2017 Audi A3 2.0L Petrol · AJ66 FMP

A history of clean roadworthiness defines this vehicle, following a period of mechanical instability regarding exhaust emissions in early 2023. While the car failed its MOT on 1 March 2023 due to major issues with carbon monoxide levels and incorrect Lambda readings alongside a minor exhaust gas leak, the subsequent tests have shown no recorded defects. The most recent pass on 18 November 2025 confirms that the emissions-related failures were addressed, establishing a trend of successful compliance over the last two years. The recorded mileage of 61,877 miles over approximately nine years equates to an average annual accumulation of roughly 6,875 miles. This usage pattern is consistent with typical light-to-moderate driving rather than high-frequency motorway use or excessive short-trip urban cycles. From a mechanical perspective, this level of mileage suggests that while primary drivetrain components may not have reached high-wear thresholds, consumables such as brake pads, discs, and suspension bushes should still be assessed for age-related degradation rather than purely mileage-based exhaustion. Given the specific failure recorded in March 2023, a prospective buyer should pay close attention to the engine's idling stability and exhaust performance. Although the 2025 tests show no defects, it is prudent to monitor for any changes in exhaust note or scent during a test drive. Listen for any unevenness in the engine idle or any sudden changes in acceleration that could indicate the emissions control systems or oxygen sensors are not maintaining the correct air-fuel ratio. The advisory regarding a minor exhaust gas leak in 2023 indicates that the central exhaust pipework was previously compromised. During a physical inspection or test drive, check for any abnormal vibrations or loud droning noises coming from beneath the vehicle, particularly when accelerating. While the recent clean records suggest this was rectified, ensuring there is no audible hissing or visible soot staining around the exhaust manifold and pipe connections is a necessary step to confirm the integrity of the exhaust system.
