2009 Toyota Yaris 1.3L Petrol · AF09 OBM

The most recent MOT test conducted on the 2009 Toyota Yaris on 2026-02-03 resulted in a failure, with persistent issues persisting from the prior test date, indicating no meaningful improvement in maintenance or defect resolution. The vehicle’s MOT history reveals a pattern of recurring problems, particularly with the front brake system and engine-related faults, which have consistently led to failures despite some passing tests. The presence of multiple advisories—such as corroded brake pipes, deteriorated drive shaft boots, and thin brake pads—suggests either inadequate maintenance or underlying wear that has not been addressed proactively. This trend raises concerns about the vehicle’s long-term reliability, as repeated failures often point to systemic issues that may escalate without intervention. The recorded mileage of 80,761 miles for a vehicle aged approximately 17 years represents a relatively low annual usage rate of around 4,751 miles per year, which is unusually low for its age. Such low mileage can result from infrequent use, long periods of inactivity, or deliberate underutilisation, which may contribute to accelerated wear from standing corrosion, fluid degradation, and component deterioration. However, the absence of higher mileage accumulation does not necessarily mean the vehicle is well-maintained; instead, it may highlight neglect in consumable replacements and preventative servicing. For example, standing corrosion on brake pipes and components can worsen over time, even without active use, while fluids like brake fluid and engine coolant degrade with age regardless of mileage. Given the recurring MOT failures and advisories, the buyer should prioritise a thorough mechanical inspection to assess the severity and progression of the identified issues. Start by examining the front brake system for signs of corrosion beyond what was noted in the MOT, including the brake pipes, hoses, and calipers for binding or excessive play. Listen for unusual noises during braking, such as grinding or squeaking, which may indicate worn pads or warped discs. The corroded brake pipes should be inspected for structural integrity; if they are severely compromised, replacement may be necessary to prevent leaks or failure under braking. Additionally, the constant velocity joint boot failure suggests ongoing issues with the drivetrain, so check for leaks around the joint, excessive play when turning, or whining noises during acceleration or cornering. For the engine-related MIL (Malfunction Indicator Light) faults, which have appeared in multiple MOTs, the buyer should verify the vehicle’s electrical system, including the wiring harness, sensors, and fuel system components. Listen for any misfire symptoms, such as rough idling or hesitation during acceleration, and check for exhaust emissions for unusual smells or backpressure, which may indicate a broader engine issue. If the MIL persists despite previous repairs, further diagnostic testing may be required to pinpoint the exact cause, such as a faulty oxygen sensor, spark plug, or fuel injector. Given the low mileage, the vehicle’s fluids—particularly brake fluid, engine coolant, and transmission fluid—should be checked for degradation, as standing fluids can become contaminated or lose effectiveness over time. Finally, the offside headlamp aim issue from the 2024 MOT should be addressed to ensure compliance with legal standards, as improper aim can affect visibility and safety. If the buyer proceeds with purchase, they should budget for immediate repairs to resolve the brake system and engine faults, as these are critical for roadworthiness and long-term reliability.
