2017 Mercedes-Benz A-Class 1.5L Diesel · SA67 DKK

A recurring theme in the MOT history is progressive brake wear, with advisories appearing on both front and rear discs and pads from 2022 onward and culminating in thin rear pads and corroded disc edges in the latest 2025 test. The vehicle has consistently passed the annual test, but the pattern shows a steady deterioration of the braking system rather than an isolated fault, suggesting that component replacement will be required in the near term. The lone failure in 2022 was unrelated to the brakes, being limited to an off‑side headlamp aim issue that was corrected for subsequent tests. At 75,992 mi recorded over roughly nine years the average annual mileage is about 8,400 mi, which sits comfortably within typical UK usage for a compact executive car. The MOTs have been logged annually with no significant gaps, indicating the mileage figure is likely accurate and the vehicle has not experienced prolonged periods of inactivity that could conceal hidden deterioration. This moderate mileage implies that wear on consumables such as tyres, brakes and suspension components will be in line with normal expectations for a car of this age. When inspecting the brakes, feel for any pedal pulsation or sponginess and listen for squeal or grinding under light to moderate braking, which would confirm the thin rear pads and the heavily lipped front disc are approaching the end of their service life. Examine the disc surfaces for deep scoring, rust patches extending beyond the edges, and check that the pads engage evenly on both sides; uneven wear may indicate caliper binding that should be verified. Given the tyre advisories from 2024 and 2021, inspect the tread depth on all four wheels, look for sidewall cuts or bulges, and note any vibration at higher speeds that could point to a developing imbalance or internal tyre damage. Finally, verify the headlamp alignment by observing the illumination pattern on a flat surface; an aim that remains too high could cause glare to other road users and may require adjustment. While no suspension or structural advisories appear in the record, a brief road‑test should include listening for clunks over bumps and checking that the steering remains steady without pull, as worn bushings can emerge between MOTs. Addressing the brake and tyre wear now will mitigate the risk of unexpected failure and preserve the vehicle’s roadworthiness for the next MOT cycle.
