2012 Mercedes A-Class 2.0L Diesel · KY62 WFW

The most recent MOT, conducted on 15 April 2026 at 95,102 miles, resulted in a pass, but the advisory list reveals a braking system in clear decline. The tester flagged both front and rear brake discs as worn, noted excessive travel on the handbrake lever, and recorded the rear service brake as only just meeting minimum performance requirements. This combination points to a worsening maintenance trend. While the car passed its previous three tests cleanly, the sudden appearance of multiple braking faults at the latest inspection suggests components have reached the end of their serviceable life without timely replacement. The mileage record shows a steady and typical accumulation of approximately 6,800 miles per year for a 2012 vehicle. The interval between the December 2023 test at 71,877 miles and the April 2024 test at 77,760 miles indicates around 5,883 miles covered in just over four months, followed by a slower build to 87,735 miles by April 2025 and then to 95,102 miles by April 2026. There are no suspicious gaps or sudden drops in recorded mileage, and the progression is consistent with regular daily use rather than long periods of inactivity. A buyer should focus their physical inspection on the braking system as a priority. The worn front and rear discs flagged in April 2026, combined with the handbrake lever travel issue, mean pads and discs are likely due for replacement, and the handbrake mechanism itself may need adjustment or cable replacement. The rear calipers should be checked for binding, which can cause uneven disc wear and the performance deficit noted during the test. The April 2024 failure for worn tyres on both rear wheels also warrants attention to the rear suspension geometry. Misalignment or worn rear suspension bushes could be causing the uneven tyre wear pattern recorded then, and if left uncorrected, it will continue to destroy rubber prematurely. Beyond the brakes, the front oil leak advisory from the most recent test deserves a close look under the bonnet and beneath the engine. Even if deemed not excessive at the time of test, oil leaks on a Mercedes of this age commonly stem from degraded cam cover gaskets or crankshaft seals and can worsen rapidly. A thorough underbody inspection for corrosion is also advisable, as the A-Class platform from this era is susceptible to rust around the rear subframe mounts and sills, particularly if the car has spent time standing during any ownership gaps.
