2018 Mercedes-Benz CLA 1.6L Petrol · CB09 CCC

The vehicle achieved a PASS at its most recent DVSA roadworthiness examination on 13 March 2026, although two advisories were issued against the braking system. Specifically, both the nearside and offside front brake discs were noted as worn, pitted, or scored, though not seriously weakened at the time of test. The preceding four annual examinations (2022, 2023, 2024, and 2025) returned clean passes with no advisories or defects recorded, indicating a generally stable maintenance trend over the longer term. However, the emergence of brake disc wear at the front axle after several consecutive clean tests suggests that attention to the braking system is now warranted, and this should form a central part of any pre-purchase inspection. With 37,363 miles recorded over approximately eight years, this CLA has averaged around 4,670 miles annually, which is notably low for its age and indicative of either predominantly short-trip use or extended periods of standing between journeys. Such low annual mileage has mechanical implications: brake discs, callipers, and rear drums are more susceptible to corrosion and seizing through lack of regular use, while the engine, fuel system, and exhaust may suffer from infrequent oil circulation and moisture accumulation within lubricants. Conversely, the low mileage means major drivetrain components such as the clutch, gearbox, and turbocharger have experienced less cumulative wear than would be typical, provided they have been serviced at appropriate calendar intervals rather than purely by odometer readings. Given the advisories raised on both front brake discs, prospective buyers should inspect these closely for surface pitting, lipping at the outer edge, and any uneven wear pattern, as well as checking that the front callipers are not binding and that the brake fluid has been changed within the last two years regardless of mileage, due to its hygroscopic nature. On a test drive, listen for any brake shudder or vibration through the steering wheel under moderate to firm deceleration, and observe whether the vehicle pulls to one side under braking, which would suggest a seized slide pin or hydraulic issue. A thorough check of brake pad material remaining on the front discs is also essential, as pitted rotors often correlate with pads nearing the end of their service life. Beyond the braking system, the age and low-mileage profile of this vehicle demands particular attention to time-sensitive degradation items. Tyres should be examined for sidewall perishing and cracking, as rubber compounds harden with age regardless of tread depth, and the manufacturing date on the sidewall should be checked to ensure none are older than six years. The 12-volt battery is likely approaching the end of its typical service life and should be load-tested, while the coolant, transmission fluid, and differential oil should be verified as having been replaced at calendar-based intervals rather than relying solely on odometer-triggered services. Finally, inspect all underbody seams, suspension bushes, coil springs, and exhaust hangers for standing corrosion, as low usage in damp conditions can promote oxidation on ferrous components even when mechanical wear remains minimal.
