2018 Mercedes-Benz E 1.9L Diesel · WD67 HCL

A pattern of recurring tyre wear and isolated emissions or lighting defects defines the MOT history of this 2018 Mercedes-Benz E-Class, with the most recent test on 21 October 2025 recording a clean pass and no advisories, suggesting a stabilising roadworthiness picture heading into the latest certificate. Across seven recorded tests since 2021, two failures have appeared: a nearside headlamp aim defect on 9 June 2023 and an engine MIL inoperative fault on 28 November 2024, the latter accompanied by advisories on both front and rear tyres and front brake discs. The fact that the 2024 failure was followed by a same-day pass with identical tyre and disc advisories but no recorded MIL issue implies a likely repair or reset of the engine management system between the two examinations. Front brake disc wear on both sides has been flagged at the 2024 test, and consistent all-round tyre wear advisories across 2023 and 2024 point to a vehicle that has been working its consumables at a steady rate, though no corrosion, suspension, or structural defects have been recorded to date. At 75,905 miles over approximately eight years, this E-Class is averaging close to 9,500 miles annually, which sits broadly in line with typical UK usage for a vehicle of this age and class. There are no significant gaps in the MOT record that would imply extended off-road periods, and the progression between tests suggests regular rather than sporadic use. This level of mileage on a Mercedes of this generation is not unusual and means that wear items such as brake discs, pads, tyres, and likely suspension components will have seen multiple replacements by now, although the absence of any recorded suspension or underbody advisories suggests no obvious structural concerns have yet surfaced at test. The steady accumulation rate also implies the engine and drivetrain have been worked consistently, which can be preferable to very low annual mileages where seals, gaskets, and oil may deteriorate through standing rather than running. Given the specific components flagged, a prospective buyer should pay particular attention to the braking system on a test drive, as front brake disc wear was noted on both sides at the 2024 test. Listen for any knocking or scraping when pulling away at low speed, feel for any vibration or pulsing through the brake pedal under firm application, and check whether the car pulls to one side under braking, which could indicate uneven pad wear or a binding caliper. The tyres should be inspected for uneven shoulder wear across both axles, as the repeated edge-wear advisories on all four corners suggest either alignment geometry that is marginally out of specification or habitual use on lightly loaded journeys that does not allow the tyres to scrub evenly across their full width. The 2023 headlamp aim failure and the 2024 MIL fault are both items that can recur if not addressed at their root cause, so they warrant specific verification before purchase. Confirm that both headlamps are now correctly adjusted by checking the beam pattern against a flat wall in the dark, ideally with the vehicle loaded normally rather than on its own. For the engine management light, request evidence of any diagnostic work undertaken following the November 2024 failure, as intermittent MIL illumination on a Mercedes-Benz of this era can stem from sensor issues such as a failing lambda probe, mass airflow sensor, or crankcase ventilation faults, and a reappearance under load or after warm-up would warrant a pre-purchase diagnostic scan. Finally, given that no structural or corrosion advisories have appeared across the entire recorded history, a careful underside inspection on a ramp remains worthwhile to verify the absence of any emerging rust on subframes, brake lines, or suspension arms that may not yet have reached the threshold for an MOT advisory.
