2004 Toyota Yaris 1.3L Petrol · AF04 WVM

The most recent MOT test on the 2004 Toyota Yaris occurred on 2025-05-23, resulting in a failure due to critical issues with both near-side and offside windscreen wipers failing to clear the glass effectively, along with severe reduction in light output from the near-side headlamp lens. This failure pattern, coupled with earlier repeated failures in headlamp alignment and rear wheel bearing roughness, suggests a concerning trend of recurring mechanical and functional deficiencies rather than a stable maintenance trajectory. The vehicle’s history also reveals persistent advisories—such as oil leaks, exhaust system corrosion, and worn seat belt webbing—that, if left unaddressed, could escalate into major failures or compromise road safety. The presence of multiple near-side rear tyre advisories, including wear close to legal limits and signs of damage, further indicates that wear progression is not isolated to specific components but is a systemic concern. The recorded mileage of 48,752 miles for a vehicle aged approximately 22 years represents an unusually low annual usage rate of around 2,216 miles per year, which is far below the average for its age. Such low mileage can stem from infrequent use, long periods of stationary storage, or deliberate underutilisation, but it also raises important questions about the vehicle’s actual condition. Low-mileage vehicles can develop issues related to prolonged exposure to environmental elements, such as corrosion from standing, particularly in the exhaust system and undercarriage, which the MOT history has already flagged. Additionally, components like headlamps, wipers, and seat belts may degrade more rapidly due to lack of regular use, leading to the repeated failures observed. The absence of higher mileage accumulation suggests that wear on consumables like brakes, suspension components, and drivetrain elements may be less severe than one might expect, but this does not absolve the need for thorough inspection of these areas, especially given the history of wheel bearing and suspension-related advisories. For a prospective buyer considering this vehicle, the most critical areas to inspect during a test drive and physical examination include the rear wheel bearings, which have consistently failed or shown signs of roughness or noise in multiple MOT tests. Listen for a grinding or humming noise when the vehicle is stationary or moving slowly, particularly when turning, as this indicates bearing wear or failure. The near-side rear tyres, which have been worn close to legal limits and show signs of damage or perishing, should be closely examined for uneven wear patterns, which could suggest misalignment or suspension issues. Check for any fluid leaks around the engine bay and undercarriage, particularly near the oil pan and exhaust system, as the MOT history reports persistent oil leaks and exhaust corrosion. Inspect the exhaust for rust or corrosion, especially around the catalytic converter and mufflers, and listen for unusual noises or backpressure, which could indicate internal damage or blockages. Beyond the mechanical checks, the vehicle’s age and low mileage make it essential to address potential issues related to prolonged exposure and calendar-based degradation. Given the lack of recent service history, verify the condition of the brake system, including checking for corrosion on brake discs or signs of binding calipers, which can occur when the vehicle stands for extended periods. Inspect the tyre sidewalls for signs of cracking or perishing, which can weaken the tyre structure and compromise safety, even if the tread remains legal. Test the 12V battery for adequate charge and overall health, as low usage can lead to sulphation or weak terminals. Finally, ensure that all fluids—particularly engine oil, coolant, and brake fluid—are at the correct levels and not showing signs of degradation or contamination. Given the history of oil leaks, top up or replace fluids as necessary, and consider a comprehensive service to address any underlying issues before purchase.
