2018 Mercedes-Benz Citan 1.5L Diesel · DF68 NTO

The most recent DVSA MOT test on 2026-04-25 resulted in a clean pass, marking a return to compliance after two consecutive failures in 2024. While the 2023 and 2022 MOT records were also largely free of major defects, the 2024 failures—particularly the critical faults in the supplementary restraint system (SRS) and the offside front position lamp—suggest a period of either unresolved or newly emerging electrical/electronic issues. The vehicle’s return to passing status indicates either corrective action was undertaken or the faults were non-critical in nature, but the pattern warrants cautious attention. The recurring washer liquid deficiency in 2022 and 2023 highlights a potential fluid management oversight, though this was not a roadworthiness concern at the time. The 126,479 recorded miles for a 2018 Mercedes-Benz C-Class represents a high annual usage rate of approximately 15,810 miles per year, which is significantly above the average for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluid degradation. The absence of service records or clear mileage gaps suggests either heavy, frequent use or a lack of routine maintenance, both of which can lead to premature component failure. For example, high-mileage vehicles often exhibit signs of excessive brake pad or rotor wear, suspension bush deterioration, or oil dilution from frequent short trips. Additionally, the electrical system may be subjected to increased stress from rapid acceleration and deceleration, potentially contributing to the SRS and lamp-related failures observed. Given the vehicle’s mileage and recent MOT history, the buyer should prioritise a thorough inspection of the braking system, focusing on brake pad thickness, rotor surface condition, and the absence of warping or scoring. Listen for unusual noises during braking, such as grinding or squeaking, which could indicate worn pads or damaged discs. The suspension should be checked for excessive play or clunking, particularly around the front wheels, which may signal worn control arms, bushings, or springs. Inspect the exhaust system for leaks or disconnections, as high mileage can lead to rusted or damaged components. The SRS warning lamp fault from 2024 suggests a potential issue with the airbag deployment system or its wiring harness; a professional diagnostic scan could confirm whether this is a minor electrical glitch or a more serious problem requiring repair. Beyond mechanical checks, the buyer should examine the vehicle’s tyre condition for signs of uneven wear, which could indicate misalignment or suspension issues, and ensure the tread depth meets legal requirements. Inspect the tyre sidewalls for cracks or perishing, a common issue in older vehicles exposed to UV degradation over time. Given the vehicle’s age and usage, the 12V battery should be tested for charge retention and overall health, as prolonged idling or high mileage can accelerate battery failure. Fluid levels, including coolant, brake fluid, and transmission fluid, should be checked and topped up if necessary, with particular attention to the coolant system for signs of overheating or leaks. Since the washer liquid deficiency was a recurring but non-major issue, ensuring the reservoir is adequately filled and the washer pump functions properly is advisable. Finally, if the vehicle has been in storage for extended periods, check for standing corrosion on the undercarriage, wheel arches, and brake components, as moisture and salt can accelerate rust formation.
