2021 Knaus Unknown 2.3L Diesel · PX70 DNN

A pattern of intermittent component failures rather than chronic mechanical degradation defines this vehicle's recent MOT history. While the most recent test on 27 January 2026 resulted in a pass with no defects, the record shows a recurring need for remedial work to address specific safety-critical items. The vehicle failed on 20 January 2026 due to a major fault with the supplementary restraint system warning lamp and previously failed in January 2025 because the front windscreen wiper failed to clear the glass effectively. Despite these isolated failures, the overall trend shows a vehicle that maintains its fundamental roadworthiness once specific, non-structural faults are rectified. The recorded mileage of 19,083 miles against a five-year age profile indicates a low-usage pattern, averaging approximately 3,817 miles per year. This level of annual accumulation is significantly below the UK average, suggesting the vehicle has been used primarily for short trips or has spent extended periods stationary. Mechanically, this low mileage implies minimal wear on high-friction components such as the drivetrain, brake discs, and suspension bushings. However, the intermittent failures noted in the MOT history, such as the wiper motor or SRS lamp issues, can sometimes be associated with vehicles that are not driven frequently, as electrical components and moving parts can occasionally suffer from inactivity or moisture ingress. Prospective buyers should pay close attention to the electrical and safety systems following the recent failure regarding the supplementary restraint system. During a test drive, it is essential to ensure that the airbag warning light illuminates upon ignition and then extinguishes as normal once the engine is running, as a persistent lamp indicates an unresolved fault in the SRS circuit. Additionally, the previous failure regarding windscreen wiper effectiveness warrants a thorough check of the wiper motor operation and the condition of the wiper blades themselves. Ensure the wipers clear the entire windscreen area without streaking, skipping, or making unusual grinding noises, which could indicate a failing motor or worn linkage. Given the low mileage and the nature of the recorded defects, the mechanical integrity of the chassis and suspension appears stable, but a physical inspection of the battery terminals and electrical connections is advised to rule out any issues stemming from infrequent use. While no structural corrosion or fluid leaks have been flagged in the DVSA records, the lack of mileage means that consumables like tyres and brake pads should be inspected for age-related perishing or surface corrosion rather than just tread depth or thickness. Listen for any unusual electrical clicking or hesitation during startup to ensure the low-usage profile has not impacted the charging system.
