2018 Mercedes-Benz C 2.1L Diesel · FV67 HVT

The most recent MOT test on this 2018 Mercedes-Benz C-Class, conducted on 12 February 2026, resulted in a pass with no defects or advisories recorded, which represents a clean and reassuring outcome at the point of test. However, when reviewing the trajectory of the past four examinations, a clear pattern emerges in which tyre wear advisories have been issued at every test from 2023 through 2025, before clearing up in early 2026. While the absence of recorded defects at the latest assessment is encouraging, prospective buyers should treat the recurring edge wear as evidence of an underlying issue, most likely geometry misalignment, worn suspension components, or perhaps a driving style that promotes shoulder wear. The 2023 test additionally flagged slight play in both front lower suspension arm ball joints, a defect that warrants close attention as such joints tend to deteriorate progressively and can be a precursor to more significant suspension failure if left unaddressed. With 155,498 miles recorded over approximately eight years of service, this C-Class is accumulating mileage at a rate of around 19,437 miles annually, which is notably higher than the national average for a vehicle of this age. This sustained level of motoring means that consumable items such as brake pads, discs, tyres, and clutch components will have been subjected to considerable wear, and the drivetrain including the transmission, turbocharger, and engine ancillaries will have covered substantial ground. The MOT history shows no significant gaps in mileage progression, indicating the vehicle has been in regular use rather than left standing for extended periods, which is generally favourable for mechanical health but does mean the buyer should anticipate that many wear-and-tear components may now be approaching the threshold for replacement. For a prospective buyer, the most pressing area to investigate is the suspension system, particularly the front lower wishbones and ball joints referenced in the 2023 advisory. On a test drive, listen carefully for any clonking or knocking noises when traversing speed bumps or uneven road surfaces, and pay attention to vague or wandering steering response, which can indicate worn bushes or perished mounting components. Inspect the inner and outer edges of the tyres for uneven wear patterns such as feathering, cupping, or excessive shoulder wear, as the recurring edge wear advisories suggest the tracking or suspension geometry may still require correction. It would also be prudent to have the vehicle raised on a ramp for a thorough inspection of the front suspension arms, anti-roll bar links, and drop links, as these are common replacement items on high-mileage Mercedes-Benz chassis. Beyond the recorded advisories, the high annual mileage dictates that several age- and use-related service items deserve verification before purchase. Confirm that the automatic transmission fluid and filter have been changed at the manufacturer-recommended intervals, as neglected gearbox servicing on high-mileage Mercedes vehicles can lead to harsh shifting and torque converter issues. Inspect the brake discs for lipping and check that the calipers are sliding freely without binding, which is a known concern on vehicles that see frequent stop-start driving. Examine the condition of the timing chain or belt according to the service schedule, verify the cooling system for signs of corrosion or weeping from the water pump and expansion tank, and ensure the 12-volt battery is in good health, as modern Mercedes-Benz vehicles are particularly sensitive to voltage irregularities. Finally, request a full service history to corroborate that all time-based servicing such as brake fluid renewal, coolant replacement, and spark plug changes have been carried out in line with the manufacturer's requirements.
