2017 Smart (mcc) Fortwo 1.0L Petrol · BV17 AAE

Recurring issues with exhaust emissions and tyre degradation define the recent mechanical profile of this vehicle, culminating in a failure during the 28 August 2026 test. The most recent inspection recorded a failure due to an exhaust Lambda reading outside specified limits and an inoperative engine malfunction indicator lamp, alongside an advisory for a minor exhaust gas leak. This follows a pattern of increasing advisories regarding perishing or cracking tyres, which have appeared in multiple consecutive tests since 2024. While the vehicle passed on 28 August 2026, the combination of emission failures and persistent tyre condition issues suggests a recent shift from the clean records seen in 2021 and 2022 towards more frequent component-related defects. The recorded mileage of 42,178 miles over approximately nine years represents an average annual accumulation of roughly 4,686 miles. This low annual mileage is consistent with a vehicle that has seen limited use, which can often lead to the specific types of degradation noted in the MOT history. Specifically, the repeated advisories for tyres cracking or perishing are common in vehicles that undergo infrequent use, as rubber compounds can degrade from age and lack of movement rather than tread wear. This usage pattern necessitates a close inspection of all rubber components and seals that may have become brittle due to extended periods of inactivity. Prospective buyers should pay close attention to the engine management and exhaust system following the recent major failures. During a test drive, listen for any unusual engine idling, hesitation under acceleration, or audible changes in exhaust note that might indicate the reported minor leak or issues with the Lambda sensor and emission control. It is also vital to verify that the engine malfunction indicator lamp (MIL) operates correctly when the ignition is switched on, as the failure of this lamp was a specific reason for the 2026 test failure. Any intermittent engine warning lights or changes in exhaust smell should be treated as significant indicators of unresolved emission issues. Suspension and tyre integrity also require physical verification. The 2025 records highlighted worn front suspension arm pins or bushes on both the nearside and offside, so a test drive should include monitoring for knocks, clunks, or imprecise steering response when navigating uneven surfaces or turning the wheel at low speeds. Furthermore, despite the recent pass, the persistent advisories for perishing tyres across multiple axles suggest that the rubber may be reaching the end of its serviceable life regardless of tread depth. Inspect the sidewalls of all tyres for deep cracks and ensure there is no visible bulging or uneven wear that could compromise handling.
