2015 Mercedes-Benz CLA 2.1L Diesel · DF65 EWA

A consistent pattern of brake-related wear emerges from the MOT history of this 2015 Mercedes-Benz CLA, with the most recent test on 27 July 2024 passing subject only to an advisory for rear brake pads wearing thin. Across the eight recorded tests, the front braking system has been flagged on three separate occasions: a dangerous front brake pad failure in December 2019, worn-to-indicator front pads in May 2023 accompanied by a disc wear advisory, and the rear pads now thinning in mid-2024. This is not the profile of a vehicle that has passed MOTs without mechanical comment; rather, it suggests the friction materials and possibly the discs have been worked hard and may continue to demand attention. The May 2023 test also recorded a non-functioning nearside front dipped beam, which although resolved for the subsequent pass demonstrates that electrical items such as headlamp bulbs and the associated wiring or ballast components on this model merit a deliberate check. With 83,079 miles spread over eleven years, the CLA has averaged roughly 7,550 miles per year, which is broadly typical for a car of this age and avoids the extremes of very low annual use or high-mileage motorway accumulation. There is, however, a notable testing gap between January 2022 and July 2024, with no MOT recorded for the intervening period, indicating the vehicle was either off the road, exempt from testing, or simply untested for over two years despite remaining in service. A test conducted after such an interval will only reflect the condition on the day, so mechanical deterioration in items such as tyres, brakes, suspension bushes and exhaust mounting rubber could have progressed without observation. Buyers should treat the most recent pass as a snapshot and not as evidence of continuous roadworthiness across that gap. Front brake components are the single most repeatedly flagged area, so a close inspection of the pads, discs and calipers is essential. On a test drive, listen for any scraping or grinding from the front wheels under light braking, feel for vibration or judder through the steering wheel when stopping from higher speeds, and watch for the car pulling to one side, which can indicate a binding caliper or uneven pad wear. Inspect the front discs through the wheel for a pronounced lip on the outer edge and for any blueing or scoring on the friction surface, as these confirm the disc has run beyond its service life. The rear pads were noted as wearing thin in 2024, so confirm whether they have since been replaced and check the rear discs for similar wear patterns. The headlamp issue from 2023 also warrants a functional check, including both dipped and main beam operation on both sides, as well as the operation of any xenon or LED modules which can fail intermittently before failing completely. Given the age and mileage, the suspension should be examined for knocking over uneven road surfaces, particularly from the front lower arms, anti-roll bar bushes and top mount bearings, all common wear points on the CLA platform. Steering play should be assessed with the engine running and the wheel turned lock to lock, and any clonking from the column area noted. Finally, a thorough underside inspection on a ramp is strongly recommended to look for any corrosion on subframe and suspension components, oil leaks from the engine and transmission, and the condition of the exhaust mounting rubbers, none of which are captured in the MOT record but all of which become increasingly relevant on an eleven-year-old vehicle.
