2009 Mitsubishi L200 2.5L Diesel · ST09 BGV

A pattern of suspension and brake-related wear dominates the mechanical record of this 2009 Mitsubishi L200, with a dangerous upper suspension arm ball joint failure on the nearside front at the June 2024 test standing out as the most serious recorded defect. That failure was rectified the following day when the vehicle returned with a pass, but the same test exposed a corroded and grease-coated nearside front brake pipe, low rear parking brake efficiency on the nearside, a binding service brake suspected of worsening under heat, a non-excessive oil leak, and a damaged but serviceable steering rack gaiter. The 2023 tests show an identical pattern of pre-existing concerns being flagged at both the failed and subsequent passed attempts, including fluctuating front service brake performance, a brake slack adjuster requiring attention, and oil leaks from both the engine and gearbox. The 2022 entry rounds out a consistent theme of front-end mechanical wear, with play detected in the offside front anti-roll bar ball joint alongside the recurring engine oil leak. Taken together, the record reflects a working vehicle with chronic front suspension, braking, and sealing issues that have been addressed each year but keep reappearing at test time. With 177,085 miles spread across roughly seventeen years of use, this L200 has averaged around 10,400 miles annually, which is a broadly typical accumulation rate for a working pickup of its age. There are no extended gaps in the MOT history that would indicate prolonged off-road storage, and the mileage progression between tests is steady rather than erratic, suggesting the vehicle has remained in regular service. For a diesel pickup of this vintage and mileage, that level of use means wear items such as suspension bushes, ball joints, brake calipers, discs, and drivetrain seals are well into their second or third lifecycle, and the recorded defects align closely with what would be expected from a truck that has worked consistently rather than one that has been laid up. A prospective buyer should focus the physical inspection on the front suspension geometry, paying particular attention to any clunks or knocks from the nearside front over uneven surfaces, as the dangerous ball joint detachment noted in 2024 indicates the upper arm assembly has already been disturbed and may be approaching the limits of its service life. The steering rack gaiter should be examined for splits beyond the recorded minor damage, and the area around the rack boots watched for fresh grease, which would point to worn inner tie rod joints. On the test drive, listen for wandering or instability under braking and feel for any pulling to one side, as the fluctuating service brake readings and binding caliper concern from the 2024 advisories suggest uneven caliper operation that may worsen when hot. A firm application of the parking brake on an incline is worth carrying out, given the persistent low nearside rear parking brake reading compared to the offside, which can indicate a seized rear caliper mechanism, stretched cable, or worn rear shoes. Underneath the vehicle, the nearside front brake pipe and its routing along the chassis should be inspected closely for corrosion bubbling under any grease coating, as this is a common failure point on L200s of this generation and was flagged at the most recent test. The engine and gearbox should be checked from below for active dripping rather than just residue, since the persistent oil leak advisories from both units could escalate if left unaddressed, particularly given the mileage. Finally, the offside front anti-roll bar link should be lifted and checked for play at the ball joint, as the 2022 advisory suggests this component may now be due for replacement, and any looseness there will transmit as a noticeable rattle over speed humps and a lack of body control during cornering.
