2016 Subaru ST 2.5L Petrol · AD65 WCV

The vehicle remains in a state of marginal roadworthiness with a worsening trend regarding exhaust integrity. While it passed the February 2024 test at 76,188 miles, the record shows a failure to resolve significant mechanical issues from the previous year. The tester flagged a noisy exhaust and a gas leak at the central rear exhaust box, which followed high carbon monoxide readings in 2023. This suggests the previous owner opted for reactive repairs to pass the MOT rather than addressing the underlying engine efficiency or exhaust system degradation. At 76,188 miles, the Subaru has averaged approximately 7,600 miles per year, which aligns with typical annual usage for a decade-old vehicle. There is a 5,642-mile gap between the May 2023 failure and the February 2024 pass, indicating consistent use rather than long periods of standing. However, the low annual mileage does not appear to have prevented mechanical wear, as the recurring emissions failures suggest the engine may be struggling with combustion issues despite the low distance covered. A buyer must conduct a thorough inspection of the exhaust system to ensure the minor leak noted in 2024 was properly rectified and is not a recurring symptom of internal manifold corrosion. The high carbon monoxide levels from 2023 necessitate a check of the oxygen sensors, spark plugs, and catalytic converter health. Additionally, the previous issues with headlamp aim and rear reflectors indicate a history of neglected minor-item maintenance, so a full check of all lighting components and the structural integrity of the rear exhaust assembly is essential before purchase.
