2013 Mercedes-Benz CLA 1.6L Petrol · CS12 RUS

The most recent MOT test on 2026-01-27 resulted in a passing outcome, but the preceding test on the same date in 2025-01-27 revealed a pattern of recurring issues that warrant careful consideration. The vehicle’s MOT history is marked by two failures in the past two years, both of which were classified as major defects, specifically a fractured offside rear coil spring and incorrect colouration of the offside rear direction indicators. These failures suggest a potential underlying issue with structural integrity in the rear suspension system, which could indicate wear progression in the coil spring or related suspension components. The nearside rear tyre advisory from 2025-02-10, while not a failure, highlights a critical wear concern that should not be overlooked, as worn tyres on the edge can compromise traction and increase the risk of hydroplaning or uneven handling. The fact that these issues resurfaced in 2024-01-25 underscores the need for a thorough inspection of the suspension and tyre condition, as repeated failures often point to a systemic problem rather than isolated incidents. The vehicle’s recorded mileage of 135,060 miles at the time of this assessment represents a moderate annual usage rate of approximately 10,389 miles per year, which is within the expected range for a 13-year-old Mercedes-Benz CLA given typical UK driving conditions. However, the mileage data alone does not fully capture the vehicle’s operational profile, as the lack of recent mileage increments could imply prolonged periods of inactivity, which may exacerbate issues such as standing corrosion, fluid degradation, or component stiffness. For example, standing for extended periods can lead to brake disc corrosion, binding calipers, or suspension bush wear, as lubricants break down and components seize. Conversely, if the vehicle has accumulated higher mileage more recently, the wear on consumables like brake pads, suspension bushings, and tyres would be more pronounced, necessitating a closer inspection of these areas. Given the recent MOT failures and advisories, the prospective buyer should prioritise a comprehensive mechanical inspection of the rear suspension system, focusing particularly on the coil springs, shock absorbers, and associated mounting points. During a test drive, listen for unusual noises such as clunks or rattles from the rear, which may indicate loose suspension components or worn bushes. Inspect the rear suspension for signs of excessive play or binding, and check for uneven tyre wear patterns, which could suggest misalignment or suspension misalignment. The fractured coil spring failure suggests that the spring may have failed catastrophically, and further investigation into the remaining suspension components is essential to prevent recurrence. Additionally, verify that the rear direction indicators are functioning correctly and that their colour coding is compliant with current regulations, as incorrect colouration can pose a safety hazard. Beyond the suspension, the buyer should conduct a thorough examination of the vehicle’s tyres, focusing on the nearside rear tyre for signs of excessive wear or damage, as the 2025 advisory indicates the tyre is worn close to the legal limit. Check for uneven tread wear, which may signal alignment or suspension issues, and inspect the tyre walls for signs of cracking or perishing, particularly if the vehicle has been stationary for extended periods. The brake system should also be inspected, with particular attention to the rear discs for signs of corrosion or binding, which can occur when the vehicle stands in damp conditions. Ensure that the brake fluid is at the correct level and free from contamination, as standing brake fluid can degrade over time, leading to reduced braking performance. Finally, given the vehicle’s age and the potential for prolonged inactivity, a check of the 12-volt battery health and the condition of the electrical system is advisable, as standing vehicles can suffer from battery discharge or corrosion in terminals. If possible, obtain a service history to confirm that routine maintenance such as oil changes, fluid top-ups, and timing belt replacement (if applicable) have been conducted according to manufacturer specifications.
