2018 Mercedes-Benz C 2.1L Diesel · MB18 AEB

A pattern of tyre degradation has defined the mechanical history of this 2018 Mercedes-Benz C-Class, with cracking and perishing advisories appearing on virtually every test over the past four years and one outright failure recorded in February 2024 when a nearside rear tyre sustained a cut deep enough to reach the internal cords. The most recent examination on 5 February 2026 returned a pass, but the same offside front and offside rear tyre perishing advisories from 2025 resurfaced unchanged, indicating that the rubber compound continues to deteriorate despite a clean bill of health overall. The remaining advisories across the record are isolated rather than chronic, comprising a single instance of front brake pad wear in February 2024, a one-off nearside rear tyre edge wear note from March 2021, and a single suspension ball joint play advisory from February 2025. There are no recorded advisories relating to corrosion, exhaust integrity, fluid leaks, lighting, or structural components, and aside from the 2024 tyre-related failure, the vehicle has passed every test presented. With an odometer reading of 33,565 miles over an eight-year registration period, this C-Class has accumulated roughly 4,200 miles annually, which is notably low for its age and points towards either extended periods of inactivity or predominantly short, low-load journeys. The MOT test dates themselves confirm a consistent pattern of annual use rather than any prolonged lay-up, with tests conducted every February or March from 2021 onwards and no multi-year gaps in the roadworthiness record. Mechanically, such low annual mileage tends to preserve major drivetrain components but can accelerate degradation of items that suffer from prolonged standing, including tyre sidewalls becoming brittle from UV exposure and oxidation, brake discs developing surface corrosion, and under-bodies becoming susceptible to moisture trapping. The recurring tyre cracking advisories align directly with this usage profile and represent the clearest mechanical signature of the vehicle's history. For a prospective buyer, the priority during inspection should be a thorough tyre assessment, as the four-year pattern of perishing across multiple axle positions indicates the rubber is likely to require a full replacement set regardless of remaining tread depth. Each tyre should be examined closely for sidewall crazing, cracking between the tread blocks, and any bulging or deformation, particularly on the offside front and offside rear positions where advisories have repeatedly appeared. The front suspension ball joint flagged in February 2025 warrants specific attention on the test drive; listen for clonking or knocking noises from the front end when traversing speed bumps or uneven surfaces, and feel for any vagueness or looseness in the steering response, particularly during low-speed direction changes. The 2024 front brake pad advisory also requires confirmation that the pads have since been renewed, and on the road any pedal pulsation, grinding sounds, or pulling to one side under braking would warrant immediate investigation of the discs and caliper operation. Given the low mileage, the brake discs themselves should be inspected for severe surface rust pitting, as prolonged low-speed use combined with infrequent heavy braking can leave the braking surface unevenly corroded despite acceptable pad wear.
