2007 Toyota Yaris 1.4L Diesel · NA07 OTS

The most recent MOT on 2025-10-13 recorded a pass with two notable issues: nearside front brake pipe corrosion (covered in grease or material) and general underbody surface corrosion . These align with recurring corrosion problems seen in earlier MOTs, suggesting ongoing exposure to environmental or maintenance factors. The vehicle’s age (19 years) and mileage (149,287 miles) place it in a typical range for its age, averaging ~7,857 miles annually. This suggests neither extreme under-use nor heavy wear, though mileage alone cannot confirm usage patterns. A major failure in the 2025-10-10 MOT revealed structural corrosion in the nearside rear suspension mounting, missing exhaust heat shields , incorrect headlamp alignment , brake pipe corrosion , brake fluctuation , and excessive emissions . These issues indicate significant wear in critical safety systems, including braking, lighting, and exhaust integrity. The same period also showed brake disc wear and suspension bush degradation , which were previously noted in 2024 MOTs. While some issues were addressed by 2025, the persistence of corrosion and brake-related defects suggests a worsening trend in mechanical reliability. Recurring problems include underbody corrosion (noted in 2025, 2024, and 2023), brake component wear (discs, pipes, and fluctuating brakes), and suspension bush degradation . These issues are not isolated but reflect systemic vulnerabilities in the vehicle’s aging structure and braking system.
