2017 Mercedes-Benz E 1.9L Diesel · SN67 MOU

A pattern of front suspension and brake wear emerges as the defining mechanical story for this 2017 Mercedes-Benz E-Class. The most recent test on 29 November 2025 passed with only a minor stone chip note on the windscreen, which on the surface suggests a stable tail-end picture, but the broader history tells a more revealing story. In December 2023 the nearside front lower suspension arm ball joint was deemed excessively worn and recorded as a Major defect causing failure, alongside advisories for both front brake pads wearing thin. By December 2024 the front pads were no longer flagged, but both front brake discs were noted as pitted or scored (though not seriously weakened), and both rear tyres were close to the legal limit and worn on the edge. A failed attempt the same day was down solely to an insufficient washer fluid level, an easily rectified driver item rather than a mechanical defect, and the same brake and tyre advisories were carried across to the subsequent pass. The presence of a suspension ball joint Major failure does temper the otherwise pass-heavy record, and the recurrence of brake-related advisories across consecutive tests indicates a component family that is steadily consuming wear margin. Annual mileage of roughly 8,049 miles sits broadly in line with what would be expected for a nine-year-old executive saloon, so there is no glaringly low or high accumulation to flag. The recorded odometer readings progress consistently from year to year with no unusual gaps or jumps, suggesting continuous rather than sporadic use. Mechanically, this steady but moderate rate of travel implies that wear components have been subjected to normal cumulative use rather than the accelerated degradation that heavy mileage inflicts, but it also means the vehicle has not benefited from the thorough warm-up cycles and extended running that help keep seals, dampers, and complex suspension geometry from drying out or seizing. The 2023 suspension failure should be read against this usage level; a ball joint reaching Major wear status at moderate mileage on a 2017 chassis points to either a component that has aged beyond its designed fatigue life or a previous repair that has since settled into wear. For a prospective buyer, the front suspension and brake assemblies should be the focus of any physical inspection. With a documented Major failure on the nearside front lower arm ball joint, the entire front suspension geometry warrants close scrutiny: jack the vehicle and check for play in both lower arm joints, listen for clonking or knocking over speed bumps and uneven road surfaces, and pay particular attention to any vagueness or knocking through the steering wheel when turning. Inspect the bushes in the control arms, anti-roll bar drop links, and the condition of the front coil springs for any signs of cracking or sagging, as these wear alongside ball joints on E-Class chassis of this age. The 2024 advisory for both front brake discs being pitted or scored means the discs have measurable surface deterioration; on a test drive expect to feel any brake judder or vibration through the steering wheel under firm application, and check that the pedal feels firm and progressive rather than spongy, as binding calipers are common on cars that have sat with marginal brake components. The rear tyre edge wear recorded in late 2024 is a secondary but worthwhile clue, as uneven shoulder wear typically traces back to suspension geometry, camber settings, or alignment issues rather than inflation alone. Before purchase, confirm when the rear tyres were actually replaced and whether a four-wheel alignment has been carried out, particularly in light of the prior front suspension repair, because a renewed ball joint without a geometry check can leave residual tracking problems that chew into rear tyre shoulders. Verify that the windscreen washer system now functions correctly and that the fluid reservoir is filled, as this minor item caused a failure in 2024. Beyond the flagged components, inspect the underside of the vehicle, paying close attention to the front subframe mounting points, brake pipe routing along the chassis rails, and the condition of the exhaust hangers and mounts, all of which are common corrosion and fatigue points on E-Class saloons approaching a decade of service. Finally, request evidence of what work was carried out following the 2023 ball joint failure, as the quality of that repair directly governs whether the 2025 clean pass represents sustained mechanical health or simply a recently rectified issue that could resurface.
