2020 Mercedes-Benz CLA 1.3L Petrol · LS20 OMP

The most recent MOT test for this 2020 Mercedes-Benz CLA, conducted on 2025-11-29, resulted in a clean pass with no recorded defects, marking a notable improvement in its roadworthiness status. While the vehicle’s previous MOT history from 2023 onwards was initially clean up until June 2023, the failure in that month—where both front inner brake pads were found to be dangerously thin at under 1.5 mm—suggests a significant maintenance lapse or a failure to address prior wear. The subsequent MOTs in 2024 and 2025 passed without defects, indicating either timely brake pad replacement or effective wear management, though the history does not reflect a consistent, proactive maintenance schedule. The presence of a single failure point in 2023, rather than a pattern of recurring issues, leans towards a one-off incident rather than systemic neglect, but the buyer should remain vigilant about brake system integrity moving forward. The vehicle’s recorded mileage of 50,478 miles over six years represents an average annual usage of approximately 8,413 miles, which is within the expected range for a car of this age and class. Lower mileage could imply periods of inactivity, potentially leading to issues such as standing corrosion on brake components, suspension bushes, or exhaust system seals, which can degrade more rapidly when a vehicle is not in use. Conversely, higher mileage would accelerate wear on consumables like brake pads, suspension bushings, and drivetrain elements, but 8,413 miles per year is not excessively high for a six-year-old car, particularly if the vehicle is driven in mixed conditions rather than solely in light traffic. The absence of rapid mileage accumulation suggests the owner has likely maintained a steady, moderate usage pattern, though the brake failure in 2023 could have been exacerbated by either infrequent driving or a lack of routine brake inspections. Given the brake failure in June 2023, the buyer must prioritise a thorough inspection of the braking system, focusing on the front inner brake pads, discs, and calipers. The DVSA failure indicates that the pads were dangerously worn, which could have led to uneven wear on the discs, potential binding of the calipers, or even warping if the vehicle was driven heavily. During a test drive, listen for any abnormal braking noises—such as grinding, squeaking, or a pulsating sensation in the pedal—which may signal disc warping, caliper binding, or remaining pad material. Additionally, check for uneven tyre wear, which could imply brake drag or misalignment. Immediate replacement of the front inner brake pads is strongly advised, and the buyer should also inspect the outer pads and rear brakes for similar wear. Beyond the brakes, examine the suspension for any signs of excessive play or clunking, particularly around the front suspension bushes and coil springs, as these can degrade with age and mileage. For the broader vehicle assessment, the buyer should conduct a comprehensive physical inspection beyond the MOT scope, given the vehicle’s age and mileage. Start with the tyres, checking for sidewall cracking or perishing, which can occur even with moderate mileage if the rubber has been exposed to prolonged sunlight or poor storage conditions. Verify the tread depth is legal and consider rotating the tyres to ensure even wear. Inspect the 12V battery for corrosion around terminals, a common issue in stationary vehicles, and test its charge capacity by attempting to start the engine or using a multimeter. The battery should hold a charge without excessive strain, and if it fails, consider replacing it before it leads to electrical system failures. Fluid checks are critical due to the vehicle’s age; the coolant should be fresh and free of contaminants, the brake fluid should be clear and not discoloured (indicating moisture or contamination), and the differential and transmission fluids should be topped up to manufacturer specifications. Finally, verify that the service book or maintenance records are up to date, particularly for timing belt replacement (if applicable) and other time-based servicing, as Mercedes-Benz typically recommends these at 60,000–100,000 miles or every 60 months. If the service history is incomplete, schedule a professional inspection to address any outstanding items, especially given the brake history.
