2009 Mercedes-Benz C 2.1L Diesel · WOI 514

The vehicle is currently roadworthy, but the maintenance history reveals a reactive rather than proactive approach to repairs. While the most recent test in July 2025 at 162,671 miles passed, it introduced new advisories regarding worn front brake discs and play in both wheel bearings. This follows a period where mechanical faults were only addressed after failing a test. The trend suggests a stable condition in terms of passing inspections, but the underlying components are increasingly reaching the end of their functional service life. At 17 years old, the recorded 162,671 miles represent an average usage of approximately 9,500 miles per year, which is consistent with typical UK mileage for this age. The data shows consistent use, with roughly 8,600 miles covered between June 2024 and July 2025, and another 9,200 miles in the preceding year. This regular interval suggests the car has been driven frequently, which explains the degradation of rubber components and metalwork noted in the record. A buyer must conduct a thorough inspection of the rear subframe, as corrosion was flagged in two consecutive 2023 tests. Although the vehicle passed subsequently, the presence of structural rust on a subframe is a long-term risk that requires monitoring for thinning. The 2024 failure due to excessive corrosion on rear brake pipes indicates that the lines were recently replaced, but the area should be checked for fluid leaks or further degradation elsewhere in the braking hydraulic system. Attention should also be paid to the front end suspension. The 2025 advisory for wheel bearing play indicates that replacement is imminent. The recurring history of perishing tyres, blown bulbs, and failed anti-roll bar linkages suggests that consumable items are often neglected until they cause a failure. A physical check of all suspension bushes, joints, and tyres is essential to ensure no further mechanical wear has developed beyond what the tester identified.
