2006 Mercedes-Benz CLK 2.1L Diesel · GD06 AAN

The vehicle is currently roadworthy but the maintenance trend shows a clear progression of suspension and braking system degradation. While the most recent test in January 2026 at 160,076 miles passed, the tester identified new issues including steering rack inner joint play and worn anti-roll bar linkages. These faults represent a worsening of the suspension wear issues previously noted in 2023 and 2025, suggesting that the front-end components are now reaching the end of their functional life and require proactive replacement to maintain safety. The mileage of 160,076 miles over twenty years reflects an average usage of approximately 8,000 miles per annum, which is consistent with a grand tourer of this age. The data shows a steady rate of use with roughly 7,000 to 8,000 miles added each year between 2019 and 2026. This consistent mileage suggests the vehicle has not sat stationary for long periods, though the age of the rubber components and metal lines indicates that the age of the car, rather than the mileage, is the primary driver of the current mechanical failures. A buyer must pay close attention to the brake lines and suspension geometry. The record shows a persistent history of corrosion on the nearside rear brake pipe dating back to 2022, which escalated to a failure in 2024 due to excessive corrosion on multiple front lines. Although the car passed most recently, the presence of pitted and scored discs in early 2026 indicates the braking system is under significant stress. The recurring failures of ball joints and anti-roll bar links across multiple years suggest that the entire suspension assembly is deteriorating. Physical inspection of the steering rack is essential given the offside inner joint play recently recorded in the January 2026 test, as this can be a costly repair if it is not addressed. Additionally, the power steering seepage noted in 2022 should be re-checked to ensure the leak has not worsened or affected the surrounding rubberwork. The buyer should also verify that the corroded brake pipes have been properly replaced rather than merely cleaned or treated, as the history shows a pattern of allowing corrosion to persist until it reaches a failure threshold.
