2015 Mercedes-Benz CLA 2.1L Diesel · LL65 WMM

The most recent MOT test on the 2015 Mercedes-Benz CLA, conducted on 2026-09-01, has not yet been recorded in the provided history, but the preceding tests reveal a pattern of persistent but manageable mechanical and functional advisories. The vehicle’s MOT history shows a mix of passed and failed tests, with failures primarily related to brake system wear, tyre integrity, and lighting faults. Notably, the most recent advisory failures from 2023 and 2024 centred on brake pad thickness and front brake disc scoring, alongside recurring issues with tyre sidewall damage and offside rear direction indicators. While the vehicle has passed subsequent tests, the consistent presence of these advisories—particularly the brake-related defects—suggests a gradual but steady progression in wear, indicating that the owner should prioritise proactive maintenance rather than waiting for further MOT failures. The absence of major defects or structural issues in the MOT records suggests the vehicle remains roadworthy, but the cumulative advisories warrant careful attention to prevent escalation into more costly repairs. The recorded mileage of 78,964 miles for a vehicle aged approximately 11 years represents a moderate annual usage rate of around 7,179 miles, which is within the expected range for this class of car. This usage profile does not suggest either excessive wear from high mileage or prolonged idleness, which could otherwise accelerate corrosion or fluid degradation. However, the presence of tyre sidewall cracking on the nearside rear tyre from the 2025 MOT advisory, combined with the earlier deep cut failure, implies that the vehicle has been subjected to some degree of road surface irregularities or aggressive cornering. Such sidewall damage can compromise tyre integrity over time, increasing the risk of blowouts or premature tyre failure, particularly if the vehicle is driven at higher speeds or on rough roads. Additionally, the consistent brake advisories, particularly the thin pad wear and scored discs, may reflect either regular braking habits or potential misalignment issues that could exacerbate wear if not addressed. For the prospective buyer, the most critical areas to inspect during a physical examination and test drive are the brake system, tyres, and lighting components. Begin with a thorough inspection of the brake discs and pads, focusing on the offside rear and nearside front areas where the most significant wear has been recorded. Listen for any unusual brake pedal vibration, shuddering, or sponginess during braking, which could indicate warped discs or binding calipers. Inspect the brake fluid reservoir for contamination or contamination levels, as brake fluid absorbs moisture over time, reducing effectiveness. Check for any signs of fluid leaks around the brake master cylinder, calipers, or wheel bearings, which could suggest failing seals or worn components. The tyres should be scrutinised for uneven wear patterns, which may signal alignment or suspension issues, and ensure the sidewall cracks from the 2025 MOT advisory have not worsened. Test the vehicle’s lighting system, particularly the dipped beam headlamps and direction indicators, to confirm they function correctly and that the offside rear indicators are emitting the correct amber colour. Beyond the immediate advisories, the buyer should also address the broader maintenance needs of the vehicle, particularly given its age and the moderate mileage. Given the 11-year age, the 12V battery should be tested for strength and replaced if it exhibits signs of weakness, such as slow cranking or dim headlights. Check for any standing corrosion on the undercarriage, especially around the wheel arches, exhaust system, and underbody components, as prolonged idleness can accelerate rust formation. Inspect the suspension components for signs of wear or damage, such as cracked or seized suspension bushes, coil spring failure, or excessive play in the control arms. The exhaust system should be checked for leaks or excessive noise, which could indicate catalytic converter or muffler issues, and emissions performance should be considered if the vehicle is to be used on roads with strict emissions regulations. Finally, since the vehicle has not had a full service in the last 12 months, it is advisable to verify the service book for the last scheduled oil change, filter replacement, and fluid top-ups, as these tasks are critical for maintaining engine and transmission longevity. If the service history is incomplete, consider arranging a comprehensive service to address any time-based fluid degradation, such as brake and differential fluids, which should be replaced every 60,000 to 100,000 miles or every 2 to 3 years, whichever comes first.
