2022 Mercedes-Benz CLA 1.3L Petrol · HL02 ARY

The most recent MOT test on 2026-03-09 resulted in a failure due to ineffective front windscreen wipers on both the offside and nearside, which is a critical failure category under DVSA standards. This outcome contrasts with the previous MOT results, where the vehicle passed in March 2025, indicating a deterioration in the windscreen wiper functionality. The failure of both wipers suggests a potential issue with either the wiper arms, blades, or their mechanical linkage, which could be exacerbated by prolonged standing or exposure to environmental conditions that degrade rubber components over time. The presence of minor windscreen damage—such as the stone chip on the offside front window—also warrants attention, as it may indicate a history of road debris impact, which could contribute to further structural or optical degradation if not addressed promptly. The vehicle’s recorded mileage of 40,960 miles at the time of the latest MOT is consistent with its age, approximately four years old, and aligns with an annual usage rate of around 10,240 miles, which is within the typical range for a car of this class. However, the gap between the 2025 MOT and the 2026 failure suggests the vehicle may have been stationary for a significant period, potentially allowing consumables like brake fluids and lubricants to degrade over time. Stationary vehicles are particularly vulnerable to issues such as brake disc corrosion, particularly if they have been left exposed to moisture or road salt, which can lead to rusting or binding of calipers. Additionally, the nearside rear tyre showing slight cracking or perishing indicates that extended periods without use can accelerate tyre degradation, even at lower mileage. Given the recurring advisories regarding brake disc wear and the failure of the windscreen wipers, the prospective buyer should conduct a thorough inspection of the braking system. Start by checking for uneven brake pad or disc wear, which could indicate misalignment or binding calipers. Listen for any grinding noises when braking, which may signal worn brake pads or metal-to-metal contact with the discs. Inspect the brake discs for signs of pitting, scoring, or corrosion, particularly on the nearside and offside rear, where advisories were noted. If the discs appear severely compromised, consider replacing them to prevent premature failure or safety risks. The windscreen wipers should be removed and inspected for wear on the rubber blades, which may have dried out or cracked over time. Test the wiper arms and linkages for smooth operation, as stiffness or binding could exacerbate the failure noted in the MOT. For the overall roadworthiness and long-term reliability, the buyer should also verify the condition of the vehicle’s suspension and steering components. Pay attention to the suspension bushes and coil springs for signs of excessive play or leaks, which could indicate wear or damage. On a test drive, listen for clunking noises from the suspension, particularly when driving over bumps or at speed, as this may signal failing bushings or damaged springs. Check for uneven tyre wear patterns, which could point to misalignment, suspension issues, or incorrect tyre pressures. The tyre tread depth should be verified, with a minimum of 1.6mm legally required, though deeper tread may be advisable for safety. Additionally, inspect the exhaust system for leaks or excessive noise, which could indicate wear in the catalytic converter or muffler. Finally, given the vehicle’s age and potential stationary periods, a comprehensive fluid check is essential. Top up or replace fluids such as brake fluid, coolant, and transmission fluid, as standing fluids can degrade over time. Ensure the 12-volt battery is in good condition, as prolonged disuse can lead to sulphation or reduced capacity. Lastly, verify that the service history is up to date, particularly for scheduled maintenance such as oil changes, timing belt replacement, and suspension servicing, which are critical for the vehicle’s longevity.
