2018 Smart (mcc) Forfour 1.0L Petrol · RF68 VCC

The vehicle passed its most recent MOT in December 2025, but this came immediately after a failure the previous day due to a serious exhaust gas leak and emissions readings outside specified limits. With 109,727 miles recorded, this Smart Forfour has covered significantly higher mileage than average for its age, accumulating roughly 13,700 miles per year. The history reveals a concerning pattern involving the wheels and tyres. In 2024, the tester noted a distorted inner road wheel, which suggests a past impact with a pothole or kerb. By late 2025, this appeared to escalate to a damaged inner sidewall on the nearside front tyre. Inner sidewall damage is particularly risky as it can lead to sudden blowouts, and combined with the previous wheel distortion, it strongly hints at underlying suspension damage or misalignment. The December 2025 failure also flagged a major exhaust gas leak and Lambda readings outside specified limits. While the car passed the next day, indicating a repair was carried out, you should verify if this was a temporary patch or a comprehensive fix, as Lambda sensor issues can point to deeper engine management problems. The condition trend appears to be worsening. The vehicle had a clean bill of health in 2023, but the last two years have introduced structural wheel issues and significant engine exhaust defects.
