2009 Mercedes B-Class 2.0L Diesel · FL09 OOA

This 2009 Mercedes B-Class has a very low mileage profile, averaging just over 3,500 miles per year. While this suggests light use, such low annual mileage can sometimes lead to issues like seized components or corrosion due to the vehicle sitting idle for extended periods. The most recent MOT from March 2026 shows a pass, but it highlights a concerning and recurring mechanical pattern regarding the braking system. Corrosion on the rear brake pipes was noted in January 2025 and has reappeared in the most recent test. This indicates that the issue is not being fully resolved or that the corrosion is spreading. The vehicle's condition trend appears to be worsening. We have moved from steering rack and tyre issues in previous years to persistent, recurring corrosion in the brake lines and new advisories regarding anti-roll bar linkages and wiper blades. The progression from a failed MOT in early 2025 to multiple advisories in 2026 suggests a gradual decline in the maintenance of the chassis and braking components. The low mileage is an ambiguous signal; it may mean the car has been well-kept, but the recurring brake pipe corrosion is a significant safety risk that often accompanies vehicles that are not driven frequently enough to keep components clear of moisture and debris. Before purchasing, you must inspect the condition of the rear brake pipes thoroughly to ensure they have been properly replaced rather than just cleaned, and check the integrity of the steering rack and anti-roll bar components.
