2009 Audi A4 1.8L Petrol · NG09 JOD

The vehicle remains roadworthy but the maintenance history shows a worsening trend regarding structural integrity and recurring suspension wear. The most recent test in December 2025 at 108,018 miles flagged persistent play in the offside front lower suspension arm ball joint and a worn offside rear inner tyre. While the vehicle passed the test, the persistence of central rear sub-frame corrosion, which has been noted in every annual test since 2021, indicates an ongoing process of oxidation that has not been addressed with preventative treatment. At 17 years old, the recorded mileage of 108,018 represents a low annual average of approximately 6,354 miles. This low usage is consistent across the vehicle's life, though there is a notable gap in records between 2016 and 2018 where the car likely sat stationary. Since 2019, the mileage accumulation has remained steady at roughly 7,000 miles per year. The low mileage suggests that the vehicle is likely subject to age-related degradation of rubber components and metalwork rather than mechanical fatigue from high mileage. A buyer must prioritize a physical inspection of the central rear sub-frame to determine if the corrosion has progressed beyond surface level, as the tester has repeatedly noted it as not seriously weakened for five consecutive years. The offside front lower suspension arm ball joint requires replacement as it was flagged in both 2023 and 2025, suggesting the previous owner failed to rectify the fault. Additionally, the frequent mention of manufacturer body and engine covers restricting the tester's ability to see critical underside components means a manual thorough check for hidden fluid leaks or structural rust in the engine bay and chassis is essential.
