2012 Mercedes-Benz C 2.1L Diesel · FT12 PDY

A history of severe structural corrosion and component fractures defines the roadworthiness record of this fourteen-year-old Mercedes-Benz C-Class. The vehicle successfully passed an MOT test on 2026-02-06, but this recent pass follows a volatile period marked by multiple failures, including dangerous structural corrosion around the rear subframe mountings in late 2024, fractured front coil springs and excessively corroded brake pipes in late 2025, and an unsafe rear subframe modification flagged during the same test cycle. Although the most recent inspection resulted in a pass, it carried lingering advisories for grease-covered, corroded brake pipes on the offside front and rear, alongside an offside front tyre worn close to the legal limit. With 128,612 recorded miles accumulated over its fourteen-year lifespan, the vehicle averages roughly 9,187 miles annually, representing a typical usage profile for its age and class. The testing chronology shows consistent yearly submission without extended off-road gaps, meaning wear has been distributed across standard operating intervals rather than compressed into sudden high-mileage bursts. This mileage level places high demands on structural mountings, suspension assemblies, and hydraulic lines, which is directly corroborated by the heavy concentration of corrosion and mechanical failures appearing across the 2023 through 2026 test cycles. Prospective buyers must conduct a rigorous physical inspection underneath the vehicle, prioritizing the structural integrity of the rear subframe mountings that previously triggered dangerous failure notices in late 2024. Closely examine the condition of the brake pipes noted as corroded or grease-covered in the latest test, checking for deep pitting, fluid seepage, or spongy pedal feel during a stationary brake pressure test. Furthermore, listen carefully for metallic clunks, knocks, or uneven damping over potholes and speed bumps during a test drive to verify the condition of the front coil springs and suspension geometry, ensuring no residual defects remain from the extensive repairs required to clear its prior major failure notices. Additional scrutiny should be applied to the remaining consumables and mounting points before finalizing a purchase. Verify that the offside front tyre is replaced promptly to address the legal wear limit advisory, and inspect all wheel arches and floor pans for underlying rust propagation that often accompanies subframe corrosion on this chassis platform. Ensure that any subframe modifications noted in previous records have been fully corrected to manufacturer standards, and check that all braking components respond crisply without binding, vibration, or pulling to one side when decelerating from higher road speeds.
