2004 Mercedes-Benz CLK 2.6L Petrol · ST54 LGE

The most recent MOT test on 2026-05-22 resulted in a passing outcome, though it revealed persistent and concerning advisories that suggest a pattern of wear and potential underlying issues requiring attention. While this test did not fail, the recurring nature of the steering rack inner joint play, front tyre edge wear, and rear sub-frame corrosion—alongside the previous failures in 2024 and 2023—indicates that the vehicle has not been adequately maintained to prevent progressive mechanical degradation. The supplementary restraint system (SRS) fault remains unresolved from multiple tests, and the anti-lock braking system (ABS) fault from 2026-04-07 highlights a critical electronic component that must be addressed before the vehicle achieves full roadworthiness. The front brake discs being worn and pitted further underscore the need for proactive servicing, as these conditions can lead to reduced braking efficiency and premature disc replacement if not managed. The recorded mileage of 82,264 miles over approximately 22 years equates to roughly 3,739 miles annually, which is unusually low for a vehicle of this age and model, particularly one that has undergone multiple MOT failures. Such low mileage often reflects periods of prolonged inactivity or infrequent use, which can exacerbate issues related to standing corrosion, fluid degradation, and component dryness. For instance, the rear sub-frame corrosion advisories and brake pipe corrosion suggest that the vehicle has been stationary for extended periods, allowing moisture to penetrate and accelerate rust formation. Additionally, the rear tyres being worn to the inner edges and below legal tread depth in some instances may indicate uneven loading or poor suspension alignment, which could have been exacerbated by infrequent driving. The rapid deterioration of certain components—such as the front coil spring fracturing in 2023—also suggests that the vehicle may have been subjected to stress cycles from standing or minor impacts, further compromising structural integrity. To proceed with a purchase, the prospective buyer should conduct a meticulous inspection focusing on the steering and suspension system, as the inner joint play and anti-roll bar linkage wear are critical areas of concern. During a test drive, listen for excessive clunking or rattling in the steering wheel or wheel arches, which may indicate further deterioration in the suspension bushes or ball joints. Inspect the steering rack for any signs of oil leaks or excessive movement when turning, and check for uneven tyre wear patterns, which could signal misalignment or suspension issues. The brake system should be thoroughly examined, including the condition of the discs, pads, and hoses, as the previous MOTs noted significant wear and corrosion. Pay particular attention to the rear brake pipes for leaks or excessive corrosion, as these can compromise hydraulic braking efficiency and lead to dangerous failure. Additionally, verify that the SRS and ABS systems are functioning correctly by ensuring no warning lights illuminate during the test drive. Beyond the mechanical checks, the buyer should address the fluid and structural health of the vehicle. Given the low annual mileage, the engine oil, transmission fluid, and coolant should be replaced according to the manufacturer’s recommended service intervals, as standing fluids can degrade over time and lead to premature component failure. Inspect the tyres for sidewall cracking or perishing, which can occur even with low mileage due to age-related deterioration. Check the battery terminals for corrosion and ensure the 12V system is functioning properly, as a weak battery can exacerbate electrical faults like the SRS and ABS warnings. Finally, verify that the service history records are complete, particularly for the suspension and braking systems, to confirm whether any prior repairs were documented. If the vehicle has been stationary for long periods, consider having the exhaust system, fuel lines, and electrical connections inspected for signs of corrosion or damage, as these areas are particularly vulnerable to deterioration when unused.
