2018 Mercedes-Benz Citan 109 CDI Blueefficiency 1.5L Heavy oil · RF68 FNU

The most recent MOT test on the 2018 Mercedes-Benz Citan, conducted on 2026-07-22, resulted in a clean pass with no defects or advisories recorded. This follows a pattern of consistent MOT outcomes from 2023 through 2025, with the only notable deviations occurring in 2022, where the vehicle failed due to tyre defects and thin brake pads, and received multiple advisories about brake pad wear and wheel distortion. The absence of failures or critical issues in the last four years suggests a stable maintenance history, though the recurring advisories from 2022 indicate ongoing wear that should not be ignored. The vehicle’s performance during this latest test appears to be reliable, but the long-term implications of the 2022 advisories—particularly the brake pad wear and wheel distortion—must be monitored closely to prevent escalation into more serious mechanical or safety concerns. The recorded mileage of 109,161 miles for an eight-year-old vehicle represents a high annual usage rate of approximately 13,645 miles per year, which is significantly above the average for its age. Such mileage accumulation typically accelerates wear on critical components such as brake systems, suspension elements, tyres, and drivetrain elements, particularly if the vehicle has been subjected to frequent stop-and-go traffic or heavy loads. The advisories from 2022 regarding brake pad thinning and wheel distortion align with the expected wear patterns associated with high mileage, suggesting that the driver has likely driven the vehicle under conditions that have contributed to these issues. Additionally, the presence of a rear tyre nail and slight tyre cracking or perishing further supports the notion of aggressive or prolonged use, which can lead to premature tyre degradation and potential road hazards. For a prospective buyer, the most critical areas to inspect are the brake system and wheels, given the recurring advisories from 2022. Begin by visually inspecting the front and rear brake pads for even wear—uneven wear could indicate misalignment or binding calipers, which may cause shuddering or pulsating during braking. Listen for any unusual noises, such as grinding or squeaking, which could signal pad wear or warping. On the wheels, check for distortion or uneven wear patterns, and ensure there is no binding when the brakes are applied. The near-side front wheel distortion may cause misalignment, leading to steering pull or uneven tyre wear, so verify that the steering angle and wheel alignment are correct. Additionally, inspect the rear tyres for the nail and any signs of cracking or perishing, as these can compromise grip and safety, particularly in wet conditions. If the tyre nail is removed and the remaining tread depth is above the legal minimum, proceed cautiously, as the crack or perishing may indicate underlying tyre degradation. In terms of broader maintenance checks, given the vehicle’s age and high mileage, focus on the following time-sensitive and wear-related items. The brake fluid should be checked for contamination or moisture buildup, as high mileage and frequent braking can accelerate fluid degradation. A visual inspection of the brake fluid reservoir for discolouration or sediment is advisable, and if necessary, a flush should be performed. The suspension components, including coil springs, shock absorbers, and suspension bushes, should be examined for signs of wear or damage, such as excessive play, clunking noises during cornering, or uneven suspension travel. The tyre sidewall should be inspected for any signs of cracking or perishing, which can occur over time even with low mileage, especially if the vehicle has been stored in a dry environment. Finally, check the 12V battery and associated electrical systems, as prolonged idling or high mileage can lead to battery drain or corrosion buildup. A load test should be performed to ensure the battery holds a charge, and the battery terminals should be cleaned of corrosion to prevent further electrical issues. Since the vehicle has not been serviced in recent years, verify the service book for any scheduled fluid changes, such as coolant, oil, and transmission fluid, which should be replaced according to the manufacturer’s recommendations—typically every 60,000 to 100,000 miles or every two years, whichever comes first. If the service history is incomplete, consider arranging a comprehensive service to address any potential fluid degradation or wear-related issues.
