2016 Mercedes-Benz GLA 2.1L Diesel · FP66 AAZ

The most recent MOT test on this 2016 Mercedes-Benz GLA, conducted on 2025-11-06, resulted in a passing outcome despite the presence of multiple advisories, particularly concerning the braking system. However, the preceding MOT on 2025-11-06 also failed due to the same advisories, alongside a major failure for a fractured offside rear coil spring, which indicates a critical structural and roadworthiness issue that must be addressed immediately. The pattern from the MOT history suggests a recurring problem with brake component wear and a severe, unresolved issue with the rear suspension coil spring, which has not been rectified between tests. This trend points to either inadequate maintenance or underlying mechanical wear that has not been properly managed, warranting urgent attention to prevent further deterioration. The vehicle’s recorded mileage of 73,074 miles over approximately ten years represents an average of around 7,307 miles per annum, which is consistent with typical usage for this age and model. While this mileage is not exceptionally high for a ten-year-old car, it does not necessarily indicate excessive wear if the vehicle has been driven in a moderate manner without prolonged periods of inactivity. However, the presence of a fractured coil spring at 73,074 miles raises concerns about potential fatigue or pre-existing structural stress, particularly if the vehicle has been subjected to rough road conditions or heavy loads. The advisories regarding brake pad and disc wear, especially at this stage, may also suggest that the braking system has been underutilised or that the vehicle has been driven in a manner that has accelerated wear beyond normal expectations. For the prospective buyer, the most pressing concern is the major failure of the offside rear coil spring, which has been identified as fractured. This defect compromises the vehicle’s structural integrity and stability, posing a safety risk if not repaired promptly. Immediate inspection should focus on the rear suspension system, including the condition of the remaining coil springs, shock absorbers, and struts, as well as the alignment and balance of the wheels. Listen for any unusual noises from the rear suspension during a test drive, such as clunking or rattling when driving over bumps, which may indicate further suspension wear or misalignment. Additionally, check for uneven tyre wear patterns, which could signal misalignment or suspension issues. The advisories regarding brake pad and disc wear, particularly if they persist, suggest that the braking system may require adjustment or replacement of components, including brake pads, discs, and calipers. Inspect the brake system for signs of binding, excessive heat damage, or fluid leaks, and test the braking performance under various conditions to ensure consistent and responsive stopping. Beyond the immediate mechanical concerns, the vehicle’s age and mileage warrant a thorough inspection of other critical components that may have degraded over time. Given the advisories of tyre cracking or perishing, particularly on the rear tyres, examine the sidewall condition for signs of dry rot, which can compromise tyre integrity and safety. Check the tyre tread depth and ensure they remain above the legal minimum. The advisories of obscured engine and floor covers suggest that components beneath the vehicle may be inaccessible for inspection, so visually confirm that no critical parts, such as exhaust manifolds or drivetrain components, appear corroded or damaged. The brake discs, in particular, should be closely inspected for signs of warping, grooving, or excessive pitting, which could lead to reduced braking efficiency or failure. For the rear brakes, listen for any grinding or squealing noises when applying the brakes, which may indicate worn pads or damaged discs. Finally, consider the condition of the 12V battery, as prolonged inactivity or low mileage can lead to battery degradation or corrosion, which may require replacement if the battery is old or shows signs of weakness. Additionally, check the fluid levels and condition of the engine oil, transmission fluid, and brake fluid, ensuring they are within specification and free from contamination. Given the vehicle’s age, a service history check would be beneficial to confirm compliance with manufacturer-recommended maintenance intervals, particularly for fluid servicing and component replacements.
