycle a Barbarian X typically endures.
