2020 Mercedes-Benz CLA 1.3L Petrol · LS20 ABF

The most recent DVSA examination on 15 October 2025 resulted in a Pass, with two advisories issued concerning the braking system and one minor defect recorded for the front wiper blades. Both advisories relate to the rear axle, specifically worn rear brake discs and rear brake pads thinning on both sides, while the minor defect centred on deteriorated wiper blade elements affecting both front arms. Although none of these items constituted a failure, the recurrence of brake-related advisories across multiple test cycles suggests a consistent pattern of wear rather than an isolated finding. Notably, the 2024 examination featured advisories for front brake discs and pads wearing thin, front and rear brake disc wear, and edge wear on two tyres, indicating that brake component deterioration has been an ongoing maintenance consideration for at least the past two MOT cycles. The overall trend is therefore one of stable but progressively declining condition in the braking and tyre arenas, which warrants close attention from any prospective purchaser. The recorded odometer reading of 62,594 miles over a six-year life equates to approximately 10,432 miles annually, which sits squarely within the typical usage envelope for a privately operated vehicle of this age and class. The MOT intervals, with tests recorded in June 2023, September 2024, and October 2025, imply a fairly continuous service history without obvious prolonged periods of standing or significant gaps between examinations. This regular usage pattern is mechanically advantageous as it reduces the likelihood of calendar-related degradation issues such as seized brake calipers from inactivity, perishing of rubber components, or flat spots in tyres. However, the mileage is sufficient to have placed meaningful wear on consumable braking components and suspension ancillaries, which is reflected in the advisory history. For a prospective buyer, the most pressing area for inspection is the braking system in its entirety. Given that rear discs and pads were flagged as thinning in late 2025, it is reasonable to anticipate that replacement of rear brake pads, and possibly the rear discs, may be due imminently, with the front discs and pads likely to follow suit based on the prior advisory trend. On a test drive, any signs of brake shudder through the steering wheel or pedal, prolonged pedal travel, or a grinding or squealing noise under light application would confirm that component wear has progressed beyond the advisory threshold. The brake fluid itself, irrespective of the brake wear pattern, should be assessed for age; Mercedes-Benz typically specifies a biennial fluid change, and a six-year-old vehicle should have evidence of at least two or three fluid services in the service book, with attention given to spongy pedal feel or discoloured fluid when the master cylinder cap is removed. Beyond the braking system, the recurring advisory on the offside front anti-roll bar link ball joint from the 2023 test should prompt a targeted inspection of the front suspension. Anti-roll bar links are prone to progressive wear that accelerates once initial play is detected, so a road test should include driving over uneven surfaces, speed humps, and through tight corners while listening for clonks or knocks from the front suspension, particularly over undulating tarmac. Given the tyre advisories recorded for edge wear on both the offside rear and nearside front in 2024, a four-wheel alignment check is strongly advisable, as uneven shoulder wear typically indicates geometry drift rather than simple inflation issues. Finally, while the mileage is not excessive, attention should be directed towards age-related items including the 12-volt battery state of health, coolant and transmission fluid service history, and any signs of exhaust corrosion, particularly around mounting points and the rear silencer, all of which constitute prudent due diligence for a Mercedes-Benz of this vintage.
