2022 Mercedes-Benz A 200 AMG Line ED Executive A 1.3L Petrol · LL22 WDK

The most recent DVSA MOT on 17 June 2026 resulted in a failure, the failure being recorded as “Dangerous – Rear Inner brake pad(s) less than 1.5 mm thick”. The test also carried advisories for front and rear brake discs showing wear, pitting or scoring, and an off‑side rear tyre close to the legal tread limit. Compared with the 30 June 2025 MOT, which was passed but already flagged thin rear pads and worn discs, the defect profile has progressed from advisory‑only to a dangerous condition, indicating a clear deterioration in the braking system rather than a stable or improving maintenance trend. At 53 328 miles the car is roughly four years old, giving an average annual mileage of about 13 300 mi. This is considerably above the typical UK average of 8‑10 000 mi per year for a premium executive model and suggests a relatively high level of component utilisation. The accelerated mileage accumulation will have accelerated wear on consumables such as brake discs, pads, tyres and suspension bushings, and may also have placed additional strain on the drivetrain and engine oil life, especially if the vehicle has been used for frequent high‑speed or spirited driving. The immediate priority for a prospective buyer is the braking system. The rear inner pad thickness below 1.5 mm is a safety‑critical condition and the pads will need to be replaced promptly, together with a thorough inspection of the rear caliper for uneven wear, sticking or fluid leakage. The front and rear discs, already noted as pitted and scored, should be measured for minimum thickness and resurfaced or replaced if they are approaching the wear limit, as disc scoring can lead to brake pulsation, reduced stopping power and increased pad wear. On a test drive, listen for any squeal or grinding, feel for a soft or spongy pedal, and check for any vibration under braking, particularly on the rear axle. The off‑side rear tyre is at the legal tread minimum and should be replaced without delay; examine the remaining tyres for sidewall cracking, age‑related perishing and consistent wear patterns that could reveal alignment or suspension issues. Beyond the brakes, the high mileage warrants a comprehensive inspection of the suspension and steering components. Check the condition of the front and rear suspension bushes, ball joints and tie‑rod ends for any signs of looseness, clunking or uneven tyre wear, which would indicate bush wear or misalignment. Verify the state of the 12 V battery, especially its cranking amperage and electrolyte level, as age‑related degradation is common after four years. Inspect all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – for correct levels, colour and any signs of contamination; fluids should be changed on a calendar basis even if mileage is low. Finally, request the full service book to confirm that scheduled services, particularly brake fluid flushes and tyre rotations, have been performed in line with Mercedes‑Benz recommendations, as a well‑documented service history can mitigate some of the wear concerns highlighted by the MOT record.
