2023 MAN TGE 3.140 Lion XS Auto 2.0L Diesel · OY23 CSU

The 2023 MAN TGE 3.140 LION XS AUTO has recently undergone its most recent MOT test on 2026-09-01, which passed without any recorded defects, following a previous failure in January 2026. This marks a significant improvement in roadworthiness, as the vehicle previously failed due to a persistent engine malfunction indicator lamp (MIL) and defects in the diesel particulate filter (DPF) system, including a major leak of exhaust gases and critically low rear brake pad thickness. The absence of these issues in the latest test suggests either effective remedial work or a resolution of underlying mechanical problems, though the buyer should remain vigilant regarding the DPF’s long-term reliability and the potential for future emissions-related failures if the engine’s diagnostic system remains active. The recorded mileage of 49,703 miles for a vehicle of this age—approximately 16,568 miles per year—indicates a high annual usage rate, which can accelerate wear on critical components such as brakes, suspension, and drivetrain elements. At 3 years old, such mileage is unusually high for a vehicle that has not been subjected to heavy or prolonged operational stress, particularly if it has been stored for extended periods. This rapid mileage accumulation may suggest either intensive use, such as commercial or high-mileage personal driving, or potential issues with odometer accuracy. Regardless, the wear on consumables like brake pads, suspension bushes, and fluid systems will be more pronounced than in a lower-mileage equivalent, necessitating closer attention to signs of excessive friction, uneven tyre wear patterns, or unusual noises during a test drive. Given the vehicle’s recent MOT clearance and the presence of past DPF-related failures, the buyer should prioritise a thorough inspection of the exhaust system and emissions components. The DPF’s integrity is critical, as its failure can lead to severe engine performance degradation, increased fuel consumption, and potential black smoke emissions. Inspect the DPF for signs of blockage, cracking, or excessive soot buildup, and listen for any unusual exhaust noises or reduced power during acceleration, which may indicate clogging or backpressure issues. Additionally, verify the exhaust manifold and hoses for leaks or corrosion, as the January 2026 failure highlighted a major leak after the DPF, which could recur if the system remains defective. During the test drive, monitor for any engine warning lights or hesitation, particularly when under load, as these may signal persistent DPF or engine management system problems. For the brakes, the buyer should focus on the rear brake system, given the previous MOT failure regarding pad thickness. Although the latest MOT passed, the buyer should visually inspect the rear brake discs and pads for signs of glazing, warping, or excessive wear, and check for any binding or excessive play in the calipers. Listen for grinding noises when applying the brakes, as this could indicate metal-to-metal contact between the pads and discs, which may require immediate attention to prevent further damage or reduced braking effectiveness. The rear tyres should also be examined for uneven wear or signs of hydroplaning, as this could suggest misalignment or suspension issues that may have contributed to the previous brake-related failure. Lastly, given the vehicle’s age and high mileage, the buyer should consider a comprehensive fluid check, including the brake fluid reservoir, as standing brake fluid can absorb moisture and lead to corrosion or reduced braking performance over time.
