2016 Mercedes-Benz C 2.1L Diesel · PO66 XFP

The vehicle most recently passed its MOT on 7 October 2025, with a single advisory noting that the nearside rear tyre was worn close to the legal limit and worn on the edge. Looking at the broader DVSA history, the maintenance trend is broadly stable but does show a few points worth attention. The car passed cleanly in 2020, 2023, and 2024, but the 2022 test accumulated advisories relating to front and rear brake discs being lipped and worn, along with rear brake pads noted as wearing thin. A dangerous failure in November 2024 related to an offside front tyre defect (bulge due to structural separation) was evidently remedied, as the car passed the same day following repair. A prior dangerous failure in September 2020 concerned inoperative offside rear stop lamps. While the pattern does not indicate a deteriorating mechanical condition, the brake and tyre wear items are recurring themes that warrant close physical inspection prior to purchase. With recorded mileage of 23,017 miles against an approximate age of ten years, this C-Class has covered only around 2,300 miles annually, which is markedly low. Such low usage typically implies either short, infrequent journeys or extended periods of standing, both of which have specific mechanical consequences. Prolonged standing can lead to corrosion on brake discs (visible as surface rust that may or may not clear with use), binding or seized brake calipers, degradation of brake fluid due to moisture absorption, and weakening of the 12V battery through repeated shallow discharge cycles. Equally, low-mileage vehicles can suffer from oil seal drying out, leading to unexpected leaks once regular use resumes, and from perishing of rubber components such as tyres, drive belts, and suspension bushes that age regardless of mileage. Given the advisories regarding brake disc wear and lipping recorded in 2021 and 2022, a careful inspection of the braking system is essential. On a test drive, listen for any grinding, squealing, or pulsation through the brake pedal, and check whether the vehicle pulls to one side under braking, which could indicate a binding caliper. Visually inspect the discs for a pronounced lip on the outer edge, deep scoring, or significant corrosion pitting, and assess pad material thickness directly. The tyre advisories, including the recent nearside rear edge wear and the 2024 dangerous failure, suggest that wheel alignment should be verified; uneven wear patterns can point to worn suspension bushes, droplinks, or track rod ends. With ten years of calendar ageing on the tyres regardless of mileage, check the sidewalls and tread for cracking, perishing, or hardening of the rubber compound, particularly on any tyres that may have been fitted for many years. Beyond the braking system and tyres, the low annual mileage profile demands attention to several time-based service items. Verify the brake fluid replacement interval, as moisture absorption degrades performance over time irrespective of use. Inspect the coolant for condition and strength, and confirm the timing of the most recent cambelt or chain service according to Mercedes-Benz schedules, as age-based wear is more relevant than mileage for this component. Examine the underbody and suspension arms for surface corrosion consistent with age, particularly around mounting points, and check the exhaust system for any rust-through at joints or hangers. Finally, confirm full Mercedes-Benz or specialist main dealer service history stamps in the service book, as a low-mileage premium vehicle of this age benefits considerably from documented care to preserve structural integrity, drivetrain longevity, and resale value.
