2010 Mercedes-Benz C 1.8L Petrol · KS10 VOG

A recurring theme across the MOT record is the vehicle’s brake system and oil containment – multiple failures and advisories point to chronic wear and corrosion. In 2024 a dangerous front‑pad thickness of under 1.5 mm and severely worn front discs triggered a fail, while the same year an off‑side rear tyre was deemed dangerous and a near‑side rear brake pipe was flagged as likely to detach. The 2025 tests show the oil leak escalating from a non‑excessive advisory to a major, excessive leak, and the parking‑brake efficiency fell below the required standard, resulting in another fail. Although the most recent test in October 2025 was passed, an advisory still notes the near‑side rear brake slack adjuster needs adjustment, underscoring that brake‑related issues remain a persistent concern. At 150,255 mi the car averages roughly 9,400 mi per year, a mileage rate that sits squarely within normal use for a sixteen‑year‑old saloon. The MOT history is continuous with annual tests, showing no prolonged periods of inactivity that might mask hidden deterioration. Nonetheless, the cumulative mileage combined with the documented brake wear, tyre thinning and sub‑frame corrosion suggests that consumables and load‑bearing components have been subjected to a typical wear cycle and may be approaching the end of their service lives. When inspecting the brakes, verify the external condition of the front pads and discs – they should exceed the legal minimum thickness and feel solid under finger pressure. Test the parking‑brake lever for a firm, consistent hold and listen for any hissing that could indicate a leaking pipe. Examine the rear brake slack adjuster for free play and ensure the rear brake pipe is free of corrosion, rust or grease buildup that could compromise its attachment. During a road test, note any pedal pulsation, sponginess or a pull to one side, which would corroborate the earlier pipe and sub‑frame concerns. For the oil leak, look for fresh oil stains around the valve cover, oil filter housing and under the engine, and confirm that the oil level is stable after a short drive. A thorough pre‑purchase examination should concentrate on the brake hydraulics, parking‑brake mechanism, rear brake pipe mounting points and the condition of the anti‑roll bar dust covers that have shown severe deterioration on both sides. The near‑side rear sub‑frame, previously recorded as damaged but not severely weakened, warrants a visual inspection for rust penetration or flex under load. Tyre tread depth, especially on the off‑side rear where it was once below legal limits, must be measured and sidewalls checked for cracking. Finally, confirm full operation of both headlamps and inspect the windscreen for the noted chip, as any structural compromise could affect safety. Addressing these items before purchase will clarify whether the vehicle can meet future MOT standards without immediate remedial work.
