2022 Renault Master MM35 B-Ness Energy DCI 2.3L Diesel · OU22 ABZ

The most recent official DVSA test, conducted on 10 March 2026, resulted in a pass with a single minor advisory noting windscreen damage that does not currently impede the driver's view. While the vehicle is mechanically roadworthy, this minor record should not be dismissed entirely, as any windscreen damage has the potential to develop into a more serious defect if the crack spreads, particularly given the stresses imposed on large glazed panels in commercial vehicles such as the Renault Master. The prior test on 27 March 2025 yielded a clean pass with no advisories, though an earlier test on the same date recorded a major failure relating to the nearside windscreen wiper failing to clear the windscreen effectively. The fact that this failure was rectified and resulted in a clean pass shortly afterwards indicates a competent response to repair, and the absence of any recurring suspension, brake, lighting, or structural advisories across the documented history suggests the vehicle has maintained a generally stable roadworthiness profile rather than exhibiting any deteriorating pattern. With a recorded mileage of 17,415 miles over an approximate four-year service life, this Master averages around 4,354 miles annually, which is notably low even for a commercial vehicle. Such low annual usage typically points to extended periods of standing rather than consistent light-duty operation, and this carries distinct mechanical implications. Long idle periods can accelerate corrosion on brake discs due to surface oxidation, lead to binding or seized caliper pistons from infrequent actuation, and degrade the 12-volt battery through sustained low-charge cycles. Conversely, the relatively low mileage means that major drivetrain components such as the clutch, turbocharger, and diesel particulate filter have not been subjected to heavy wear, though the latter can be particularly susceptible to soot accumulation during short, infrequent journeys that prevent passive regeneration. Given the sparse MOT history and the low cumulative mileage, the prospective buyer should approach this vehicle with attention to age-related degradation rather than focusing solely on wear-based concerns. The tyres warrant a thorough physical inspection for sidewall perishing and cracking, as rubber compounds deteriorate with calendar age regardless of tread depth, and a commercial vehicle standing for prolonged periods often develops flat spots or uneven pressure distribution. The brake discs and calipers should be examined for surface corrosion and free movement, and a test drive should include several firm brake applications from moderate speed to confirm smooth deceleration without judder or pulling to either side, which would indicate warped discs or seized caliper slides. The exhaust system, particularly the diesel particulate filter, should be evaluated for warning lights on the dashboard and any signs of excessive smoke during extended running, as infrequent use of diesel engines commonly leads to blocked DPFs that subsequently require forced regeneration or replacement. The remainder of the pre-purchase evaluation should concentrate on time-based servicing items that are not necessarily reflected in the MOT record. Brake fluid is hygroscopic and degrades on a calendar basis, typically requiring replacement every two years regardless of mileage, and the cooling system coolant along with the diesel engine oil should be verified as within service intervals according to the manufacturer's time-based schedule rather than purely by odometer reading. The 12-volt battery should be load-tested, as prolonged standing periods are a leading cause of premature battery failure in commercial vehicles. Underbonnet checks for fluid leaks around the power steering system, which is a known area of concern on the Master platform, and inspection of the suspension bushes and coil springs for any signs of corrosion or cracking should also be undertaken. A thorough service history verification is strongly recommended to confirm that time-sensitive maintenance has been performed, ensuring the vehicle is fit for continued reliable service.
