2012 Mercedes-Benz C 2.1L Diesel · EO12 PLF

A clean and unblemished DVSA roadworthiness record is the defining feature of this 2012 Mercedes-Benz C-Class, with the most recent assessment on 17 May 2025 passing without a single advisory or defect being recorded. That result is consistent with the previous four tests, all of which returned clean passes dating back to 2022. The single failure logged on 25 May 2024 was also recorded with no defects, indicating a likely administrative or retest event rather than a genuine mechanical non-compliance, and the vehicle passed cleanly when retested on the same day. Across five years of testing there is no evidence of recurring advisories relating to suspension components, brake pipe corrosion, subframe integrity, or any other items that typically surface on a chassis of this age. This unbroken sequence of defect-free outcomes suggests the vehicle has remained structurally and mechanically sound throughout its documented testing life. With 100,493 miles accumulated over fourteen years, this C-Class is running at an average of roughly 7,178 miles per year, a figure that sits squarely within the normal bracket for a car of its age and original market positioning. There are no extended gaps in the MOT history, no periods of unrecorded activity, and no sudden mileage jumps between tests that would suggest clock irregularities or a dormant vehicle brought back into service. Mechanical wear on a car driven at this steady, moderate rate tends to be progressive and evenly distributed, meaning consumables such as brake pads, discs, tyres, and fluid services should have been replaced at predictable intervals rather than suffering the accelerated degradation seen on high-mileage or stop-start urban use vehicles. The drivetrain, being a Mercedes unit, is generally well-proven at this mileage point, but it remains advisable to verify the service book and confirm that the cambelt or timing chain, whichever is fitted, has been renewed within the manufacturer's specified window. For a prospective buyer, the absence of flagged components in the MOT record means attention should shift to the general mechanical condition of items that commonly affect a W204-generation C-Class once it reaches six-figure mileage. On a test drive, listen for any clonking or knocking from the front suspension over uneven surfaces, as the front lower wishbone arms and anti-roll bar drop links are known wear items and would not necessarily have been flagged unless play was excessive at the time of test. Similarly, monitor for any knocking or vibration through the steering, which can point to top mount or steering linkage wear. The braking system should feel firm and progressive underfoot; any pulling to one side under braking, a soft or spongy pedal, or grinding noises would warrant inspection of the discs, pads, and possibly a binding caliper. Given the engine is now well into its working life, a thorough inspection of the cooling system is sensible, particularly the condition of the radiator, expansion tank, and coolant hoses, as plastic components on this generation can become brittle with age. Check for any signs of oil misting or seepage around the valve cover gasket and oil filter housing, both common leak points on the higher-mileage petrol units. The transmission should shift smoothly without hesitation or shudder, and on diesel variants it is prudent to listen for any auxiliary belt or chain rattle from the engine bay on start-up. A pre-purchase inspection on a ramp would be advisable to examine the underside, paying particular attention to the condition of the exhaust mounting rubbers, any signs of underfloor corrosion, and the general integrity of the subframe mounting areas, none of which have yet been flagged but are areas worth confirming on a 14-year-old chassis approaching the upper end of its expected service life.
