2015 Mercedes-Benz Sprinter 2.1L Diesel · ND64 TXR

A recurring theme in the MOT record is the ongoing corrosion of the brake pipe system, which has been flagged in every test since 2021 and again in the most recent 2026 inspection, alongside a suite of secondary advisories that together suggest a vehicle whose core braking infrastructure is under persistent attack rather than a model of consistent cleanliness. The 2026 test was passed, yet it still listed an oil leak, near‑side rear service brake binding, corroded brake pipe, a minor flexi‑pipe exhaust leak and near‑side front inner tyre close to the legal limit, indicating that while the vehicle meets the legal minimum, the underlying issues have not been fully resolved. At 206,419 mi for a 2015 Sprinter the annual average is roughly 18,800 mi, well above the typical 10‑12 k mi per year for a light commercial chassis. The MOT history shows annual testing with no long gaps, implying continuous use rather than extended storage. Such mileage accelerates wear on suspension bushings, coil springs, drivetrain bearings and the brake wear surfaces that are already highlighted by the recurring pipe corrosion and tyre wear advisories, meaning the components are likely approaching the end of their service lives. The brake pipe corrosion warrants a thorough visual inspection of the entire line from the master cylinder to each wheel, looking for rust, pitting or grease‑filled deposits that could compromise sealing. On a road test, the driver should note any soft or spongy pedal feel, a gradual rise in pedal travel under steady braking, or any unusual noises such as squeal or grinding that could signal pipe leakage or fluid contamination. Replacing the affected sections or the whole pipe assembly, flushing the system and refilling with fresh DOT‑specified fluid would be prudent before relying on the vehicle for heavy loads. The oil leak advisory, rear brake binding, exhaust flexi‑pipe leak and front‑end wear items also merit targeted checks. Verify the engine bay for fresh oil stains around valve covers, oil pan or gasket joints, and monitor the oil level over a short drive to detect any loss. Test the rear brakes for pull or uneven pedal response that could stem from the binding service brake, and listen for a faint hissing or ticking from the exhaust flexi‑pipe under acceleration. Finally, assess the front steering by turning lock‑to‑lock and feeling for a slight knock or excessive play that could be linked to the off‑side tie‑rod and damaged shock absorber covers; ensure the near‑side front tyre is replaced or rotated promptly to avoid a sudden loss of grip.
