2006 Renault Master 2.5L Diesel · SO55 NMM

The most recent MOT test on 30 July 2026 resulted in a pass with no defects recorded, which follows a failed attempt just two days earlier on 28 July 2026. That failure was particularly serious, with three dangerous defects and one major defect. The dangerous items comprised both front tyres having a tread depth below the legal minimum of 1.6mm, and the parking brake efficiency falling below 50 percent of the required value. A major defect was also recorded for an ABS warning lamp indicating a fault in the anti-lock braking system. Although the subsequent pass demonstrates that the tyres and parking brake were addressed and the ABS issue was either resolved or downgraded to an advisory, the original advisory on the nearside front tyre from 2024 had already flagged edge wear, suggesting that suspension geometry, wheel alignment, or a tracking issue may be accelerating front tyre deterioration. The overall trend over the past two years shows intermittent failures interspersed with passes, indicating a maintenance pattern that is inconsistent rather than stable, and a prospective buyer should treat the cluster of brake and tyre defects as a meaningful warning sign regarding the vehicle's upkeep discipline. The recorded mileage of 151,935 miles on a vehicle of this vintage equates to an annual average of around 7,600 miles, which is broadly typical for a 2006 Renault Master of this age. There are no obvious extended gaps in the MOT history, with tests recorded annually from 2021 through to 2026, indicating fairly continuous use. However, mileage consistency across decades of MOT records cannot be fully verified from the data provided, so it is prudent to confirm the figure against the odometer at the time of viewing and to cross-reference it with service book stamps and any available V5C documentation. Given the cumulative wear expected at nearly 152,000 miles, the mechanical implications include accelerated degradation of clutch components if it is a manual, wear within the dual-mass flywheel if fitted, higher likelihood of turbocharger wear on diesel variants, and general fatigue within engine and gearbox mounts. Routine replacement intervals for cambelts, water pumps, and coolant should be checked thoroughly against the manufacturer's schedule, as these are critical on Renault Master diesel units. Looking more closely at the recurring defects recorded across the MOT history, several areas warrant focused physical inspection and careful attention on a test drive. The persistent front tyre edge wear, first noted as an advisory in 2024 and culminating in a dangerous failure on both fronts in 2026, strongly suggests an underlying suspension or steering geometry issue. On a test drive, listen for any clonking or knocking from the front suspension over uneven surfaces, particularly on speed humps and rough roads, and pay particular attention to worn or perished suspension bushes, top mounts, drop links, and coil springs, all of which are common wear points on a vehicle of this age and mileage. Steering play, vague off-centre behaviour, or uneven inner-edge tyre wear would indicate the need for tracking adjustment or replacement of worn wishbone bushes or tie bar components. The major defects in 2024 relating to the nearside front seat belt anchorage and excessively corroded rear brake hose ferrules are also significant, as corroded brake hose ferrules can compromise hydraulic integrity, and although presumably rectified, the surrounding pipework and unions should be visually inspected for further corrosion, particularly around the rear axle and underbody. The ABS warning lamp issue from the 2026 failure requires confirmation that the dashboard warning lamp extinguishes on a cold start and that the system passes a proper diagnostic scan, as persistent ABS faults can indicate wheel speed sensor failure, reluctor ring corrosion, or deeper hydraulic control unit concerns. The 2023 advisory noting an offside rear service brake binding but not excessively is another item that should not be overlooked, as binding calipers or seized handbrake mechanisms are a known issue on commercial vehicles that frequently stand for long periods or undertake heavy loading cycles. On a test drive, confirm that the vehicle rolls freely when released with the handbrake off, that there is no heat emanating from the rear wheels immediately after a short drive, and that the handbrake holds the vehicle on a slope without excessive lever travel. Given the age of the vehicle at twenty years, age-related degradation must also be considered regardless of the recorded mileage, including tyre sidewall perishing and cracking from UV exposure, brake disc corrosion and lip formation from standing, time-based degradation of brake fluid and engine coolant which should have been replaced at least every two to four years, condition of the 12V battery which typically requires replacement on a four to five year cycle, and deterioration of rubber components throughout the cooling, fuel, and vacuum systems. The underside should be inspected on a ramp for structural corrosion to the subframes, sills, outriggers, and load floor, all of which are common failure areas on Renault Masters of this generation, particularly those used for commercial duty over many years.
