2020 MG ZS 1.0L Petrol · CU20 OFD

The vehicle currently holds a valid MOT certificate following a clean pass on 10 June 2026 at 48,145 miles. The maintenance trajectory shows clear improvement after repeated emissions failures earlier this year. The tester recorded excessive exhaust carbon monoxide readings at both idle and fast idle during the 27 May 2026 test, yet the same inspection criteria passed without remark just two weeks later. This rapid resolution indicates the previous owner addressed the underlying fault promptly rather than ignoring it. The absence of any further advisories or defects confirms the car meets current roadworthiness standards. Recorded mileage sits at 48,145 miles against an approximate six-year age, averaging roughly 8,000 miles per annum. This usage profile aligns with standard private driving patterns and suggests moderate engine and drivetrain loading. The testing interval remains consistent, with annual examinations spanning from July 2024 through June 2026. Two consecutive failure notices in mid-2025 and early 2026 highlight a concentrated period where emissions calibration drifted before corrective work restored compliance. No extended standing periods appear evident within the log, which typically preserves suspension bushings and brake components from moisture-related degradation. Buyers should verify the exhaust management system under operating temperature before finalising the purchase. The repeated carbon monoxide exceedances point to a rich running condition, often caused by a failing lambda sensor, degraded catalytic converter efficiency, or faulty fuel pressure regulation. Request a live data scan to confirm oxygen sensor switching frequencies and long-term fuel trims remain within manufacturer specifications. Inspect the nearside front dipped beam circuitry for corroded connectors or damaged bulb holders, as the July 2025 failure required immediate electrical attention. A brief road test will confirm stable idle characteristics and rule out intermittent misfires that could trigger secondary emissions warnings.
