2023 Dacia Duster Comfort LPG TCE 4X2 1.0L Gas bi-fuel · WU73 NDK

The latest DVSA MOT test for the 2023 Dacia Duster Comfort LPG recorded a failure on 2026-07-21 due to a major defect: the windscreen washer system was non-functional, classified as category 3.5(a). This marks a single instance of failure within the past year, with the preceding MOT test on the same date passing without any recorded defects. While the failure is notable, it does not indicate a deteriorating maintenance trend; rather, it suggests a specific component failure that has not been addressed prior to this test. The vehicle’s overall roadworthiness has not been compromised by this defect, as the washer system’s absence does not affect the vehicle’s safety or operational integrity in a critical manner. The fact that the vehicle passed the same test date in the prior year implies that the issue may be intermittent or related to a specific fault that was not present earlier, warranting immediate attention to prevent recurrence. The recorded mileage of 33,412 miles for a vehicle aged three years represents a reasonable annual usage rate of approximately 11,137 miles per annum, which is consistent with typical driving patterns for this model and age group. Such mileage accumulation is generally indicative of moderate to regular use, though it does not necessarily imply excessive wear on all components. The absence of significant mileage gaps suggests the vehicle has been in active service, which can lead to more consistent but not necessarily accelerated wear on consumables like brake pads, tyres, and fluids. However, the LPG fuel system, while robust, may still experience minor condensation or condensation-related corrosion if the vehicle has been left stationary for extended periods, particularly in damp or cold conditions. It is also worth noting that the LPG tank’s pressure relief system and associated components could be subject to wear over time, especially if the vehicle has been driven frequently under varying temperatures. For the prospective buyer, the most critical immediate action is to address the windscreen washer failure, as this is a major defect that must be rectified to comply with roadworthiness standards. The washer system’s non-functionality could be due to a faulty pump, a disconnected hose, or a malfunctioning relay, and a thorough inspection of the electrical connections and fluid reservoir should be undertaken. During a test drive, listen for any unusual noises emanating from the washer motor or check visually for fluid leaks around the washer pump. If the issue persists after repair, consider having the system tested under load to ensure full functionality. Beyond this, given the vehicle’s age and mileage, the buyer should prioritise a comprehensive inspection of the suspension and steering components. Look for signs of uneven tyre wear, which could indicate misalignment or suspension bush wear, and listen for clunking noises when driving over bumps or at speed, as these may signal worn suspension bushes or damaged coil springs. Additionally, check the brake system for signs of binding calipers, corrosion on brake discs, or excessive brake fluid degradation, especially if the vehicle has been left stationary for prolonged periods. In terms of long-term maintenance, the buyer should verify the service history for fluid changes, particularly the engine oil, transmission fluid, and LPG system fluids, which should be replaced according to the manufacturer’s recommendations—typically every 15,000 to 20,000 miles or annually, whichever comes first. Given the vehicle’s age, inspect the tyre tread depth and sidewall condition for signs of perishing or cracking, which can compromise structural integrity and safety. The LPG tank should also be checked for any signs of corrosion or leaks, particularly around the seams and connections, as LPG systems are prone to condensation-related issues. Finally, assess the 12V battery health, as older vehicles may experience reduced capacity or corrosion in terminals if not maintained properly. A simple test drive with the headlights and windscreen wipers engaged can help determine if the battery is holding a charge adequately. If the vehicle has been used in cold climates, check for any signs of water ingress into the LPG system, which could lead to ice blockages or system malfunctions. Overall, while the MOT history is not indicative of widespread issues, the buyer should proceed with a thorough mechanical inspection to ensure all components are in safe and functional condition.
