2018 Mercedes-Benz C 2.1L Diesel · BX53 AJS

The vehicle most recently passed its MOT on 16 April 2026 with no defects or advisories recorded, continuing a run of three successive passes in 2024, 2025 and 2026 without any items raised. This is a strong indicator of stable maintenance, as the absence of any defects, advisories or monitoring items across the three most recent tests suggests that any previously flagged wear items have been addressed or have not yet progressed to a reportable state. However, the single advisory-laden test in March 2023, where brake disc condition and a rear tyre were noted, demonstrates that the braking system and tyres were already on the radar and warrant continued scrutiny, particularly given the higher-than-average annual mileage. Overall, the maintenance trend appears stable and presently well managed, but it would be prudent to investigate the resolution status of the 2023 advisories through service records or direct inspection. With 98,010 miles recorded over approximately eight years, the vehicle is covering around 12,251 miles annually, which sits well above the typical UK average of 7,000 to 9,000 miles per year. This elevated usage rate accelerates wear on all consumables and mechanical components, including brake pads and discs, tyres, suspension bushes, coil springs, drivetrain mounts and the dual-mass flywheel if fitted. There are no significant mileage gaps evident in the test history, with annual tests showing consistent progression and no evidence of long periods of standing. Higher mileage examples of this model require more frequent servicing intervals to remain reliable, so verifying a fully stamped service book with Mercedes-Benz or specialist intervals, ideally corroborated by Mercedes-Benz digital service records, will be essential to confirm diligent maintenance. Although the most recent MOT was entirely clean, the advisories raised in 2023 are particularly relevant to this higher-mileage example. The rear and front brake disc advisories indicating pitting and scoring on both sides suggest that corrosion has been forming on the disc surfaces, and at this mileage the discs are likely approaching or already at the manufacturer wear limit, with brake pads typically requiring replacement concurrently. On a test drive, listen for any brake shudder under firm pedal application, grinding noises, or vibration through the pedal, and check for pulling to one side under braking which could indicate a binding caliper. The offside rear tyre worn on edge advisory could point to a suspension geometry issue, such as worn rear trailing arm bushes or a failing shock absorber, so a road test should be used to detect any clonking noises from the rear suspension over speed bumps or uneven road surfaces, alongside a visual check for uneven shoulder wear across all four tyres. Beyond the documented MOT items, a prospective purchase should conduct a thorough physical inspection given the vehicle's age and accumulated mileage. Tyre sidewalls should be examined carefully for perishing and cracking from age, even if tread depth is satisfactory, as eight-year-old original tyres may require replacement on age grounds alone. Given the consistent year-on-year use, the 12V battery is likely still active and reasonably healthy, but a load test would confirm its state. All brake calipers and flexible hoses should be inspected for seepage and corrosion, as higher-mileage Mercedes-Benz vehicles are known for seized slider pins that can accelerate uneven pad wear. Time-based servicing items should also be verified regardless of mileage intervals, including engine oil and filter, brake fluid replacement typically biennially, coolant renewal, transmission fluid if automatic, and the condition of the ancillary drive belts and tensioners. A compression or cylinder leak-down test would be worthwhile given the mileage, and a diagnostic scan for any stored fault codes in the engine, transmission and restraint control modules would help identify latent issues not surfaced during MOT testing.
