2016 Mercedes-Benz C 2.1L Diesel · BJ66 WBP

The most recent MOT test on 2026-05-29 resulted in a passing outcome, marking a positive turnaround from the vehicle’s previous failures. However, the history reveals a pattern of recurring critical issues, particularly with the front coil springs and rear brake components, which have consistently led to major or dangerous failures across multiple tests. The most recent failure in 2025-04-23 highlighted a fractured offside front coil spring and severe wear to the rear brakes, including pads below the legal minimum thickness and a significantly worn rear brake disc. Although the 2026-05-29 test passed, the presence of advisories from 2024-05-21—such as worn but not excessively thin brake discs and thinning pads—suggests ongoing wear progression that may not yet have reached critical levels but warrants close monitoring. The vehicle’s MOT history does not show a clear improvement trend; instead, it reflects persistent mechanical stress, particularly in suspension and braking systems, which may indicate underlying issues such as excessive load, poor maintenance, or inherent component fatigue. The vehicle’s recorded mileage of 84,355 miles at the time of this assessment is consistent with its age, approximately 10 years old, and aligns with an annual usage rate of around 8,436 miles. This rate is typical for a car of this age, though it does not necessarily indicate heavy or light usage—it could reflect a mix of regular driving, occasional long trips, or periods of prolonged standing. However, the presence of multiple MOT failures, especially those tied to suspension and braking systems, suggests that the vehicle has undergone significant wear over time. If the mileage accumulation was rapid or accompanied by heavy loads, this could accelerate component degradation, particularly in high-stress areas like coil springs and brake components. Conversely, if the vehicle has been driven at a more moderate pace with fewer high-mileage events, the wear pattern may still be influenced by factors such as poor maintenance or inherent material fatigue. Given the vehicle’s MOT history, the buyer should prioritise a thorough inspection of the suspension and braking systems. On a test drive, listen for unusual noises such as clunking or rattling from the front suspension, which could indicate loose or damaged coil springs or bushings. Check for uneven tyre wear, particularly on the rear tyres, which may suggest brake drag or misalignment caused by worn discs or pads. Inspect the rear brakes for any signs of pulsation or vibration during braking, which could indicate warped discs or binding calipers. Additionally, visually inspect the coil springs for any signs of further deterioration, such as sagging or excessive movement, which could compromise ride quality and safety. The buyer should also verify that the rear brake discs are not warped or scored, as this can lead to reduced braking performance and increased heat buildup. If the vehicle has been stationary for long periods, check for standing corrosion on the brake discs, calipers, and suspension components, as this can exacerbate wear and reduce structural integrity. For the buyer, given the vehicle’s age and mileage, a comprehensive physical inspection is essential beyond the MOT test results. Start by examining the tyres for sidewall cracking or perishing, which can occur even at moderate mileages due to ageing rubber. Check the tyre tread depth, ensuring it meets the legal minimum of 1.6mm across the central ¾ of the tread, and look for signs of uneven wear that may indicate alignment or suspension issues. Inspect the 12V battery for signs of corrosion on terminals and cables, and test its charge capacity to ensure it is not failing prematurely. Given the vehicle’s age, the brake fluid should be checked for contamination or moisture, as this can lead to brake system failure. The coolant should also be inspected for colour and clarity, with a recommendation to replace it if it appears old or has degraded. Finally, verify that all service records are up to date, particularly for the suspension and braking systems, as these have been recurring failure points. If the vehicle has not been serviced recently, consider scheduling a professional inspection to address the coil spring and brake wear before it escalates into more costly repairs.
