2004 Daihatsu Terios 1.3L Petrol · AX04 AWZ

The most recent MOT test on the 2004 Daihatsu Térios occurred on 2023-09-05, resulting in a failure with multiple major defects, including an Engine Management System (EMS) fault, poor exhaust emissions, and a malfunctioning fuel cap. This follows a pattern of fluctuating MOT outcomes, with prior tests in 2022 showing advisories related to brake wear and binding, alongside a minor but critical failure of the offside front CV joint boot in 2022-08-25. The vehicle’s MOT history is not uniformly stable; while some advisories were present in earlier tests, the 2023 failure highlights unresolved mechanical issues, particularly in the drivetrain, exhaust system, and electrical components, which suggest a lack of consistent maintenance or potential neglect of recurring problems. The presence of both major and minor failures indicates that the vehicle has not been adequately serviced to address wear and potential structural or component degradation over time. The recorded mileage of 66,809 miles for a vehicle aged approximately 22 years represents a remarkably low annual usage rate of around 3,037 miles per year, which is exceptionally low for its age. Such low mileage can often reflect periods of prolonged inactivity, particularly if the vehicle was stored or used infrequently, rather than a high-performance driving regimen. However, this usage pattern may mask underlying issues, as standing vehicles are prone to specific wear and corrosion problems, such as brake binding from static corrosion, suspension component degradation from lack of movement, and fluid degradation due to stagnation. The absence of higher mileage accumulation does not necessarily mean the vehicle is well-maintained, as it could simply mean it was not driven regularly, leaving critical systems vulnerable to silent deterioration. Given the vehicle’s MOT history and the recurring advisories and failures, the buyer should conduct a thorough pre-purchase inspection focusing on the drivetrain, braking system, and structural integrity. Inspect the front and rear CV joint boots for leaks or splits, as the 2022-08-25 MOT failure highlighted severe deterioration of both the near-side and offside boots, which could lead to drivetrain failure if ignored. Listen for unusual clunking or grinding noises from the suspension during a test drive, as the 2022-08-25 failure noted significant corrosion on the rear suspension mounting, which may cause structural weakness or excessive play. Check for uneven brake pad wear, brake pipe corrosion, and binding—symptoms of which were noted in prior MOTs—by testing the braking system at varying speeds and ensuring no shuddering or excessive vibration upon application. Additionally, verify the exhaust system for leaks or poor emissions performance, as the 2023 failure indicated persistent issues with lambda sensor readings, which could lead to engine misfires or increased emissions if not addressed. For the buyer, the vehicle’s age and low mileage suggest that certain time-based checks are particularly important. Inspect the tyres for signs of sidewall cracking or perishing, which can occur even at low mileage due to prolonged exposure to UV light and environmental conditions. Test the 12V battery for charge retention and overall health, as standing vehicles are prone to battery failure from discharge and corrosion. Check for signs of standing corrosion on the chassis, especially around wheel arches, door sills, and undercarriage, as the 2021 MOT noted some corrosion but did not indicate structural compromise. Finally, ensure that all fluids—oil, coolant, brake fluid, and transmission fluid—are at the correct levels and free from contamination, as stagnation can accelerate degradation. If possible, obtain a service history to confirm whether routine maintenance such as oil changes, brake inspections, and suspension servicing have been conducted, as the current MOT failures suggest gaps in this critical care.
