2015 Mercedes-Benz A-Class 2.1L Diesel · X121 ABY

The vehicle presents a mixed maintenance profile with a recent trend toward worsening mechanical advisories. While the most recent MOT on 12 November 2025 at 55,687 miles resulted in a pass, the record shows a failure just two days prior at 55,681 miles. That failure was triggered by a fractured offside rear coil spring, which was subsequently rectified to secure the pass. However, the tester flagged significant wear and pitting on both front and rear brake discs as advisories during the successful test, indicating that while the car is currently roadworthy, the braking system is approaching the end of its service life. The mileage accumulation is notably low for an eleven-year-old vehicle, averaging approximately 5,062 miles per year. The data shows consistent, gradual increases in mileage, such as the 3,907-mile rise between the October 2024 test and the November 2025 test. This low-use pattern often suggests the vehicle has been used for short journeys or has spent significant periods stationary. While this reduces wear on the drivetrain, it can contribute to the surface corrosion and pitting seen on the brake discs, as components may not be subjected to frequent, high-temperature friction to clear surface oxidation. A prospective buyer must prioritise a physical inspection of the braking system. The recurring advisories for pitted and scored discs across the front and rear axles suggest that a full brake overhaul, including new discs and pads, will be required shortly. The previous failure involving a fractured coil spring also warrants a close examination of the entire suspension assembly, specifically checking for other perished bushes or damaged springs that may have been overlooked. The history also shows a minor lapse in basic upkeep during the October 2020 test, where the vehicle failed on tyre tread depth and a faulty windscreen wiper. Although these are consumable items, they indicate a period where routine maintenance was neglected. Given the current advisories, the buyer should verify the condition of all tyres and ensure the recent suspension repairs were carried out to a professional standard to prevent further structural or handling issues.
