2018 Mercedes-Benz C 2.0L Petrol · C4 NCH

The most recent DVSA MOT test for this 2018 Mercedes-Benz C-Class, conducted on 29 May 2026, resulted in a pass with a single advisory note regarding an offside rear tyre exhibiting superficial damage. Reviewing the broader test history, the vehicle has maintained an unbroken sequence of passes since first presentation in this dataset, with no recorded failures or dangerous defects. The advisories are minor and predominantly relate to routine wear items rather than systemic mechanical deterioration. The maintenance trend can therefore be characterised as stable and consistent, suggesting that the vehicle has been subjected to regular inspection and that any wear-related issues have been addressed promptly. The recurring nature of the rear brake pad advisory in 2022 and 2023, followed by clean tests in 2024 and 2025, indicates that the braking system has been attended to appropriately within the wear progression, which is a positive indicator of conscientious upkeep. With 51,404 miles recorded over an eight-year period, this C-Class has covered approximately 6,426 miles annually, which broadly aligns with typical usage for a vehicle of this age and class. There are no significant gaps in the mileage progression between MOT tests, suggesting continuous rather than sporadic use, which is generally beneficial for mechanical longevity as it mitigates issues associated with prolonged standing such as brake disc corrosion, seal drying, and battery degradation. This moderate annual mileage means that major drivetrain and engine components are unlikely to have sustained excessive wear, though consumable items including brake discs, tyres, and suspension bushes will still require periodic attention due to natural aging of materials regardless of mileage accumulation. For a prospective buyer, the recurring advisory regarding rear brake pad wear across the 2022 and 2023 tests warrants confirmation that the pads were subsequently renewed, and attention should be directed towards the corresponding brake discs. On inspection, the rear discs should be checked for lipping, scoring, or corrosion pitting, particularly given that the more recent advisories have ceased, suggesting possible renewed components. During a test drive, listen for any grinding or scraping noises from the rear axle, observe for any pulling under braking, and check the electronic parking brake for smooth operation without warning lights on the instrument cluster. Additionally, verify the condition and age of the front brake components, which by mileage and time should now be approaching a service interval, and inspect all visible brake lines and flexible hoses for any perishing or fluid seepage. The 2026 advisory noting a cut on the offside rear tyre should prompt a thorough physical inspection of all four tyres for sidewall cracking or perishing, which is common on vehicles of this age regardless of tread depth. Check the date codes on the tyre sidewalls to ensure none are excessively aged, and examine the rear nearside tyre for matching wear patterns. Beyond the recorded MOT items, this 2018 vehicle should be evaluated for age-related concerns including the condition of the 12V auxiliary battery, which typically requires renewal every five to seven years and may present starting difficulties or electronic glitches if weakened. All major fluid services including engine coolant, brake fluid, and transmission oil should be verified as recently performed according to manufacturer schedules, as these degrade over time independently of mileage. Finally, inspect the underbody and exhaust system for any surface corrosion, examine suspension components including control arm bushes and coil springs for any signs of deterioration, and ensure all electronic systems including the infotainment unit, sensors, and driver assistance features are functioning correctly, as complex Mercedes systems can develop faults with age.
