2012 Mercedes-Benz C 2.1L Diesel · ML62 DWM

The most recent DVSA MOT, carried out on 7 April 2023, was passed with no recorded defects, indicating that the vehicle currently meets the statutory safety and emissions standards. Over the six‑year record the pattern moves from a failure in early 2020 – principally for non‑functioning front lighting units – to a series of clean passes in 2021, 2022 and 2023, with only advisory items noted in 2018 and early 2020 concerning rear brake wear and parking‑brake effort. This progression suggests that any earlier electrical faults have been remedied and that the overall maintenance trajectory is now stable and improving. At 105 003 miles on a 2012 model the average annual mileage works out at roughly 7 500 miles per year, which sits comfortably within the normal UK usage envelope for a fourteen‑year‑old saloon. There are no obvious large mileage gaps in the MOT record, so the car does not appear to have endured prolonged periods of inactivity that could promote component corrosion, nor does it show the high‑kilometre wear patterns associated with intensive use. The moderate mileage implies that consumables such as brake pads, discs, tyres and suspension components will have experienced typical wear but should not be excessively depleted. Prospective buyers should give particular attention to the rear braking system, as advisories in 2018 and early 2020 highlighted disc wear and thin pads. Inspect the rear discs for surface scoring, pitting or excessive rust and verify that the pads have a remaining thickness of at least 2 mm; any pulsation or shudder when applying the rear brake, or a higher pedal effort, may indicate that the pads are nearing the end of their service life. The parking‑brake effort advisory also warrants a functional check – the hand‑brake should hold the vehicle securely on an incline without requiring excessive lever travel, and the rear calipers should release fully without dragging, which would be audible as a faint grinding or felt as a pull to one side during a slow‑speed stop. Given the vehicle’s age, a thorough visual and tactile inspection of age‑related items is essential. Tyre sidewalls should be examined for cracking, dry‑rot or age‑related hardening, especially if the tyres are over ten years old regardless of tread depth. The 12‑volt battery, likely approaching the end of its typical three‑ to five‑year service life, should be load‑tested for cranking performance and checked for any signs of electrolyte leakage. Examine all lighting units – indicators, headlamps and position lamps – to confirm they illuminate correctly and that the lenses are free of moisture or condensation. Finally, verify that the engine oil, coolant, brake fluid and power‑steering fluid have been changed at calendar intervals; fluid should be clear, free of particulates and at the correct level, as time‑based degradation can lead to seal wear and reduced component reliability even on a vehicle with modest mileage.
