2016 Mercedes-Benz C 2.1L Diesel · WD16 FDG

The most recent DVSA examination on 3 July 2025 returned a Pass, accompanied by a single advisory concerning the rear brake discs showing wear, pitting or scoring, though not to a degree considered seriously weakened. Looking back through the recorded MOT history, the vehicle has demonstrated a consistently stable maintenance profile with no failures or refusals on record, and indeed has passed every test cleanly since 2020. The advisory history does, however, show a repeating theme of brake disc wear appearing across multiple tests, alongside recurring near-side rear tyre wear advisories in 2019, 2023 and 2024. This suggests a pattern of attention to consumables rather than any worsening structural concern, and the overall trend should be regarded as steady and properly maintained. The recorded mileage of 57,267 miles across approximately ten years equates to an annual average of around 5,727 miles, which is notably low for a vehicle of this age and segment. Such modest usage typically indicates either predominantly short urban journeys or extended periods of standing between uses. Either scenario carries mechanical implications. Low-mileage cars are prone to brake disc corrosion and binding calipers from inactivity, time-related perishing of tyres, degradation of brake fluid through moisture absorption, and 12V battery failure from sustained standing. The diesel or petrol powerplant, depending on specification, will also benefit from regular extended running to maintain emissions system efficiency and oil condition, so short-trip use should be considered when planning future servicing intervals. Given the recurring rear brake disc advisories, a prospective buyer should physically inspect both rear discs for lipping, surface corrosion, and any visible scoring that may now have progressed beyond the advisory threshold. The handbrake should be tested on an incline to confirm caliper function, and the test drive should be conducted with deliberate, firm brake applications from higher speeds to detect any shudder, vibration through the pedal, or pulling to one side that would indicate disc warping or a seizing caliper. Equally, the front discs received an advisory in early 2022 for similar pitting, and although no further advisory has appeared, they too merit a close visual inspection for corrosion between braking surfaces. The near-side rear tyre edge wear noted on three separate occasions points to a possible tracking misalignment or worn rear suspension geometry, so a four-wheel alignment check is advisable, particularly as cumulative wear can accelerate if left uncorrected. Beyond the recorded advisories, the age and low mileage of this Mercedes-Benz C-Class warrant several standing-related inspections. All four tyres, including the spare if fitted, should be examined for sidewall perishing and cracking, as rubber degrades with time irrespective of tread depth, and any tyre over six years old should be replaced as a matter of course. The 12V battery should be load-tested, as low-mileage use and prolonged standing frequently lead to premature failure; a weak battery can also produce erratic electronic behaviour across the vehicle's control systems. Brake fluid and coolant should be considered due for renewal on calendar age rather than mileage, with brake fluid particularly susceptible to moisture ingress over a ten-year period. Finally, confirmation of a complete main dealer or specialist service history is strongly recommended, as low annual mileage can mask missed servicing intervals, and verification of cambelt or timing chain replacement intervals, along with recent oil and filter changes, will provide further reassurance regarding the long-term mechanical integrity of this vehicle.
