2014 Mercedes-Benz A-Class 1.5L Diesel · WF14 XNU

A pattern of age‑related suspension wear dominates the MOT record, highlighted by a major failure for an excessively worn near‑side front anti‑roll bar linkage ball joint in the most recent test (29 May 2026) and a prior major failure for a fractured off‑side rear coil spring (25 June 2025). These serious defects sit alongside recurring advisories for front and rear brake discs showing wear, pitting or scoring, and a series of tyre condition advisories over the past few years, indicating that the vehicle’s structural and braking components have required attention more frequently than the routine pass‑only entries of 2024‑2026 would suggest. At 65,103 mi the car averages roughly 5,400 mi per annum, well below the typical usage for a 2014 model. The low annual mileage points to relatively light use or periods of inactivity, which can mitigate wear on drivetrain and engine parts but does not preclude the development of fatigue‑type failures in suspension components that are more age‑dependent. The MOT history shows no large gaps in testing, with annual checks from 2021 onward, confirming that the vehicle has been regularly inspected despite its modest mileage. When evaluating the suspension, pay particular attention to the front anti‑roll bar linkage on the near‑side; any clunking or looseness when cornering, a vague knocking over bumps, or uneven steering response may signal the worn ball joint noted in the latest MOT. The off‑side rear coil spring should be inspected for cracks, broken coils or abnormal movement, and the surrounding mounting points checked for corrosion or cracked bushings. A thorough visual and tactile inspection of all suspension bushes, control arms and subframe welds is advisable, as age‑related fatigue can progress rapidly once a primary component has failed. The brake discs, flagged repeatedly for scoring, should be measured for remaining thickness and examined for deep grooves that could affect braking efficiency; feel for pedal pulsation or a juddering sensation under moderate braking, which often accompanies disc surface irregularities. Tyre condition advisories across all four wheels suggest the need for a detailed tyre inspection—look for sidewall cracks, tread edge damage and uneven wear patterns that may indicate alignment or suspension issues. The minor windscreen damage recorded does not affect visibility but should be assessed for any potential for future cracking. Budget for replacement of the anti‑roll bar linkage, rear coil spring (if still compromised), brake discs and possibly the tyre set to restore the vehicle to a reliable road‑worthy state.
