2017 Mercedes-Benz A-Class 1.5L Diesel · EU67 UML

Brake-related wear is the recurring theme in this Mercedes-Benz A-Class's MOT history, with the front axle drawing particular attention from testers over the recorded period. The vehicle passed its most recent test on 11 June 2025 with no advisories recorded, indicating that the immediate roadworthiness status at the time of test was sound, yet this clean result sits alongside an earlier pattern of brake and tyre concerns. On 6 May 2022 the car failed on dangerous and major criteria for front brake pad wear, with pads down to less than 1.5 mm and recorded as worn to the wear indicator; the same test included advisories for front brake disc wear along with edge wear on both front tyres at 3 mm and 4 mm respectively. The subsequent 2024 test repeated a nearside front tyre edge-wear advisory, and a separate dangerous failure on 12 August 2020 identified structural bulges on both offside tyres. Taken together, the record suggests a vehicle that has passed its tests consistently but has shown a tendency towards front-end component consumption rather than any structural or systemic mechanical deterioration. With 66,789 miles accumulated over nine years, the A-Class is running at roughly 7,421 miles annually, a rate broadly typical for its age and one that points to regular rather than intermittent use. There are no multi-year gaps in testing that would suggest extended periods off the road, and the mileage progression between tests is consistent with annual MOT cycle usage, indicating the odometer has been turning over steadily. This kind of usage pattern tends to produce predictable wear on consumables such as brake pads, discs, tyres, and ancillary rubber components, rather than the corrosion and fluid degradation that can affect vehicles left standing for long periods. The data therefore supports a view of normal mechanical cycling without extremes either of overwork or neglect through disuse. For a prospective buyer, the front braking system warrants direct and specific attention on any inspection. Given the 2022 failure for pad wear down to the indicator and the advisory for disc wear at that test, the front discs and pads should be physically examined for current thickness, with attention paid to the inner edges where pad wear often progresses first on this axle configuration. On a test drive, listen for any scraping or grinding from the front corners under light braking, feel for pedal pulsation that would point to disc runout or lipping, and note any pulling to one side under firm stops which could indicate a binding caliper or uneven pad transfer. The 2024 advisory for nearside front tyre edge wear suggests a tracking or alignment consideration, so verify that the steering returns cleanly to centre after cornering and that the vehicle does not tramline or drift over uneven cambers. The tyre history is the second area of focus, given the dangerous structural bulges recorded in 2020 and the recurring edge-wear advisories on the front pair. Inspect all four tyres for bulges, cracks in the sidewalls, and uneven shoulder wear, paying particular attention to whether the front tyres are wearing on the inner or outer edges as this will dictate whether a four-wheel alignment is overdue. Suspension condition should also be assessed through a road test, listening for clonks or knocks from the front struts, top mounts, and anti-roll bar linkages over speed humps and broken surfaces, as well as feeling for any vagueness in steering response that could indicate worn tie rod ends or drop links. Finally, ensure the engine covers and under trays noted as fitted in 2022, 2023, and 2024 are removed during any pre-purchase inspection so that oil leaks from the sump, power steering rack, and front subframe mounting points can be properly assessed without obstruction.
