2018 Mercedes-Benz CLA 1.6L Petrol · YN68 WVC

The 2018 Mercedes-Benz CLA presented a Pass on its most recent DVSA examination dated 6 December 2025, albeit accompanied by several advisories that warrant careful attention from any prospective buyer. While the test outcome itself is favourable, the emergence of four advisories after three entirely clean tests in 2023 and 2024 suggests a mild downward shift in condition, likely reflecting the natural wear progression of an eight-year-old vehicle rather than any specific mechanical neglect. The presence of tyre-related advisories on both inner and outer locations indicates that the wheels and suspension geometry should be evaluated thoroughly, as uneven or premature tyre wear can be symptomatic of deeper issues such as worn bushes, weak shock absorbers, or tracking misalignment. With 77,566 miles recorded over approximately eight years, this CLA has covered around 9,696 miles annually. This figure is broadly typical for a vehicle of its age and class and suggests consistent, regular use rather than prolonged periods of standing or conversely excessive motorway mileage. Such a usage pattern is generally positive for mechanical health, as regular running helps prevent the corrosion and fluid degradation that often plague low-mileage or stored vehicles. There are no notable gaps in the MOT record, with tests conducted annually since 2021, which suggests the vehicle has been maintained within the standard roadworthiness framework throughout its life. The most significant concern arising from the MOT history relates to tyre wear and condition. The advisory on the offside front tyre noted slight damage and perishing alongside wear close to the legal limit, which raises questions about replacement timing and potentially the alignment geometry. On a test drive, listen for humming or drone from tyres that may indicate uneven wear patterns, and inspect the offside front wheel closely for any uneven shoulder wear that could point to camber issues or worn suspension components. Additionally, the nearside rear tyre failure in November 2021 due to a deep cut reaching the ply or cords, together with inner-edge wear, is worth investigating. Inner-edge wear on a rear tyre can sometimes indicate rear axle geometry issues or, on certain Mercedes platforms, worn trailing arm bushes. The buyer should jack the vehicle safely and inspect the rear suspension bushes for cracking, perishing, or play, and check that the rear tracking geometry falls within tolerance during a four-wheel laser alignment check. Several age- and mileage-appropriate inspections are strongly advised beyond what the MOT record directly reveals. At eight years old, the offside front tyre perishing already noted could indicate that the vehicle has been stored or used in conditions conducive to sidewall cracking, so all four tyres should be closely examined for ozone damage, particularly in the sidewall flex zones. The brake discs and calipers should be checked for corrosion or seizing after periods of standing, as Mercedes sliding calipers are known to bind, leading to uneven pad wear and elevated drag. Brake fluid should be renewed every two years regardless of mileage, and it is worth requesting evidence that this has been carried out, along with confirmation of recent engine coolant and automatic gearbox oil replacement if this latter is documented. Finally, verify the condition of the 12V battery, as Mercedes-Benz vehicles of this generation utilise a battery management system that requires registration of new units, and an ageing battery can trigger warning messages and electrical gremlins. The discoloured offside rear direction indicator noted on the latest test is a minor cosmetic item easily rectified, but it is worth ensuring that all exterior bulbs illuminate correctly and that the rear light clusters are free from moisture ingress, which is a known concern on CLA models of this era.
