2004 Subaru Forester 2.0L Petrol · PL54 DYN

The most recent MOT test for this 2004 Subaru Forester was conducted on 2024-10-23 and resulted in a pass, though it included two advisories that warrant careful attention. The overall maintenance trend over the past decade is mixed, with a notable pattern of recurring issues—particularly in the suspension, exhaust system, and braking components—reflecting wear and potential underlying failures. The vehicle failed multiple times due to exhaust emissions faults, structural corrosion in the suspension mountings, and brake system deficiencies, indicating that while the car has been tested regularly, some critical areas have not been addressed comprehensively. The presence of persistent advisories on wheel bearings and anti-roll bar components suggests ongoing mechanical fatigue, which could escalate if not monitored closely, especially given the vehicle’s advanced age and accumulated mileage. The recorded mileage of 114,010 miles for a car aged approximately 22 years represents a relatively low annual usage rate of around 5,182 miles per year, which is unusually low for its age. Such low mileage often correlates with periods of prolonged standing or infrequent use, which can exacerbate issues like corrosion, fluid degradation, and component dryness. However, the absence of higher mileage accumulation does not necessarily mean the vehicle is well-maintained; instead, it may have been subjected to neglect or stored in conditions that accelerate wear. For example, standing corrosion—particularly in the suspension mountings and brake components—is more likely to develop when a vehicle is not driven regularly, as moisture and contaminants can penetrate sealed areas. Additionally, fluids such as brake fluid and differential oil can degrade over time due to evaporation or contamination, even without significant mileage. Given the vehicle’s age and the history of structural and mechanical advisories, the prospective buyer should conduct a thorough physical inspection. Focus on the suspension components, particularly the anti-roll bars and wheel bearings, for signs of excessive play, noise during cornering, or visible wear on the pins or bushes. Listen for unusual clunking or rattling when driving over bumps, as these could indicate failing suspension bushes or corroded mountings. The brakes should be inspected for uneven wear, binding calipers, or corrosion on the discs and pads, as the 2016 and 2018 MOT failures highlight past deficiencies. Check for fluid leaks around the brake system, especially near the rear brake pipes, which were noted as corroded in previous tests. The exhaust system should be examined for signs of deterioration, such as cracks or excessive rust, and listen for abnormal noises or reduced exhaust flow, which may indicate internal damage or emissions-related issues. For items not covered by the MOT, the buyer should verify the condition of the tyres, ensuring they meet minimum legal tread depths and checking for sidewall perishing or cracking, which can compromise structural integrity. Given the low annual mileage, the battery should be tested for strength, as prolonged disuse can lead to sulfation or reduced capacity. Inspect the underbody for signs of underseal failure or rust progression, particularly around the inner sills where previous MOT failures were noted. Fluid levels—including coolant, oil, and differential fluid—should be topped up, and the service history should be reviewed to confirm compliance with manufacturer-recommended maintenance intervals, such as the 12-month or 12,000-mile oil change schedule. Finally, a professional diagnostic check of the engine’s electrical system, including the hazard warning switch and engine control unit (ECU), is advisable, as past MOT failures suggest persistent issues in this area.
