2009 Subaru Impreza 2.5L Petrol · VN09 PPK

The vehicle is currently roadworthy following a pass in October 2025, but the maintenance trend shows a recent decline in mechanical efficiency and emissions compliance. The failure on 17 October 2025 at 94,503 miles revealed significant issues with the exhaust system, including high carbon monoxide levels, lambda sensor failures, and a physical leak. While the car passed just one week later at 94,598 miles, the persistence of a noisy exhaust suggests the underlying fault may have been only partially addressed rather than fully rectified. At 17 years old, the recorded 94,598 miles represents relatively low annual usage, averaging approximately 5,565 miles per year. The data shows a notable gap in testing between August 2023 and October 2025, where the vehicle covered only 7,048 miles over two years. This low-frequency use often correlates with age-related degradation of rubber components and seals, despite the low mileage. The 2022 advisory for front tyres worn on the edge indicates that basic alignment or tire pressure checks were occasionally neglected during these intervals. A buyer must prioritise inspecting the exhaust system and engine management components. The recent failure for emissions and lambda readings suggests the catalytic converter or oxygen sensors may be nearing the end of their life or leading to costly repairs. The physical inspection should also verify that the nearside headlamp levelling sensor was replaced after being flagged as broken in the previous test. Given the vehicle's age and low mileage profile, a thorough check for structural corrosion on the sills and suspension mounting points is essential, as these models are prone to hidden rust when they sit for long periods.
