2016 Renault Master 2.3L Diesel · HY66 WRR

A recurring electrical advisory regarding the supplementary restraint system warning lamp presents the primary mechanical concern for this Renault Master, as this issue has appeared intermittently across multiple testing cycles, most recently on 27 February 2026. While the vehicle achieved a pass in its latest inspection, the persistent failure of the SRS lamp to illuminate suggests a fault within the airbag monitoring circuit or a faulty indicator bulb that has remained unresolved since at least September 2023. This pattern, combined with a previous major failure for a missing rear registration plate in September 2023, indicates that while the vehicle is structurally and mechanically capable of passing, certain non-safety-critical electrical and external trim items have been overlooked during maintenance intervals. The vehicle's mileage profile is consistent with a moderate usage pattern, having covered 69,482 miles over its ten-year lifespan. This equates to an average annual accumulation of approximately 6,948 miles, which is relatively low for a commercial vehicle of this type. Mechanically, this suggests the engine and drivetrain have not been subjected to the high-frequency heavy loading or high-mileage wear typical of long-distance courier work. However, lower annual mileage can sometimes lead to more frequent short-trip cycles, which may impact the condition of the diesel particulate filter or battery health, though the MOT records do not specifically flag any emissions or starting issues. Prospective buyers should prioritise a thorough investigation of the SRS system to ensure the airbag deployment circuit is fully functional and that the warning lamp issue is not indicative of a deeper fault within the airbag control module. During a test drive, pay close attention to the windscreen, as the records show a recurring chip in the central front area, which was noted as a minor defect in both 2024 and 2026. While currently deemed not to adversely affect the driver's view, such chips can propagate into larger cracks under thermal stress or vibration, potentially necessitating a full glass replacement. Beyond the electrical and glass concerns, the vehicle's relatively low mileage means that while major mechanical wear on suspension bushes or brake discs may be lower than average, the vehicle should still be inspected for any signs of age-related degradation. Ensure that all exterior lighting and registration plate mounting points are secure and compliant to avoid a repeat of the 2023 failure. Given the consistent pass rate for the core mechanical components, the primary focus should remain on resolving the documented electrical advisory and verifying the integrity of the windscreen.
