2021 Dethleffs Trend 2.3L Diesel · LP21 BDO

The Dethleffs Trend presents an unusual and concerning MOT history, with the most recent tests in April 2025—just over a year ago—showing a repeated pattern of pass/fail outcomes at identical mileages (14,975 and 13,491 miles). Neither test recorded any defects, which suggests the vehicle was either rejected for administrative reasons (e.g., missing documentation, expired tax) or, more likely, failed due to a persistent but undocumented mechanical issue. The lack of recorded faults does not equate to a clean bill of health, however, as the repeated failures imply either a deliberate avoidance of addressing underlying problems or a tester’s refusal to overlook something critical. Given the absence of advisories or defects in the official record, the vehicle’s roadworthiness appears stable on paper , but this contradicts the practical implication of two consecutive rejections at the same mileage—raising immediate red flags about transparency or prior neglect. The vehicle’s mileage of 14,975 miles over five years—roughly 3,000 miles annually—is exceptionally low for its age, particularly for a luxury vehicle that typically sees higher usage. The gap between the 2024 and 2025 tests (just over a year) aligns with the MOT retest interval, yet the identical mileage figures on both occasions (14,975 and 13,491) suggest the car may have sat unused for extended periods, possibly stored rather than driven. Such low mileage reduces wear on consumables like tyres and brakes, but it also means critical components—such as suspension fluids, seals, and battery health—may have degraded due to inactivity. The lack of mileage progression between tests further implies either a deliberate suppression of usage or, more troublingly, a failure to log accurate odometer readings. For a prospective buyer, the absence of recorded defects in the MOT history is misleading; the repeated failures demand a thorough pre-purchase inspection. Priority should be given to verifying the structural integrity of the chassis, particularly around suspension mounts, coil springs, and anti-roll bar bushes, as these are prone to corrosion or fatigue even with low mileage. The braking system—including caliper operation, disc thickness, and pad condition—should be scrutinised, as binding or uneven wear often goes unnoticed without dynamic testing. Additionally, the vehicle’s electrical systems, including the battery, starter motor, and lighting circuits, may have suffered from prolonged disuse, leading to hidden faults. Given the MOT’s silence on defects despite two rejections, a full diagnostic check—preferably by an independent specialist familiar with Dethleffs’ unique engineering—is essential before committing to a purchase. The lack of documented issues does not absolve the vehicle of potential hidden risks.
