2018 Mercedes-Benz CLA 1.6L Petrol · NS68 MAR

The most recent MOT test for the 2018 Mercedes-Benz CLA on 2026-07-14 was passed with no recorded defects, marking a positive outcome following the vehicle’s previous failure in August 2024. Despite the single major failure in 2024—an incorrect near-side rear direction indicator colour—subsequent MOTs have been clean, indicating a stable maintenance trend. The absence of repeated failures or advisories suggests that the electrical system for the indicators has been rectified, though the buyer should verify the correction was permanent by inspecting the wiring harness and indicator bulb assembly for any residual faults or wear. The lack of further issues over the past two years points to either effective remedial work or a rare occurrence of the original problem, making this a relatively reassuring development. The recorded mileage of 44,079 miles for a vehicle aged eight years is exceptionally low, averaging just 5,510 miles per year—a rate that typically reflects either minimal use, long periods of stationary storage, or a combination of both. Such low mileage can lead to several potential concerns, particularly in components that degrade over time rather than through wear from driving. For instance, standing for extended periods can cause corrosion to develop in the brake system, especially on the near-side rear caliper and disc, where moisture and road salt can accelerate rust formation. Additionally, the tyres, though not yet at legal limits, may exhibit signs of ageing, such as sidewall cracking or perishing, which can compromise structural integrity and handling performance. The advisories from the 2022 MOT regarding tyre wear close to legal limits—particularly the edge wear—also warrant attention, as this pattern often indicates misalignment or suspension issues that could worsen over time if unaddressed. Given the vehicle’s low mileage and clean MOT history aside from the indicator fault, the buyer should conduct a thorough physical inspection to address both immediate and long-term concerns. Start by examining the tyres for any signs of ageing, such as cracks or dry rot in the sidewalls, and check the tread depth for uniformity and wear patterns. The brake system should be inspected for signs of corrosion on the discs, particularly on the near-side rear where the 2024 failure occurred, and listen for any grinding or squeaking noises during braking, which could indicate worn brake pads or binding calipers. The electrical system, especially the indicators, should be tested thoroughly by turning them on and off repeatedly to ensure no further issues arise, and check the wiring for any signs of damage or corrosion. Additionally, since the vehicle has not been driven extensively, the battery should be tested for strength, as prolonged disuse can lead to reduced charge capacity or sulphation. Finally, the fluid levels—particularly the engine oil, brake fluid, and coolant—should be checked, with a note taken of their condition and colour, as fluids degrade over time even without use. If the vehicle has been stored in a damp or salty environment, consider a thorough inspection of the undercarriage for rust or corrosion, particularly around the suspension mounts and exhaust system, which are common areas for premature failure in low-mileage vehicles.
