2005 Mercedes-Benz C 1.8L Petrol · KP05 VLF

The vehicle is currently unroadworthy and shows a worsening trend in mechanical and structural health. The most recent test on 27 May 2026 at 145,868 miles resulted in multiple critical failures involving the emissions system. The tester recorded excessive carbon monoxide, hydrocarbons, and lambda readings, alongside an inoperative engine management warning light. This indicates a significant engine management issue or sensor failure that remains unaddressed. Furthermore, the offside front lower suspension arm ball joint and deteriorated brake hoses represent a failure in preventative maintenance. At 145,868 miles, this 21-year-old Mercedes has averaged approximately 6,900 miles per year, which is consistent with typical usage for a vehicle of its age. The mileage pattern is steady, with roughly 6,500 miles covered between June 2024 and May 2025, and another 6,500 miles leading into May 2026. While the mileage accumulation is linear, the frequency of failures suggests that the vehicle is entering a period of high despite despite relatively low annual distance driven. A buyer must conduct a thorough inspection of the braking and suspension systems. Corroded rear brake pipes have been a recurring advisory since at least June 2024, indicating persistent deep-seated rust that has not been treated or replaced. The repeated failure of ball joints and the deterioration of brake hoses suggest the rubber and metal components require comprehensive replacement. The emissions failures in the 2026 test are particularly concerning, requiring a diagnostic check to determine if the oxygen sensors, catalytic converter, or fuel system are failing, especially as the engine management light is flagged as inoperative.
