2017 Mercedes-Benz C220 D AMG Line Auto 2.1L Heavy oil · AF17 HSV

With four consecutive MOT tests between March 2022 and February 2026 all returning pass results and no advisories of any kind on file, the official roadworthiness record for this C220 D AMG Line is entirely clean. There are no recorded brake, suspension, tyre, exhaust, corrosion, or lighting advisories, and no failures or refusals at any point. For a nine-year-old Mercedes-Benz diesel covering significant mileage, the absence of any flagged items is unusual and noteworthy, suggesting that either wear-related defects have not yet reached MOT failure thresholds or that minor issues have been remedied before each annual test. The most recent examination on 16 February 2026 confirms a clean pass, and the unbroken sequence of clean passes demonstrates a stable rather than improving or worsening trend across the four-year testing window. The recorded mileage of 139,805 against a 2017 registration equates to an annual accumulation of roughly 15,534 miles, which is high for the vehicle's age and places it firmly in above-average use territory. There is no gap in annual testing that would suggest a prolonged period off the road, so the high mileage figure represents continuous, sustained operation rather than a sudden jump or a long lay-up followed by recommissioning. Mechanically, this level of sustained mileage on a Mercedes-Benz C-Class diesel means that the engine, automatic transmission, turbocharger, dual-mass flywheel, injectors, and EGR components will have done substantially more work than a typical example of the same age. Consumables such as brake discs, pads, and tyres, along with suspension components including control arm bushes, springs, and shock absorbers, will have experienced proportionally greater wear, even if the MOT record does not yet formally flag any of these items. Given the high annual mileage and the age of the vehicle, particular attention should be paid during inspection and test drive to the common wear points of the W205 C-Class diesel. On a road test, listen for any knocking or clonking from the front suspension over uneven ground, particularly indicative of worn lower control arm bushes, anti-roll bar links, or top mounts, and feel for vagueness or play in the steering. Check for any pulling to one side under braking, which could suggest binding calipers or unevenly worn discs, and feel for pedal pulsation indicating warped front discs. With high mileage on the OM654 diesel unit, listen for any rattle on cold start from the timing chain area, watch the exhaust for excessive smoke particularly under load which could indicate turbo or injector wear, and check for any oil seepage around the engine and transmission sump. Inspect the underside carefully for corrosion on subframe mounting points, brake pipes, and fuel lines, as the absence of MOT advisories does not rule out developing surface corrosion that has not yet been flagged. The condition of the tyres, brake pads, and discs visible on the day of inspection will be a strong indicator of remaining service life given this usage pattern, and any uneven wear across the axles would suggest alignment or suspension issues that have not yet appeared in the MOT record. Confirm that the AdBlue system is functioning correctly and that there are no warning lights relating to emissions or the diesel particulate filter, as these are common fault areas on high-mileage Mercedes-Benz diesels and would not necessarily appear as MOT advisories. Finally, verify the service history independently through main dealer or specialist records, as the clean MOT file alone does not confirm whether major items including automatic transmission fluid changes, timing belt replacement if applicable, and injector balancing have been carried out at the correct intervals for this level of annual use.
