2014 Mercedes-Benz A-Class 2.1L Diesel · KAZ 4019

Recurring braking issues and a pattern of electrical and lighting failures define the recent mechanical profile of this Mercedes-Benz A-Class, with the latest test on 15 May 2026 showing a pass alongside multiple advisories. A persistent advisory for the offside rear service brake fluctuating has appeared in every MOT record since May 2024, indicating a long-term, unresolved issue with the rear braking system. This trend is accompanied by more recent advisories regarding thinning front and rear brake pads and a TPMS light being active, suggesting that consumable wear is currently a primary concern. The vehicle has covered 58,314 miles over its twelve-year lifespan, which equates to an average annual usage of approximately 4,860 miles. This is significantly lower than the UK national average, suggesting the car has been used for short trips or has spent considerable periods stationary. While lower mileage generally implies less wear on high-mileage components like the engine and gearbox, such low annual accumulation can sometimes lead to more frequent issues with components that rely on regular movement, such as braking systems and electrical sensors. A physical inspection and test drive must prioritise the recurring offside rear brake fluctuation. During the drive, pay close attention to any pulsing or vibration felt through the brake pedal or the chassis when applying the rear brakes, which could indicate a sticking caliper or a warped disc. Given the recent advisory for thinning pads on both the front and rear axles, the thickness of the remaining friction material should be measured, and the condition of the brake discs should be checked for scoring or excessive lip formation. The active TPMS light also requires investigation to determine if it is caused by a faulty sensor, a slow puncture, or a system fault. Further attention should be directed toward the suspension and lighting components mentioned in previous failures. Although the fractured offside rear coil spring noted in May 2024 was rectified to achieve a pass, the suspension should be inspected for any signs of uneven wear or noise. Listen for knocks or clunks when driving over uneven surfaces, which could indicate that other suspension bushes or dampers are beginning to fail. Finally, verify that the side repeaters and headlamp aim are functioning correctly to ensure the electrical and lighting defects that caused previous failures have been fully addressed.
