2016 Mercedes-Benz CLA 2.1L Diesel · LS16 XHM

The latest MOT test for this 2016 Mercedes-Benz CLA, conducted on 2025-09-30, resulted in a clean pass with no recorded defects. However, the preceding MOT history reveals a pattern of recurring advisories and minor failures, particularly around the front anti-roll bar linkage ball joint dust cover deterioration and rear seatbelt functionality, which were noted in 2024. The failure in 2024-10-09 for the near-side front headlamp aim too low, alongside the persistent advisories on tyre wear and brake condition, suggests that while the vehicle has maintained roadworthiness, there are underlying mechanical issues that require closer attention. The trend over the past three years does not appear to be worsening dramatically, but the presence of these advisories indicates that the vehicle has not been fully serviced or maintained to the manufacturer’s specifications, particularly in areas like suspension components and brake systems. The recorded mileage of 84,527 miles for a vehicle aged approximately ten years represents a moderate annual usage rate of around 8,453 miles per year, which is typical for its class and age. This level of usage does not necessarily indicate excessive wear beyond normal expectations, but it does mean that consumables such as brake pads, tyres, and suspension components have accumulated significant mileage. The advisories on near-side rear tyre wear close to the legal limit and front brake pad thinning suggest that the braking system has been subjected to prolonged use, potentially leading to uneven wear patterns or reduced braking efficiency if not addressed soon. Additionally, the distortion of the offside rear inner road wheel and pitted brake discs indicate that the vehicle has experienced some stress on these components, warranting inspection for structural integrity and potential alignment issues. For the prospective buyer, the most critical areas to inspect during a physical examination and test drive are the suspension and braking systems. The severely deteriorated near-side front anti-roll bar linkage ball joint dust cover from the 2024 MOT should be replaced promptly, as the exposed joint could lead to premature wear of the ball joint itself, clunks or rattles when driving over bumps, and potential misalignment of the anti-roll bar. Listen for a metallic clunking noise when the vehicle is driven over rough roads, and check for uneven suspension travel or binding in the front suspension components. The slow retraction of the offside rear seatbelt, also noted in 2024, may indicate a faulty seatbelt retractor mechanism, which could pose a safety risk in a crash; this should be repaired immediately. Regarding the brakes, inspect the front discs and pads for signs of glazing, warping, or excessive thickness loss, and listen for a grinding noise when applying the brakes, which could signal worn pads or damaged discs. The worn tyres and pitted brake discs suggest that the vehicle should have its brake system serviced, including pad and rotor replacement if necessary, to restore optimal braking performance. In terms of broader maintenance and physical checks, given the vehicle’s age and mileage, the buyer should verify the condition of the tyres beyond the legal limits, checking for sidewall cracking or perishing, which can compromise tyre integrity and safety. The brake fluid should be flushed and replaced every two years or 40,000 miles, as old brake fluid can absorb moisture and reduce braking effectiveness. Inspect the exhaust system for leaks or corrosion, particularly around the catalytic converter and mufflers, as the Mercedes-Benz CLA is known to develop rust issues in standing positions. The 12-volt battery should be tested for voltage output and overall health, especially if the vehicle has been stored for extended periods, as standing corrosion can affect electrical systems. Finally, ensure that the service history is up to date, particularly for fluid changes, timing belt replacement (if applicable), and any suspension or brake work, as the advisories suggest some areas may have been neglected. A thorough inspection of the vehicle’s undercarriage for signs of oil leaks, coolant leaks, or structural damage is also advisable, as the combination of mileage and advisories points to potential wear in these critical systems.
