2010 Mercedes-Benz CLS 3.0L Diesel · M123 CSG

The most recent MOT on 2026-03-02 recorded a pass , but the same vehicle failed just 8 days earlier on 2026-02-24. Both tests listed nearly identical defects, including corroded brake pipes, wheel bearing play, and tyre wear. This suggests unresolved issues or recurring faults that may indicate ongoing mechanical degradation. The 2026-03-02 test noted an oil leak, corroded brake pipes, and wheel bearings with slight play, all of which were previously recorded in earlier MOTs. A recurring pattern of brake pipe corrosion (noted in 2024–2026) and wheel bearing play (2024–2026) highlights potential exposure to moisture, road salt, or inadequate maintenance. Corrosion on the nearside rear coil spring (2026-03-02) and suspension components (2026-02-24) further points to environmental stress or lack of protective measures. Tyre wear near legal limits (2025–2026) suggests uneven tread or alignment issues, which could worsen over time. The trend shows no improvement in critical areas. Defects like brake pipe corrosion and wheel bearing play reappeared in consecutive tests, indicating persistent risks. While mileage (100,889 miles over 16 years) is typical for the vehicle’s age, the frequency of corrosion-related issues implies possible exposure to harsh conditions or insufficient maintenance.
