2017 Mercedes-Benz A-Class 2.1L Diesel · GD66 JJL

The vehicle is currently roadworthy following a clean pass in February 2026, but the recent history reveals a period of reactive maintenance rather than proactive care. The failure in January 2026 at 113,735 miles is concerning as it flagged multiple safety-critical defects including exposed cords on the nearside tyre, illegal tread depth on the offside, and an engine MIL malfunction. While these issues were rectified for the subsequent test weeks later, the pattern suggests the owner only addresses mechanical faults when they result in an imminent MOT failure. At 113,737 miles over nine years, this A-Class has covered an average of 12,637 miles per annum, which sits above the national average for its age. The data shows a significant surge in usage between January 2023 and January 2024, where 13,432 miles recorded, followed by another 7,408 miles in the following year. This high mileage puts accelerated strain on the drivetrain and suspension components, which is consistent with the recurring issues noted with tyres and steering hardware found in the record. A buyer must conduct a thorough inspection of the front suspension geometry, as the record previously flagged a damaged track rod end ball joint dust cover in 2024. The engine management system failure in early 2026 is a significant red flag that requires a diagnostic scan to ensure the underlying sensor fault was not simply cleared rather than repaired. Given the history of lighting-related MOT failures, verify that the headlamps are properly aligned and functional, as the vehicle has repeatedly struggled with lens defects and aim issues across multiple years.
