2014 Renault Master 2.3L Diesel · FJ14 FWL

The September 2025 test at 141,362 miles returned a pass, yet the record reveals a vehicle that deteriorated sharply in the months prior. The August 2025 failure at 141,359 miles was severe and wide-ranging, with excessive corrosion across both nearside and offside rear brake pipes, both rear brake hose ferrules, and both front brake pipes. The offside front brake hose was also excessively deteriorated, the offside front service brake was binding, and the engine management light indicated a malfunction. This represents a sudden plunge from clean passes in March and August 2024 with no recorded defects. The maintenance trend has worsened dramatically. Mileage accumulation has been modest and consistent, averaging roughly 11,780 miles annually over twelve years. Between August 2024 at 134,028 miles and August 2025 at 141,359 miles, the vehicle covered only about 7,300 miles. The February 2025 test at 141,224 miles sits awkwardly close to the later August and September dates, suggesting the owner sought testing after the initial 2024 pass revealed no issues, then encountered the cascade of brake failures within months. The low annual mileage for a commercial vehicle of this type could indicate intermittent use, which itself accelerates corrosion through lack of regular brake system exercise and moisture evaporation. The brake system demands thorough pre-purchase scrutiny. The pattern of multiple corroded pipes and hoses across both axles points to systemic neglect of the hydraulic circuit rather than isolated component failure. The binding offside front brake, recorded at the August 2025 failure, may have caused accelerated wear to both front discs, which the tester noted as worn though not yet excessive. A buyer should verify that all listed brake pipes, hoses, and ferrules were replaced with quality components, not merely patched, and that the binding caliper was stripped and serviced or replaced. The engine management light fault and the tyre perishing on the nearside rear, which persisted from the failure to the subsequent pass, require equal attention. The MIL fault could indicate emissions system degradation common to high-mileage Masters, while the cracked tyre suggests rubber ageing across the vehicle. The marker lamp and registration plate lamp defects, though minor, add to the impression of deferred upkeep. Prospective buyers should commission a full hydraulic brake inspection, an OBD diagnostic scan for active or pending engine codes, and close examination of all rubber components including tyres, hoses, and suspension bushes for perishing from age and irregular use.
