2020 Mercedes-Benz GLC 1.9L Diesel · OO11 DUN

Recurring brake system wear and suspension component deterioration define the mechanical profile of this vehicle, with the most recent test on 23 February 2026 showing a pattern of thinning pads and pitted or scored discs across both front and rear axles. While the vehicle passed its latest inspection, the advisory history indicates a persistent trend of brake component degradation that has been noted in three of the last four annual tests. This pattern of advisories for worn discs and pads, combined with a major failure in February 2025 regarding excessively worn front lower suspension arm ball joints, suggests that consumable components and steering linkages are subject to regular wear. The recorded mileage of 70,805 miles over approximately six years represents an average annual accumulation of roughly 11,800 miles, which is consistent with typical UK usage for a vehicle of this age. This steady mileage profile suggests the vehicle has been in regular use rather than sitting stationary for extended periods, which aligns with the observed wear on the braking system and tyres. Mechanically, this level of usage typically correlates with the gradual depletion of suspension bushes and the progressive thinning of brake friction materials, both of which are reflected in the documented MOT history. A prospective buyer should pay close attention to the braking performance during a test drive, specifically looking for any pedal judder or vibration when applying pressure at higher speeds, which can indicate the pitted or scored discs noted in the 2026 advisory. Given the previous major failure of the nearside and offside front lower suspension arm ball joints, it is essential to listen for any knocking, clunking, or creaking sounds when navigating uneven road surfaces or turning the steering wheel at low speeds. Any wandering or a tendency for the vehicle to pull to one side during straight-line driving could indicate that the suspension components or tyres have not been adequately addressed following previous advisories. Further inspection of the tyre condition is necessary, as the 2025 records flagged both front tyres as being worn close to the legal limit or worn on the edges. This can be a symptom of incorrect wheel alignment or excessive wear from the previously flagged suspension issues. The buyer should also verify if the front windscreen wiper blade, which was noted as defective in the February 2026 test, has been replaced, and ensure that the undertrays and covers mentioned in 2023 are not currently obstructing a clear view of the chassis or underside components during a physical inspection.
