2008 Subaru Forester 2.0L Petrol · PX08 DGZ

The most critical issue with this vehicle is the significant gap in testing history. The last valid MOT certificate expired on 18 December 2021, meaning this Subaru has been off the road for nearly five years as of today. A long period of inactivity is often more damaging to a vehicle than high mileage, particularly for rubber components, brakes, and fluids. Looking at the available history, the mechanical trend appeared to be worsening between 2019 and 2021. The 2019 test was clean, but the 2020 and 2021 entries both recorded a failure for the offside rear fog lamp, indicating a persistent electrical fault that was ignored or difficult to rectify. By the 2021 test, a new and more serious defect emerged regarding exhaust carbon monoxide content exceeding default limits. This suggests the engine was running rich, which can point to issues with oxygen sensors, the air filter, or fuel injectors. The recorded mileage of 158,283 is roughly typical for an 18-year-old car, averaging about 8,800 miles per year. However, the lack of mileage accumulation since 2021 implies the vehicle has been standing stationary for a long period. While the drivetrain may have been rested, seals can dry out and corrosion can set in.
