2017 Mercedes-Benz A-Class 2.1L Diesel · SC06 ANY

The most recent DVSA MOT test on the 2017 Mercedes-Benz A-Class was conducted on 2025-08-29, resulting in a pass. However, this follows a pattern of recurring advisories and one major failure, suggesting that while the vehicle has not failed the MOT outright in the last two years, underlying mechanical issues persist. The 2025 test alone recorded two advisories—one concerning the near-side front lower suspension arm ball joint showing slight play and another on the offside front tyre nearing its legal wear limit—indicating that these problems have not been fully resolved. The prior failure in August 2025 due to a non-functional near-side side repeater light further highlights a trend where critical components or systems may be degrading or failing intermittently. The 2024 test showed only minor advisories, suggesting a brief period of stability, but the overall maintenance history remains inconsistent, with advisories and failures recurring at regular intervals. The vehicle’s recorded mileage of 63,479 miles at the time of this assessment represents a reasonable annual usage rate of approximately 7,053 miles per year, which is typical for a nine-year-old car driven under normal conditions. The consistency of mileage accumulation over the years suggests a steady, moderate driving profile rather than extreme wear from either light use or heavy, high-mileage driving. However, the lack of a service history or recorded long periods of inactivity means that certain consumables and components may have experienced accelerated wear due to sustained use rather than intermittent stress. The suspension ball joint and tyre wear advisories, in particular, could be influenced by this usage pattern, as both are prone to gradual deterioration from repeated loading and movement. Given the recurring advisories on the near-side front lower suspension arm ball joint and the offside front tyre wear, the prospective buyer should conduct a thorough inspection of the suspension system. During a test drive, listen for unusual clunking or rattling noises from the front suspension, particularly when the vehicle is driven over bumps or at higher speeds, as this may indicate further play or wear in the ball joint. Visually inspect the suspension arms and bushings for signs of excessive wear, oil staining, or separation, and check for uneven tyre wear patterns, which could suggest misalignment or suspension misalignment. The near-side front tyre’s proximity to the legal tread limit necessitates immediate replacement, as the dangerous failure in 2023 underscores the criticality of this issue. The offside front tyre’s edge wear may also warrant closer inspection for potential internal damage or structural compromise. Additionally, the failed brake pads in 2021 and the subsequent near-side rear brake pad wear advisory in 2024 suggest that the braking system requires attention. During a test drive, pay close attention to brake pedal travel, feel, and response, checking for sponginess, excessive pedal travel, or a grinding noise, which could indicate worn brake pads, warped discs, or fluid issues. Inspect the brake discs for signs of corrosion, binding, or uneven wear, particularly on the near-side rear and offside front areas. The side repeater light failure in 2025 also indicates a potential electrical or wiring issue that should be addressed to ensure proper vehicle signalling. For the tyre advisories, the buyer should replace the near-side front tyre immediately to avoid a repeat MOT failure, and consider replacing the offside front tyre as soon as possible to prevent further wear or safety risks. Beyond these immediate concerns, the vehicle’s age and mileage warrant a comprehensive service check, including fluid top-ups, filter replacements, and a check of the 12V battery health, as standing vehicles can lead to corrosion or degradation in these components over time. Finally, examine the tyres for sidewall perishing or cracking, which can compromise structural integrity, and verify that the vehicle has been serviced according to the manufacturer’s schedule, as the lack of recorded service history may indicate missed maintenance opportunities.
