2018 Mercedes-Benz A-Class 1.5L Diesel · BW67 NSF

A recent MOT episode revealed that the windscreen’s swept area was obstructed and the nearside rear tyre was close to the legal limit, prompting an initial failure that was rectified before the car was re‑tested and passed on the same day; the pass now carries advisories for front and rear brake discs showing wear, pitting or scoring but not yet deemed unsafe. Apart from that incident, the record is otherwise clean, with no recorded failures since 2020 and only tyre‑wear advisories appearing in the last two years, indicating a generally stable roadworthiness trend that has only begun to show wear on high‑use components. At 80,344 mi spread over roughly eight years the average annual mileage sits around 10,000 mi, which aligns with typical usage for a vehicle of this age and class. The MOT history shows regular annual testing with no significant gaps, suggesting the odometer reading is credible and the car has not experienced prolonged periods of inactivity that could conceal hidden deterioration. This mileage level places the vehicle into a regime where consumables such as brake discs, tyres and suspension bushings are expected to be approaching the latter stages of their service lives. When inspecting the brakes, pay particular attention to any pulsation through the pedal, squealing or grinding noises when applying pressure, and visual signs of surface pitting on the discs. Measuring disc thickness against the manufacturer’s minimum specification will confirm whether replacement is imminent. Given the advisories, a thorough check of the brake pads for uneven wear and the caliper mounting points for any play is advisable. For the tyres, examine the nearside rear and front tyres for cuts, bulges, or uneven tread wear that could indicate underlying alignment or suspension issues; a nail‑puncture previously noted may have been repaired, but residual damage can lead to sidewall weakness. Verify tyre pressure retention and listen for any thumping that could betray a concealed puncture. Finally, confirm that the windscreen area directly in the driver’s line of sight is free of cracks, chips or heavy deposits that could re‑create the obstruction flagged in the recent MOT. While the MOT does not record structural or suspension faults, a sensible test‑drive should include a feel for any steering pull, excessive body roll or clunking over bumps, which could hint at worn bushes or mounting points that have not yet manifested as MOT defects. Addressing the brake disc wear and ensuring the tyres are within legal limits will be the primary tasks before the car can be considered reliably roadworthy for continued use.
