2017 Mercedes-Benz CLA 1.6L Petrol · KP67 DLD

The 2017 Mercedes-Benz CLA passed its most recent DVSA MOT test on 1 November 2025, though the examiner recorded an advisory regarding a rear brake disc that is worn, pitted, or scored but not considered seriously weakened at this stage. Looking at the broader test history, the maintenance trend shows some deterioration over time. The 2023 and 2021 tests were passed with no advisories, indicating a sound mechanical state, but the 2024 examination surfaced four tyre advisories across both axles, all noting edge or inner edge wear, alongside a rear brake pad advisory for thin pads. This progression, combined with the latest brake disc advisory, suggests that braking and undercarriage components are now entering a phase of more active wear. The recurrence of tyre wear patterns across all four corners in a single test is particularly telling and warrants close inspection, as it often points to an underlying suspension geometry or alignment issue rather than simply ageing rubber. Recorded mileage stands at 112,939 miles over approximately nine years, which equates to roughly 12,500 miles annually. This is a notably high annual figure for a premium coupe of this class and exceeds typical UK average usage by a considerable margin. Such sustained high-mileage operation accelerates wear on mechanical consumables including brake components, suspension bushes, coil springs, and drivetrain mounts. There is a substantial gap in the MOT record between the May 2020 test and the July 2021 test, but mileage progression appears broadly consistent otherwise. The combination of high annual mileage and recent brake-related advisories suggests that this vehicle has been used as a regular long-distance or commuter car, which generally means the engine and gearbox have benefited from regular warm operation but the chassis, braking, and suspension components have absorbed considerable accumulated wear. Given the rear brake disc advisory from late 2025, a prospective buyer should prioritise a thorough inspection of the rear braking system. On a test drive, listen for any brake shudder or vibration through the steering wheel or pedal under firm deceleration, which would indicate the pitted rear disc has progressed to the point of requiring replacement. Check for any pulling to one side under braking, which can suggest a binding caliper or uneven pad wear, and inspect the rear pads for remaining material thickness. The 2024 advisories regarding inner edge wear on all four tyres strongly suggest a four-wheel alignment or tracking issue, so it would be prudent to verify that this has been rectified and to inspect the front suspension components, including wishbone bushes, drop links, and top mounts, for any clunks or knocking over uneven road surfaces. Uneven tyre wear, if recurring, can also place additional strain on the steering rack and track rod ends over time. Beyond the recorded advisories, a vehicle of this age and high mileage warrants a comprehensive mechanical inspection. Examine the exhaust system, including the mountings and catalytic converter, for corrosion or heat damage, as the undertray fitted as noted in 2020 may be concealing or protecting certain components. Inspect the condition of all visible suspension bushes for perishing or cracking, particularly the rear axle bushes which carry significant load. Check for any signs of fluid leaks from the engine, transmission, or differential, and verify that the cambelt or timing chain service interval has been observed according to manufacturer schedule, as the latter is particularly critical on this generation of Mercedes engines. Given the high mileage, a compression or leak-down test on the engine would be a wise precaution. Finally, confirm the 12-volt battery health, as Mercedes-Benz vehicles of this era are sensitive to voltage irregularities, and ensure that all time-based services such as brake fluid replacement, coolant renewal, and automatic transmission fluid and filter changes have been completed at the correct intervals regardless of recorded mileage, since fluid degradation occurs with calendar age as well as use.
