2019 MG ZS 1.0L Petrol · NH19 XEB

The vehicle is currently roadworthy, but the most recent inspection indicates a sudden decline in maintenance consistency. While the car passed its tests between 2022 and 2024 without defects, the September 2025 test at 45,682 miles revealed three distinct points of concern. The failure due to high carbon monoxide emissions and an oil leak, followed by a pass after repairs suggests the engine health or management system may require attention, marking a worsening trend compared to previous clean records. The mileage pattern remains consistent with a low-use profile, averaging approximately 6,500 miles per year. Between July 2022 (26,254 miles) and July 2024 (37,769 miles), the vehicle covered 11,515 miles, showing steady usage. The jump of 7,913 miles leading to the September 2025 test follows this trajectory. This low mileage generally preserves drivetrain and suspension components but can sometimes lead to the degradation of rubber seals and gaskets if the vehicle sits for extended periods. A buyer must perform a close inspection of the engine bay to identify the source of the oil leak flagged in 2025. Although the tester noted the leak was not excessive, persistent weeping can indicate failing valve cover gaskets or oil seals that will eventually worsen. The previous carbon monoxide failure necessitates a check of the exhaust system, oxygen sensors, and spark plugs to ensure the engine is burning fuel efficiently. You should also verify that the offside windscreen wiper blade was replaced as per the failure report to ensure visibility is not.
