2015 Peugeot 308 1.6L Diesel · SW15 SOA

The latest MOT test result for the 2015 Peugeot 308 at 72,135 miles indicates a failure on 2026-02-17, with three critical defects—front inner brake pads below the legal minimum thickness, nearside and offside front tyres with tread depths below the legal limit of 1.6 mm—and an advisory for worn, pitted front brake discs. This contrasts sharply with the clean MOT results from the preceding three years, suggesting a sudden deterioration in brake system integrity and tyre condition. The presence of both a dangerous failure for brake pads and an advisory for the discs indicates a likely progression of wear, possibly due to prolonged low-speed driving, uneven braking habits, or previous undetected issues that exacerbated pad and disc degradation. The prior MOTs without such failures imply that the owner may have either neglected routine brake inspections or the vehicle was driven in a manner that accelerated wear beyond typical expectations. The vehicle’s mileage of 72,135 miles over approximately 11 years represents a moderate annual usage rate of around 6,558 miles, which is consistent with its age and typical driving patterns for a model of this class. However, the absence of significant mileage gaps between MOT tests—particularly the sudden failures in 2026—could imply either a period of higher-than-average usage or a vehicle that was left stationary for extended periods, leading to accelerated corrosion and fluid degradation. For example, standing brakes can cause caliper binding, corrosion on brake discs, and uneven pad wear, while prolonged idling may contribute to oil and coolant breakdown. Additionally, the recorded tyres being worn close to the legal limit in 2021 and failing in 2026 suggests either aggressive cornering or road conditions that accelerated tread wear, or a lack of regular tyre rotation. Given the recent MOT failures, the prospective buyer must prioritise a thorough inspection of the brake system, focusing on the front discs and pads. Visually inspect the brake discs for excessive pitting, scoring, or warping, and check for uneven wear patterns that could indicate misalignment or binding calipers. On a test drive, listen for unusual grinding noises during braking, which may signal pad-to-disc contact or caliper binding. Brake pedal feel should be firm and consistent, with no sponginess or excessive travel, and the vehicle should not pull to one side when braking. Additionally, verify that the brake fluid level is adequate and check for leaks under the vehicle. The failed tyres require immediate replacement, as tread depths below 1.6 mm pose a safety risk and are illegal on public roads. The constant velocity (CV) boot failures from 2023 suggest that the drive shafts may be susceptible to further ingress of contaminants, so inspect the boot seals for signs of wear or cracking and consider a professional inspection of the shaft seals and universal joints. For the buyer, given the vehicle’s age and the recurring advisories and failures, a comprehensive pre-purchase inspection is strongly advised. Beyond the immediate issues, check the vehicle’s suspension for signs of worn suspension bushes, coil spring damage, or alignment problems, as these can exacerbate tyre wear and contribute to handling issues. Inspect the exhaust system for corrosion or leaks, which could indicate underlying structural or weld integrity problems. Pay particular attention to the engine bay for fluid leaks, particularly coolant and oil, as these can signal failing seals or gaskets. Given the vehicle’s mileage, also verify the service history for fluid changes, particularly brake fluid (which should be replaced every 2–3 years due to moisture absorption), transmission fluid, and coolant. Finally, test the 12V battery and starter system, as prolonged idling or standing can lead to battery discharge or electrical issues. If the vehicle has been driven regularly, the mileage suggests it has likely undergone routine servicing, but if it has been stationary for long periods, the owner may need to address potential corrosion risks to the undercarriage and structural components.
