2017 Mercedes-Benz C 2.1L Diesel · FD17 EBJ

A 2017 Mercedes-Benz C-Class presenting a broadly clean roadworthiness record over the past four years, with the most recent test on 2026-02-07 passing without advisories, mirroring identical clean passes on 2025-02-22 and 2024-02-19. The single failure on 2024-02-19 was confined to headlamp aim being set too low on both front lamps, a straightforward adjustment rather than a mechanical defect, and the vehicle passed on the same day once rectified. The earlier failure on 2023-02-10 is more concerning in context because it related to dangerous rear tyre tread depth below the 1.6 mm legal minimum on both rear tyres, although the subsequent test three days later passed with only advisories. Across the eight tests recorded since 2021, there has been one dangerous failure and one minor failure, giving a generally stable but not unblemished picture of compliance. Recorded mileage stands at 77,783 miles over approximately nine years, equating to an average annual accumulation of around 8,643 miles, which sits close to the typical usage rate for a vehicle of this age. There are no significant gaps in the annual testing pattern, with tests consistently recorded in February of each year from 2021 through 2026, indicating the car has remained in regular use on public roads rather than being laid up. Mileage progression between consecutive tests appears steady, suggesting consistent everyday driving rather than periods of heavy touring followed by extended standing. At this kind of annual mileage, consumable wear on tyres, brake components and suspension linkages is proportionate rather than accelerated, but age-related deterioration of rubber and underbody components still warrants scrutiny given the vehicle is now in its tenth year. Targeted inspection effort should concentrate on the components flagged in the 2023 advisories. The near-side front tyre was noted as slightly perished and worn close to the legal limit on the outer edge, with the offside front tyre showing identical perishing and outer-edge wear. Outer-edge tyre wear typically points to either chronic under-inflation, worn suspension bushes allowing excessive camber, or a tracking issue, and this is worth a close look at the condition of the front control arm bushes, top mount bearings, and a current geometry check. The offside front brake disc was also flagged as worn in 2023, so on a test drive any brake judder through the pedal, pulsing under heavy braking, or a grinding sensation from the front axle would warrant further investigation into the current disc and pad condition, as discs that were marginal at the last recorded MOT may now require replacement. The rear tyres that failed dangerously in February 2023 highlight the importance of checking the current tread depth on all four corners as a priority, together with inspecting the sidewalls for any cracking or perishing consistent with the front tyres flagged in the same period. Because the headlamp aim failure was present on both sides in 2024, it is worth verifying that both front lamps are correctly aligned and that any aftermarket bulb or housing replacement has not altered the beam pattern. During a road test, particular attention should be paid to steering self-centring and straight-line stability given the front tyre wear pattern, any knocking or clonking from the front suspension over uneven surfaces, and the effectiveness of the brakes without pulling to either side. A raised inspection on a ramp would also be sensible to examine the underside for corrosion on subframe and suspension components, which tends to develop progressively on vehicles of this age regardless of MOT history.
