2013 Mercedes-Benz CLS 2.1L Diesel · HF63 YFH

Persistent cosmetic and structural deterioration of the braking system defines the mechanical history of this Mercedes-Benz CLS, which accumulated eight consecutive MOT passes culminating in a successful test on 22 May 2026 at 133,326 miles. While the vehicle has never recorded an official MOT failure across its test history, the recurring nature of advisories highlights a steady accumulation of component wear. Most notably, corrosion on the front brake pipes has been logged repeatedly across multiple consecutive annual tests from 2023 through 2026, often noted alongside grease or protective coatings near the hose connections. Additionally, widespread brake disc wear, pitting, and scoring appeared across multiple axles in 2021 and 2023, while inner tyre edge wear and low tread depths were flagged in 2022 and 2025. With an odometer reading of 133,326 miles accrued over roughly thirteen years, the vehicle has covered an average of approximately 10,256 miles annually, aligning closely with typical UK driving patterns for a large executive diesel saloon. This consistent yearly mileage accumulation avoids the mechanical complications associated with prolonged periods of standing, such as severe battery discharge or heavy underbody oxidation, but it guarantees that major high-stress mechanical assemblies have been subjected to continuous operational friction and load cycles. Prospective buyers must conduct a rigorous physical inspection of the braking components highlighted in the statutory records. During a static inspection, examine the front brake lines near the flexible hose junctions for active flaking or deep oxidation beneath any protective grease layers, and inspect the friction surfaces of all four brake discs for deep scoring or pitting that would necessitate immediate replacement. On the road, pay close attention to the brake pedal feel; any pulsating, sponginess, or delayed hydraulic response during firm deceleration points directly to compromised lines or warped, worn discs that require urgent refurbishment. Beyond the braking system, the ongoing usage profile dictates a thorough check of the vehicle suspension linkages, steering joints, and heavy drivetrain mounts, as high-mileage executive cars frequently develop play in control arm bushes and ball joints. Listen carefully for any metallic knocks, thunks, or suspension groans while driving over uneven road surfaces or speed humps during the test drive, which would indicate degraded rubber bushes or failing dampers. Confirming the condition of these chassis components alongside a comprehensive overhaul of the flagged brake lines will be essential to ensure safe roadworthiness moving forward.
