2020 Renault Master 2.3L Diesel · DX20 AYC

The Renault Master’s most recent MOT history reveals a concerning pattern of repeated failures despite no recorded defects on either test date. The vehicle failed twice in quick succession—first on 2026-03-12 and then again on 2026-03-17—both at the same mileage of 154,713, suggesting a systemic issue either overlooked by the tester or a deliberate attempt to bypass proper inspection. The lack of specific fault codes in these failures is particularly troubling, as it implies either a technical error in testing or a recurring problem that evades standard MOT checks. The previous clean passes in August 2024 and June 2023 do not mitigate this risk, as the failures cluster within the last year, indicating a worsening trend rather than an isolated incident. The mileage progression of 154,713 miles at the latest tests—an average of over 25,000 miles annually—signals aggressive usage for a vehicle of this age. Between the 2023 and 2024 tests, the odometer jumped from 143,193 to 154,129 in just under a year, a rate that exceeds typical commercial or private usage patterns. This rapid accumulation raises immediate concerns about accelerated wear on high-stress components such as suspension bushes, coil springs, and drivetrain bearings. The absence of any advisory notes or partial failures in prior tests further suggests that minor issues may have been ignored or that the vehicle was operated despite known wear, which is a red flag for structural integrity. Given the repeated failures without clear fault identification, a buyer should prioritise a thorough inspection of the suspension system, particularly the rear axle and steering linkages, where binding or excessive play often goes undetected in standard MOTs. The brakes, though not explicitly flagged, warrant scrutiny for uneven wear or binding calipers, especially if the vehicle was driven aggressively. Corrosion around wheel arches, subframes, and exhaust mounts should also be examined, as high mileage and potential neglect could have accelerated rust-related failures. The lack of recorded defects in prior passes does not preclude hidden damage, so a professional pre-purchase inspection with a focus on wear-and-tear patterns is essential. The recent failures alone justify caution, as they imply either a lack of proper maintenance or a vehicle pushed beyond its expected service life.
