2015 Ford Focus 1.5L Diesel · ST15 OSO

The most recent MOT test on the 2015 Ford Focus, conducted on 2026-02-24, resulted in a clean pass with only minor advisories that do not affect roadworthiness. The overall maintenance trend appears stable, with no failures and only persistent, non-critical issues—particularly oil leaks and front tyre wear—suggesting consistent but not aggressive wear patterns. The advisories on registration plate deterioration are irrelevant to mechanical integrity and are purely cosmetic, while the oil leak advisories remain at a low severity level, indicating no significant fluid loss or damage to surrounding components. The presence of misted front shock absorbers on the offside is also concerning but not severe, as misting alone does not necessarily imply imminent failure unless accompanied by excessive body roll or harsh ride quality during cornering. The vehicle’s recorded mileage of 147,485 miles for a 11-year-old car represents a high annual usage rate of approximately 13,408 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and fluid systems, as well as on structural elements exposed to repeated stress. The absence of significant service intervals or long periods of stationary use may also contribute to issues such as standing corrosion on brake discs or calipers, which can lead to binding or reduced braking efficiency. Additionally, the rapid mileage suggests potential overuse of the vehicle, which could exacerbate wear on the drivetrain, exhaust system, and internal engine components over time. For a prospective buyer, the most critical areas to inspect during a physical examination include the front suspension and shock absorbers, as the DVSA advisories suggest ongoing wear. Look for signs of excessive body roll or uneven ride quality when cornering, which may indicate failing shock absorbers. Listen for clunking noises from the front suspension during acceleration or deceleration, as this could signal worn or broken suspension bushes or broken coil springs. The oil leak advisories warrant attention to the engine bay for any visible fluid pooling or discoloured stains, particularly near the oil pan or valve cover. Inspect the front tyres closely for uneven wear patterns, which may indicate misalignment or suspension issues, and confirm that the tread depth is legal and not excessively worn on the edges. Beyond the mechanical checks, the vehicle’s age and high mileage necessitate thorough attention to fluid condition and standing corrosion. Check the engine oil level and condition, ensuring it is free of contaminants and at the correct viscosity, as oil degradation accelerates with high mileage. Inspect the brake system for signs of corrosion or binding calipers, particularly if the vehicle has been stationary for extended periods, as this can compromise braking performance. Verify the battery health, as older vehicles with high mileage are more susceptible to weak or failing batteries, which can lead to electrical gremlins or poor starting. Finally, confirm that the service book is up to date, especially for fluid replacements like brake fluid, coolant, and transmission fluid, which degrade over time regardless of mileage. If no service records are available, prioritise a full fluid flush and a thorough inspection of the drivetrain and exhaust system for signs of wear or damage.
