2015 Renault Master 2.3L Diesel · KJ09 FUN

A 2021 stability and braking warning lamp episode, followed by a cluster of lighting, body and glass failures in late 2022, define the mechanical character of this Renault Master before the test record settles into a cleaner run of passes through 2023, 2024 and the most recent examination on 19 December 2025, which was recorded with no defects. The 2021 failure is particularly significant: simultaneous illumination of the ESC, ABS and engine management warning lamps, together with headlamp aim defects on both sides, points to an underlying electrical or sensor fault rather than isolated bulb issues, and a buyer should treat that entry as the single most important item in the file. The 2022 failure is more superficial, involving a damaged door mirror indicator with jagged edges, a broken offside front side repeater, insufficient washer fluid and a windscreen chip encroaching on the driver's view, all of which were evidently remedied within three days when the vehicle was presented again on 22 December 2022 and passed. The subsequent tests show only advisories and minor items, but the cumulative picture is one of a vehicle that has had two distinct adverse episodes in five years rather than a continuous pattern of decline. Recorded mileage of 120,532 miles over an 11-year life equates to an average of roughly 10,950 miles per year, which sits comfortably within expected commercial use for a Master of this vintage. There are no extended gaps in the MOT record, so the vehicle does not appear to have been declared off the road for any prolonged period, and the annual accumulation between tests is broadly consistent with steady working mileage rather than a sudden long-distance tour or extended lay-up. Mechanically, this kind of usage is consistent with moderate wear on the typical heavy-van consumables, brake friction material, clutches and front suspension components, but it does not in itself flag particular concern beyond the items already recorded. The absence of a very long gap is also helpful, because Master vans left standing for many months frequently develop brake caliper seizure, underbody corrosion and 12V battery degradation that then surface in later tests. The most recent advisory, recorded on 10 December 2024, flagged the front inner brake pads as wearing thin, and given the working mileage on this vehicle those pads should now be assumed to have been replaced or to be approaching replacement again. On a test drive, listen for any grinding or squeal from the front calipers on light application, check for pull to one side under braking, and feel for a soft or excessively long pedal travel, any of which would suggest the pads were left to go on too long or that the caliper sliders have seized, a common issue on high-mileage Masters. The earlier tyre advisories on both rear tyres in late 2020 and the offside rear pair in late 2022 indicate a pattern of edge wear rather than even shoulder-to-shoulder wear, which on a rear-driven, heavily loaded van often points to tracking misalignment, worn rear leaf spring bushes or inconsistent loading; inspect the nearside and offside rear tread carefully and look for feathering across the tread blocks. The windscreen damage recorded as a minor in 2023 should also be inspected, as the 2022 episode shows that chips on this vehicle have previously progressed to the point of obstructing the driver's view. Finally, the 2021 MOT failure deserves targeted verification before purchase. Ask specifically whether fault codes were retrieved from the ABS, ESC and engine management systems at the time, what repair was carried out, and whether any of the warning lamps have reappeared since, because ABS and ESC module faults on the Master can be intermittent and may not be picked up on a single short drive. Check that both headlamps are set at the correct height, as the 2021 test found both sides too high, which on this model can indicate failed automatic levelling motors or simply displaced lamps after a front-end knock. Carry out a slow-speed walkaround checking all side repeaters, mirror indicators and washer jets, since the 2022 failure involved multiple missing or damaged items, and verify that the windscreen is free of any chip sitting within the driver's swept area. A pre-purchase diagnostic read of the ABS and ESC modules, a brake fluid renewal given the working mileage, and a thorough inspection of the rear leaf spring bushes and front lower suspension arms would be proportionate precautions on a Master of this age and distance.
