2016 Mercedes-Benz GLC 2.1L Diesel · XX66 AJS

The 2025‑10‑08 MOT at 85,741 miles passed, yet the immediate prior 2025‑10‑07 failure at 85,733 miles for a fractured offside rear coil spring shows a worsening trend in suspension integrity, while brake disc wear remains unchanged across recent tests. The vehicle therefore cannot be judged fully roadworthy until the suspension defect is rectified. Mileage has risen steadily from 53,482 miles in the 2022 test to 85,741 miles in the 2025 test, an increase of 32,259 miles over three years, or roughly 10,750 miles per year, indicating heavy usage and accelerated wear on consumables. No significant gaps exist in the annual records. A buyer should first examine the rear suspension, paying close attention to the coil spring’s condition, mounting brackets and associated bushes, as the recent fracture points to potential fatigue or impact damage. Check for any previous repairs or replacements of suspension components. Inspection of the brake system is essential: verify the condition of the front and rear discs for pitting or scoring, assess caliper binding, and confirm pad thickness, while also reviewing tyre wear patterns for edge wear that may indicate alignment or suspension issues, and investigate the slight rear oil leak for source and severity.
