2011 Mercedes-Benz C 2.1L Diesel · NAZ 300

Brake wear has been the most recurrent theme in this car’s MOT record, with front‑disc condition flagged in 2020, front‑pad thickness noted in 2022 and front‑disc surface advisories re‑appearing in 2024. The 2025 test, however, returned a clean pass with no defects recorded, indicating that the previously highlighted brake issues were likely addressed before that date. Apart from the brake‑related advisories, the only other significant failures were a set of headlamp faults in late‑2022 and a windscreen defect in 2020, both of which were rectified for the subsequent passes. At 89,781 mi over fifteen years the vehicle averages just under 6,000 mi per annum, a mileage figure that is low for a 2011 model. The MOT history shows annual testing with no prolonged gaps, suggesting the car has been driven consistently rather than sitting idle for extended periods. Low annual mileage generally reduces cumulative wear on drivetrain and suspension components, yet the recurring brake advisories imply that even modest use has been sufficient to generate measurable wear on the braking system, possibly accelerated by driving style or the vehicle’s weight. When inspecting the brakes, feel for any pulsation or sponginess in the pedal and listen for squeal or grinding under moderate braking – both could indicate that the discs or pads are nearing the end of their service life despite the recent pass. Examine the disc surfaces for scoring or uneven wear, and verify that the pads are of even thickness across both wheels. Confirm that the headlamps illuminate fully on both dipped and main beams and that the aim is centred; a mis‑aimed lamp can cause glare and may be a symptom of mounting issues. Also check the windscreen for any cracks or chips that could have propagated since the 2020 advisory. Finally, inspect the rear tyres for edge wear that was previously close to the legal limit, and assess the rear coil springs for any signs of corrosion or fatigue, especially around mounting points, as the 2020 advisory highlighted possible rust. During a low‑speed drive, note any clunking or uneven bounce over bumps, which could betray deteriorated spring or bushings. A thorough visual check of the front disc faces for corrosion and the condition of the brake caliper pins will help confirm that the earlier disc advisories have been fully resolved before committing to purchase.
