2016 Skoda Citigo 1.0L Petrol · WM65 LRK

The most recent MOT test on the 2016 Škoda Citigo recorded a failure due to persistent exhaust emissions faults, with the vehicle’s lambda sensor and carbon monoxide/hydrocarbon readings outside the permissible limits during fast idle testing. This marks a significant deviation from the vehicle’s previous MOT history, where the majority of tests passed with only minor advisories—particularly around tyre wear and brake pad thickness—indicating a stable maintenance profile until this point. The failure suggests either a failure in the exhaust system’s catalytic converter or sensor calibration, potentially exacerbated by prolonged standing or infrequent use, which can lead to carbon buildup or sensor degradation. While the 2024 and 2025 MOTs also flagged tyre perishing, the current emissions failure is a critical major defect that must be addressed immediately, as it directly impacts emissions compliance and long-term environmental and regulatory adherence. The vehicle’s recorded mileage of 40,348 miles over roughly ten years represents an annual average of around 4,035 miles, which is notably lower than the industry average for a similarly aged car, particularly one of this model’s age and performance characteristics. Such low mileage can stem from either minimal operational use or prolonged periods of inactivity, both of which introduce distinct mechanical considerations. Extended standing can accelerate corrosion in brake systems, particularly on the rear discs and calipers, where rust may cause binding or reduced braking efficiency. Additionally, static conditions can lead to fluid degradation in the cooling system, hydraulic brakes, and power steering, as moisture and contaminants can accelerate wear without the dynamic dilution provided by regular driving. Conversely, if the vehicle has been driven infrequently, the suspension components, such as coil springs and suspension bushes, may not have experienced the typical wear progression associated with high-mileage use, but they could still suffer from dry friction or premature failure if not serviced regularly. For a prospective buyer, the most urgent concern is the recent MOT failure related to exhaust emissions, which requires immediate rectification to avoid further legal and environmental issues. Prior to proceeding with purchase, the buyer should verify the cause of the emissions failure—whether it stems from a faulty lambda sensor, a failing catalytic converter, or an exhaust leak—and confirm that the repair has been completed to the manufacturer’s specifications. During a test drive, listen for unusual exhaust noises, such as a rough idle or backpressure, which may indicate exhaust system issues. Additionally, check for any visible leaks around the exhaust manifold or catalytic converter, and ensure the vehicle meets current emissions standards post-repair. Beyond the emissions concern, the vehicle’s tyre history presents a recurring advisory that demands attention. The repeated advisories of tyres worn close to legal limits or showing edge wear suggest either uneven tyre pressure or alignment issues, which can lead to premature wear and compromise handling. The perishing of rear tyres noted in previous MOTs highlights the need for a thorough visual inspection of the tyre sidewalls for cracks or delamination, as this can indicate underlying structural weakness. Inspect the tyre tread depth and ensure the vehicle is fitted with tyres that meet the manufacturer’s recommendations for load and speed ratings. For the brakes, given the thinness of the front pads noted in the 2025 MOT, a visual inspection of the brake discs and linings is essential, with particular attention to signs of glazing, warping, or excessive heat damage, which can reduce braking performance. Finally, since the vehicle’s usage profile suggests low annual mileage, the buyer should prioritise checking the battery health, as prolonged standing can lead to sulphation or reduced capacity, and verify that all fluids—including coolant, brake fluid, and power steering fluid—are within their service life, as these can degrade over time even without significant mileage.
