2016 Ford Focus 2.3L Petrol · D12 OAP

A recurring issue with exhaust emissions levels defined the vehicle's recent testing history, specifically regarding excessive carbon monoxide content at both idle and fast idle. This pattern of failure was evident in July 2025, where two separate tests within a week both resulted in major failures due to these emissions exceeding manufacturer and default limits. While the vehicle has since returned to a clean status with a pass recorded on 02 June 2026 and no defects noted, the recent volatility in exhaust gas composition is the primary mechanical feature of this record. The vehicle has covered 54,828 miles over its ten-year lifespan, which equates to an average annual accumulation of approximately 5,483 miles. This represents a low-mileage usage profile for a 2016 Ford Focus. Mechanically, such low annual mileage can sometimes result in less frequent operation of certain engine components or exhaust after-treatment systems, which may correlate with the emissions failures observed in mid-2025. However, the lack of significant mileage increases between tests suggests the vehicle is used for relatively short-distance or infrequent journeys. Given the specific history of carbon monoxide failures, a prospective buyer should pay close attention to engine performance and idling stability. During a test drive, listen for any unevenness in the engine note while stationary or any hesitation during acceleration, which could indicate issues with the fuel-air mixture or sensor performance. Although the most recent test on 02 June 2026 showed no defects, the previous failures suggest that the combustion efficiency was compromised; therefore, verifying that the engine reaches operating temperature smoothly and maintains a steady idle is essential. Beyond the emissions history, the low mileage means that while drivetrain wear may be lower than average, other components like suspension bushes or tyres may have aged due to time rather than distance. While no specific structural or suspension defects were flagged in the provided records, the recent emissions issues are the only documented mechanical concern. Focus the inspection on ensuring the engine responds linearly to throttle inputs and that there are no signs of smoke from the exhaust, which would be relevant following the recorded failures.
