2016 Renault Master 2.3L Diesel · HT16 OMD

The vehicle most recently passed its MOT on 25 September 2025 with no defects recorded, which suggests that the issues identified during the failed test two weeks prior have been rectified. However, the overall maintenance trend appears somewhat reactive rather than proactive, as evidenced by the failure in September 2025 involving lighting and washer systems, as well as the significant failure in August 2024 regarding exhaust security and body damage. While the most recent result is clean, the history of multiple failures for electrical components and structural/exhaust issues indicates a pattern of addressing defects only when they reach the threshold of an MOT failure. With 161,837 miles recorded over approximately ten years, this Renault Master has averaged roughly 16,000 miles per year. This is relatively high usage for a commercial vehicle of this age, suggesting it has been used regularly for long-distance or heavy-duty transit. Such high mileage places significant cumulative stress on the drivetrain, suspension, and braking systems. You should anticipate that major components such as the turbocharger, clutch assembly, and fuel injection system may be approaching the end of their service life, and the high mileage necessitates a very thorough verification of the service history to ensure oil changes and timing belt replacements have been carried out according to manufacturer intervals. During your test drive, pay close attention to the braking performance and the condition of the rear brakes. The September 2025 advisory noted that the rear brake pads were wearing thin, and while this may have been addressed, you should check for any uneven deceleration or a pulsating sensation through the pedal which could indicate warped discs or binding calipers. Given the previous failure regarding the offside front constant velocity boot, listen closely for any rhythmic clicking or popping noises when turning the steering wheel at low speeds, as this is a classic symptom of a failing drive shaft joint. Furthermore, inspect the underside of the vehicle for signs of exhaust corrosion or loose mounting brackets, following the major failure recorded in 2024. General mechanical scrutiny should also extend to the electrical and fluid systems. The recurring issues with marker lamps, indicators, and headlamp aim suggest that the electrical loom or bulb housings may be prone to moisture ingress or corrosion. Check that all exterior lighting functions correctly and that the windscreen washer system operates with sufficient pressure. Because of the high mileage and age, you should also inspect the suspension bushes and coil springs for signs of excessive wear or perished rubber, which would manifest as clunks or knocks over bumps. Finally, verify the service book for evidence of regular fluid changes, as high-mileage diesel engines are particularly sensitive to oil quality and fuel system cleanliness.
