2015 Mitsubishi ASX 1.8L Diesel · DF15 OCZ

The most recent MOT inspection on 6 March 2026 resulted in a pass, but the vehicle's maintenance profile shows a concerning trend of worsening mechanical advisories. While the vehicle passed after addressing a dangerous failure regarding nearside front tyre tread depth, the subsequent advisory list is more extensive than in previous years. The progression from simple wiper blade and tyre wear in 2025 to structural and braking concerns in 2026 suggests that the vehicle is entering a phase of increased component degradation. The presence of multiple advisories regarding corrosion and braking surfaces indicates that while the vehicle remains roadworthy, it is approaching a period where significant remedial expenditure will be required to maintain safety standards. With a recorded mileage of 97,050 miles over approximately eleven years, the vehicle has covered an average of roughly 8,823 miles per year. This represents typical, moderate usage for a petrol or diesel crossover of this age, suggesting it has not been subjected to extreme high-mileage motorway commuting nor has it suffered from the excessive stagnation often seen in very low-mileage vehicles. This steady usage pattern generally implies a consistent level of wear on drivetrain components and suspension, though the recent MOT results suggest that the cumulative effect of this mileage is now manifesting in the degradation of consumables and chassis components. A prospective buyer must pay close attention to the recurring advisories regarding the braking system and suspension. The advisory for pitted and scored rear brake discs, combined with previous notes of thinning pads, suggests the braking system is nearing the end of its service life. During a test drive, listen for any grinding noises during deceleration or a pulsating sensation through the brake pedal, which could indicate warped discs or binding calipers. Furthermore, the advisory regarding a corroded rear coil spring is a significant mechanical concern. Corroded springs are prone to sudden fracture, which can cause sudden changes in vehicle handling or audible clunking and knocking sounds when driving over undulations or speed bumps. You should visually inspect the rear suspension area for heavy surface rust or any signs of structural thinning. Finally, the history of tyre advisories, including cracking, perishing, and nail damage, indicates that the rubber components may be reaching the end of their reliable lifespan due to both wear and age-related degradation. Even if the tread depth appears sufficient, check the tyre sidewalls for any fine cracks or perishing, which can lead to sudden failure. Given the advisory regarding exhaust system corrosion from 2024, it is also prudent to inspect the underside of the vehicle for significant rust on the exhaust manifold and mounting brackets. Ensuring that the undertray is securely fitted, as noted in the latest test, is important for protecting these components, but the underlying corrosion should be monitored closely to prevent future structural failures.
