2010 Mercedes-Benz C 2.1L Diesel · LP59 KSE

The vehicle’s most recent MOT test on 2026-01-20—just six months ago—confirms it passed without defects at 124,744 miles, though the record shows two consecutive failures at the January 2024 test (118,583 miles) and a near-miss failure in January 2025 (120,979 miles). The absence of defects in the latest tests suggests the vehicle has been brought up to standard since those earlier issues, but the repeated failures at the same mileage interval (around 118,500–121,000 miles) warrant scrutiny. The pattern implies either a recurring mechanical fault that was temporarily resolved or a test centre’s inconsistent application of standards. The current pass does not guarantee future reliability without further inspection. The mileage progression shows a steady accumulation of approximately 7,800 miles annually, which aligns with typical usage for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, though the 2025–2026 interval (120,994 to 124,744 miles) suggests the vehicle was driven more consistently in the past year. The lack of extended periods of inactivity reduces the risk of neglected fluid degradation or seized components, but the repeated failures at similar mileages indicate a potential underlying issue that may recur. Given the history of failures at the same mileage range, a buyer should prioritise a thorough inspection of the braking system, particularly the rear calipers and pads, as these were likely the cause of the 2024 and 2025 failures. The repeated issues suggest either binding calipers, excessive wear, or a fault in the brake servo or master cylinder. Suspension components—including rear bushes, coil springs, and shock absorbers—should also be checked for wear or corrosion, as these are common failure points in high-mileage Mercedes-Benz models. Structural integrity, especially around the rear subframe and sills, should be examined for signs of rust or damage, as these areas are prone to deterioration in older vehicles. Finally, the exhaust system and emissions controls should be verified, as these are frequently flagged in MOT tests for leaks or malfunction.
