2007 Toyota Yaris 1.3L Petrol · NG07 LLE

The most recent MOT test on 10 November 2025 resulted in a pass, but it followed a failure earlier the same day for a Major defect concerning the front engine management indicator lamp, recorded as inoperative or indicating a malfunction under Section 8.2.1.2 (h) of the inspection manual. This is a notable entry, as it indicates the Malfunction Indicator Lamp was either not illuminating during the bulb check sequence or was active while the engine was running, suggesting an underlying engine management, emissions, or sensor fault that may or may not have been rectified. Reviewing the broader test history, the vehicle has demonstrated a generally stable maintenance profile with no repeat failures, though the accumulation of advisories relating to corrosion of the underside and sub-frame, along with suspension component wear, points to an ageing platform rather than any worsening mechanical decline. The progression from clean passes in 2019, 2020 and 2021 to advisory-laden passes in 2022, 2023 and 2024 is consistent with a vehicle entering the later stages of its service life, where cosmetic and structural deterioration become more prevalent but have not yet compromised roadworthiness. The recorded mileage of 60,700 miles on a 19 year old vehicle equates to an average annual mileage of roughly 3,195 miles, which is substantially below the typical UK usage figure and firmly in low-mileage territory. This figure suggests either genuinely light use or, more likely given the age, significant periods of standing or very irregular use. Such low annual mileage has distinct mechanical implications. Brakes, particularly the discs and pads, are susceptible to corrosion from lack of regular use, and calipers can seize or bind in their sliding mechanism. The engine, coolant, brake fluid and gearbox oil will all degrade over time regardless of mileage, so calendar-based servicing intervals become more critical than odometer-based ones. Standing periods also encourage deterioration of rubber components, including tyres, drive belts, hoses and suspension bushes, as well as discharge of the 12V battery. For a prospective buyer, the advisory history warrants close physical scrutiny. The 2023 advisory regarding the nearside rear tyre cracking or perishing is particularly relevant given the vehicle's age and low mileage, as tyres older than seven to eight years develop sidewall perishing even with adequate tread depth. Check the DOT date code on each tyre sidewall and replace any aged units regardless of tread. The 2023 advisories on both front suspension arm pins or bushes indicate early-stage wear that has not yet resulted in excessive movement, but on a test drive listen for clonking over speed humps or uneven road surfaces and check for uneven inner or outer tyre wear which would confirm bush deterioration. The 2024 advisories on sub-frame and underside corrosion, while not categorised as serious weakening, should prompt a thorough underbody inspection on a ramp or over a pit to assess the extent of corrosion, particularly around suspension mounting points, brake lines, fuel lines and the exhaust system, as these areas will continue to deteriorate on a vehicle of this vintage. Given the low mileage and age profile, several additional checks are strongly advisable. Confirm the age of the 12V battery, as a battery older than five years is likely to be at or near end of service life, and verify that the cooling system has been refreshed at appropriate calendar intervals, as old coolant loses its corrosion inhibition and freezes within the system. Inspect brake discs for surface corrosion and check that the calipers slide freely, as standing vehicles frequently develop binding calipers that produce pulling under braking or uneven pad wear. Request evidence of recent service work, particularly oil and filter changes, brake fluid replacement and timing chain or belt service history if applicable to this engine variant. On the test drive, listen for any irregular engine noises, hesitation or warning light illumination following the November 2025 MIL defect, and ensure the engine management lamp behaves correctly during the ignition on and running phases. A scan of the engine control unit for stored fault codes would also be prudent given the recent MIL failure.
