2005 Mercedes-Benz CLK 3.2L Petrol · HT05 HNJ

The most recent MOT test on the 2005 Mercedes-Benz CLK, conducted on 2026-05-11, resulted in a passing outcome, though it did reveal several persistent issues that warrant careful consideration. While the vehicle has not failed an MOT since 2019, the recurring advisories and minor defects suggest a pattern of wear and potential underlying mechanical concerns rather than a stable maintenance record. The near-side front anti-roll bar linkage ball joint dust cover deterioration from 2022 and 2026, alongside the oil leak advisories in 2020 and 2026, indicate that the suspension components are experiencing accelerated degradation. The brake pipe corrosion and grease buildup noted in 2026 further highlight a systemic issue with fluid integrity and potential contamination, which could compromise braking performance over time. These findings do not immediately render the vehicle unsafe but underscore the need for proactive attention to prevent further deterioration. Without explicit mileage data, it is impossible to accurately assess annual usage rates or whether the vehicle has accumulated excessive wear from high mileage or prolonged periods of inactivity. However, the fact that the CLK was last tested in 2026—nearly seven years after its 2009 production year—suggests either infrequent use or a period of extended storage, both of which can accelerate wear on components like suspension bushes, seals, and brake systems. The presence of minor defects such as tyre wear close to legal limits in 2019 and 2026, combined with the lack of recent mileage updates, implies that the vehicle may have been driven sparingly or stored without regular maintenance. This could lead to issues such as standing corrosion in brake components, tyre sidewall perishing from age, or fluid degradation in systems like the cooling or hydraulic circuits, which are more pronounced when a vehicle is not in regular use. To proceed with a thorough inspection, the prospective buyer should begin by examining the suspension components for signs of further deterioration. The near-side front anti-roll bar linkage ball joint and track rod end ball joint play noted in 2019 and 2020, respectively, indicate that these joints may be worn beyond their serviceable limits. During a test drive, listen for unusual clunking or rattling noises from the front suspension, particularly when the vehicle is driven over bumps or at low speeds. The clunks could originate from worn suspension bushes or a failing ball joint, which may eventually lead to misalignment, handling instability, or even a complete failure if left unaddressed. Additionally, check for uneven tyre wear patterns, which could suggest misalignment caused by worn suspension components or steering system issues. If the clunks are present, the buyer should also verify that the vehicle’s steering is straight and responsive, as a failing ball joint can lead to binding or excessive play in the steering wheel. Beyond the suspension, the brake system requires immediate attention due to the recurring advisories and potential corrosion risks. The brake pipe corrosion and grease buildup in 2026 are particularly concerning, as they may indicate fluid contamination or moisture ingress, which can compromise braking efficiency and safety. During a test drive, observe for signs of brake shudder, pulsation, or reduced stopping power, which could be indicative of contaminated brake fluid or warped discs. Inspect the brake discs and pads for signs of excessive wear, corrosion, or glazing, and listen for any grinding noises when applying the brakes—these can signal that the pads are nearing the limit or that the discs are damaged. The thin brake pads noted in previous MOTs suggest that a full brake service, including pad replacement and disc inspection, is overdue. The buyer should also check for any standing corrosion on the brake calipers or backing plates, as prolonged exposure to moisture can lead to binding or reduced braking effectiveness. If the vehicle has been stored for extended periods, it is advisable to flush and replace the brake fluid to remove any contaminants and restore optimal performance. Finally, the offside and near-side mirrors, though not critical to roadworthiness, should be inspected for further deterioration, as the damaged mirrors from previous MOTs may have been overlooked or ignored, potentially posing a safety hazard if not replaced. The buyer should also verify that all lights are functional and that the mirrors are correctly aligned to ensure visibility.
