2018 Mercedes-Benz CLA 1.6L Petrol · LL58 KER

The most recent DVSA examination on 3 December 2025 resulted in a pass with no advisories or defects recorded, and this clean outcome is consistent with the three preceding tests in December 2022, December 2023, and December 2024, which also passed without advisories. The earlier 2021 test carried an advisory for front outer tyres worn close to the legal limit and worn on the edge, and the August 2022 retest contained dangerous failures for both front tyres exhibiting exposed ply or cords together with a nail-in-tyre advisory at the rear. Those failures were rectified at the same visit, and there has been no recurrence of tyre-related or any other defects across the four tests since, indicating that the maintenance trend over the last three years is stable and that the issues noted earlier appear to have been addressed rather than representing an ongoing pattern. With 50,212 miles recorded over eight years, this CLA has averaged roughly 6,276 miles per year, which is broadly typical for its age and suggests regular but moderate use rather than long periods of standing or exceptionally hard running. The mileage gap between the August 2022 test and the December 2022 test is very small, while the more substantial intervals between the later annual tests correspond to average annual mileages well within the expected range for a private owner. There are no significant gaps implying extended lay-up, nor any evidence of rapid accumulation that would disproportionately stress the drivetrain, brakes, or suspension. This pattern is mechanically reassuring, as it tends to keep the engine, turbocharger, transmission, and clutch within their intended wear envelope while still allowing components to reach and maintain operating temperature. Given the clean advisory record across the last four MOTs and the absence of any recurring defect themes, the principal buyer inspection priorities for this vehicle are age- and calendar-related rather than mileage-related. Tyres should be examined closely for sidewall cracking, perishing, and uneven shoulder wear, particularly on the front axle, given the prior advisories for edge wear; even new-looking rubber of similar vintage to the car can harden with age and lose grip in the wet. Brake discs should be inspected for corrosion and the calipers for binding, especially if the vehicle has stood for any extended period, and the brake fluid should be confirmed as recently replaced in line with the manufacturer schedule, as hygroscopic fluid degrades on a time basis regardless of mileage. The 12V battery should be load-tested, as Mercedes-Benz auxiliary batteries and main starter batteries of this age are prone to silent failure, and the coolant, automatic transmission fluid, and engine oil should be verified as within service intervals with documented history. On a test drive, listen for any suspension clonks or knocks over uneven surfaces that might indicate worn drop links, anti-roll bar bushes, or top mounts, all of which are known wear items on the CLA platform given its sporty suspension geometry. Steering should be checked for any vibration, pulling, or uneven self-centring that could point to worn wishbone bushes or tracking misalignment, while the gearbox should shift smoothly without flare or harshness, particularly on the DCT variants where clutch wear and mechatronic issues are a recognised concern. Finally, verify that the vehicle history file includes evidence of regular servicing with genuine parts, that any dashboard warning lights illuminate and extinguish correctly, and that the exhaust, emissions system, and underbody are free from corrosion or fluid leaks, as this will confirm that the clean MOT record reflects genuine mechanical condition rather than simply a pattern of light use masking developing faults.
