2011 Mercedes-Benz C 1.8L Petrol · EK11 AAV

Persistent brake pipe corrosion and a pattern of recurring minor defects define the mechanical state of this vehicle. While it achieved a pass on 14 November 2025, the record shows a trend of lingering issues, including frayed seat belt webbing and corroded rear brake lines that have appeared across multiple tests. The addition of a coolant leak in the latest inspection suggests a shift toward more urgent fluid system maintenance. The recorded mileage of 136,407 miles is typical for a fifteen-year-old vehicle, averaging roughly 9,094 miles annually. This steady accumulation indicates the car has been used regularly, avoiding the risks associated with long-term standing. However, this level of wear naturally impacts the longevity of rubber components and suspension linkages, which aligns with the previously recorded play in the front lower suspension arm ball joints. A thorough inspection of the braking system is critical, particularly the rear brake pipes which have been flagged as corroded and covered in grease since November 2024. On a test drive, be alert for any pedal judder or a soft feel under heavy braking, which may indicate the extent of the disc wear and pipe degradation. The historical mention of play in the offside front lower suspension arm ball joint means you should listen for knocks or clunks when traversing speed bumps or during low-speed manoeuvring. The coolant leak identified in the November 2025 test is a priority; check the coolant expansion tank level and look for crusting or leaks around the radiator and hoses. The nearside front seat belt webbing has been noted as frayed for two consecutive years and represents a safety defect that needs rectification. Furthermore, with both nearside tyres currently flagged as worn close to the legal limit, immediate replacement is necessary to maintain roadworthiness.
