2015 Ford Mondeo 2.0L Diesel · EO03 ADE

The vehicle most recently passed its MOT on 29 September 2025, but the overall maintenance trend is concerning and appears to be deteriorating. While the 2023 inspection was clean, the subsequent two years have seen a recurrence of oil leaks and the emergence of structural corrosion advisories. The persistence of these issues suggests a reactive rather than proactive approach to maintenance, with several defects remaining unaddressed across multiple testing cycles. With a recorded mileage of 156,838 miles over an eleven year period, this vehicle has averaged approximately 14,258 miles per year. This is considered high usage, which places significant stress on all primary mechanical systems. A buyer should anticipate accelerated wear on the engine internals, gearbox, and drivetrain. Specifically, at this mileage, the condition of the timing belt, water pump, and clutch assembly is critical, as these components are likely approaching the end of their service life or are overdue for replacement. The recurring advisory for an oil leak, present since 2021, requires a thorough physical inspection. Check for seepage around the engine block and sump, and be alert for the smell of burning oil during a test drive. More critical is the reported corrosion on the rear sub-frame and under-vehicle chassis. You must inspect these areas for deep pitting or flaking metal, as structural corrosion can lead to expensive welding requirements or MOT failure if the integrity of the chassis is compromised. Attention must be paid to the rear tyres, which have shown a progression from perishing and cracking in 2024 to edge wear and legal limit concerns in 2025. Edge wear often indicates worn suspension bushes or incorrect wheel alignment, which can lead to premature tyre failure. During the test drive, listen for suspension clunks or knocks over uneven surfaces and ensure the vehicle tracks straight. Finally, verify the service history to confirm that oil and filter changes have been performed frequently enough to mitigate the effects of such high mileage.
