2014 Mercedes-Benz Sprinter 2.1L Diesel · OU14 AOW

The most recent MOT inspection on 06 March 2026 resulted in a pass, but the vehicle's maintenance profile shows a concerning downward trend regarding the braking system. While the vehicle passed, the recurring advisories concerning corrosion on the nearside rear, offside rear, and central rear brake pipes indicate a progressive deterioration of the hydraulic lines. The history shows a significant failure in January 2025 due to an excessively binding offside rear service brake, which, combined with the persistent advisories for pitted and scored brake discs, suggests that the rear braking assembly has been subject to ongoing neglect or environmental degradation. Although the status is currently a pass, the repetition of these specific defects indicates that the underlying issues are not being rectified, but merely monitored, which points toward an impending requirement for significant remedial work. With a recorded mileage of 63,190 miles over approximately twelve years, this Mercedes-Benz Sprinter has averaged roughly 5,266 miles per year. This is exceptionally low mileage for a commercial vehicle of this age and type, which often implies the vehicle has been used for short journeys or has spent considerable periods stationary. While low mileage generally suggests less wear on the engine and drivetrain, it presents specific mechanical risks. Long periods of standing can lead to the degradation of rubber components, such as suspension bushes and tyre sidewalls, and can cause fluid breakdown or moisture accumulation within the braking system and engine oil. The corrosion noted on the brake pipes is a classic symptom of a vehicle that has been exposed to moisture without the regular heat cycles and airflow that higher-mileage driving provides to help dissipate contaminants. During your test drive, you must pay close attention to the braking performance and the condition of the rear axle area. Listen for any grinding or squealing noises from the rear wheels, which could indicate that the pitted brake discs or the binding caliper issue from the previous failure have worsened. Check for any pulsation or shudder through the brake pedal when applying pressure, as this often signals warped or unevenly worn discs. You should also inspect the underside of the vehicle for any signs of active fluid leaks from the brake pipes or the power steering system, as the history previously noted seepage from the pump to the rack. Any sign of weeping hydraulic fluid near the rear brake lines would indicate that the corrosion has progressed to a point of structural failure, necessitating immediate replacement of the lines to ensure roadworthiness. Given the low annual mileage, a thorough physical inspection of age-related wear is essential. Examine the tyres for sidewall cracking or perishing, which occurs when rubber loses its elasticity due to age rather than tread wear. Check the condition of the 12V battery, as infrequent use can lead to sulphation and reduced cranking power. You should also verify the service history to ensure that oil and coolant changes have been performed on a calendar basis rather than just a mileage basis, as fluids degrade over time regardless of distance travelled. Finally, inspect the power steering components and hoses for any renewed seepage, as the previous advisories suggest this area remains a potential point of failure. Ensure the service book contains evidence of regular maintenance to mitigate the risks associated with this vehicle's specific usage profile.
