2010 Mercedes-Benz B-Class 1.5L Petrol · DF10 EXV

The most recent MOT test on the 2010 Mercedes-Benz B-Class recorded a clean pass on 2026-08-11, marking a significant improvement from the previous test results. While the vehicle has passed the latest inspection without any defects, the MOT history reveals a concerning pattern of recurring issues with the braking system, particularly the brake pipes and discs, which have consistently failed or been flagged as deficient in multiple tests over the past five years. The failure in 2026-07-10 was particularly severe, with dangerous defects including a leaking brake pipe and extensive corrosion on both front-to-rear sides, indicating a critical failure in the hydraulic braking system. This suggests that the vehicle has either been neglected in addressing prior advisories or has been subjected to conditions that accelerate corrosion and fluid degradation, warranting immediate attention to prevent further deterioration or a repeat failure. The recorded mileage of 63,513 miles for a vehicle aged approximately 16 years represents a relatively low annual usage rate of around 3,970 miles per year, which is unusually low for a car of this age and model. Such low mileage often correlates with prolonged periods of inactivity, particularly if the vehicle has been stored for extended periods without regular use. However, this usage profile can mask underlying issues, as standing vehicles are prone to accelerated wear in critical components such as brakes, suspension, and fluid systems due to corrosion, condensation, and fluid degradation. The consistent advisories on brake pipe corrosion, despite low mileage, imply that the vehicle may have been stored in damp or poorly ventilated conditions, which exacerbates rust formation and fluid breakdown. Additionally, the presence of grease on the corroded pipes suggests prior attempts at mitigation, potentially indicating a lack of proactive maintenance. Given the recurring MOT advisories on brake pipe corrosion and the critical failure in 2026-07-10, the prospective buyer should prioritise a thorough inspection of the braking system. The brake pipes should be visually inspected for any signs of further corrosion, cracks, or leaks, with particular attention to the front-to-rear sections where defects were previously noted. During a test drive, listen for any unusual noises such as grinding or squeaking from the brakes, which could indicate worn brake pads, warped discs, or binding calipers. Additionally, check for uneven brake pedal travel or a spongy feel, which may signal air in the hydraulic system or failing brake master cylinder components. The buyer should also verify that the brake fluid level is adequate and that there are no visible leaks around the brake lines or master cylinder. If the brake pipes are found to be severely corroded or compromised, immediate replacement of the affected sections is essential to restore safe braking performance. For the remaining components, the buyer should conduct a comprehensive physical examination of the vehicle, focusing on areas prone to long-term degradation despite low mileage. The tyres, particularly those with sidewall cracking or perishing, should be inspected for signs of dry rot or internal damage, as this can compromise tyre integrity and safety. Check the tyre tread depth and look for irregular wear patterns, which may indicate alignment or suspension issues. The suspension should be tested for any signs of binding, excessive play, or unusual noises such as clunks or rattles, which could suggest worn suspension bushes, coil springs, or damaged control arms. The battery should be checked for corrosion on terminals and a functional test to ensure it holds a charge, as standing vehicles are prone to battery drain and corrosion. Finally, since the vehicle’s age and usage profile suggest potential fluid degradation, the buyer should verify that the coolant, brake fluid, and transmission fluid are within specification and have not been contaminated or degraded over time. If possible, obtaining a service history or service book would provide further insight into the vehicle’s maintenance record and help confirm whether prior advisories were addressed.
