2015 Mercedes-Benz Citan 1.5L Diesel · SC65 CWT

The most recent MOT test on 2026-04-29 resulted in a passing outcome, though it included two persistent advisories: offside rear brake pipe corrosion with grease accumulation and near-side rear shock absorbers showing light oil misting. Despite this, the vehicle’s overall maintenance history over the past year is neither significantly improving nor worsening, as the latest test reflects recurring but non-dangerous issues that have been present in prior examinations. The failure to pass in April 2026 highlighted critical tyre defects—front tyres with exposed cords and tread depths below legal limits—suggesting that while the vehicle has been brought up to roadworthiness, the wear patterns indicate ongoing stress on the tyres and suspension components. The absence of major failures in the latest test suggests that the vehicle is not currently in a state of imminent failure, but the advisories warrant proactive attention to prevent escalation. The vehicle’s recorded mileage of 184,573 miles at 11 years old represents a high annual usage rate of approximately 16,779 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and tyres, as well as fluid degradation over time. The rapid mileage growth could imply either intensive use or prolonged periods of inactivity followed by heavy driving, both of which contribute to accelerated deterioration. The suspension arm pin or bush wear and the exposed brake pads from the 2023 and 2025 failures indicate that the drivetrain and braking systems have been subjected to significant stress, necessitating closer inspection of these critical components. Additionally, the repeated corrosion of the rear brake pipe and oil misting in the shock absorbers suggest that these areas may require more frequent or thorough maintenance to prevent further corrosion or failure. For the prospective buyer, the most pressing concerns stem from the recurring advisories and failures related to the suspension, tyres, and brakes. Begin by inspecting the rear brake pipe for signs of corrosion progression or leaks, as the grease accumulation could indicate underlying brake fluid contamination or seal failure. During a test drive, listen for uneven brake pedal travel, pulsations, or a spongy feel, which may signal warped discs, binding calipers, or internal brake fluid issues. The near-side front suspension arm pin or bush showing excessive wear demands immediate attention, as this could lead to misalignment, steering play, or suspension failure. Check for clunking noises from the front or rear suspension during cornering or over bumps, and verify that the vehicle maintains consistent ride height—any sagging or uneven movement could confirm further wear in the suspension components. In addition to the mechanical concerns, the vehicle’s high mileage and age necessitate a thorough inspection of the tyres for sidewall perishing, cracks, or signs of excessive dry rot, which can compromise structural integrity. Given the repeated tyre failures, replace all tyres to the legal minimum tread depth (1.6mm) and consider upgrading to higher-quality compounds if the vehicle is driven in wet or harsh conditions. Verify the 12V battery health, as prolonged inactivity or high mileage can lead to sulphation or weak terminals, which may cause electrical system failures. Check the brake discs for corrosion, binding calipers, or uneven wear, as the prior brake pad failures suggest potential disc surface damage or warping. Finally, ensure all fluids—brake fluid, coolant, and transmission fluid—are topped up and free from contamination, as fluid degradation over time can exacerbate wear on seals and bearings. If possible, review the service history for any missing or outdated fluid changes, particularly those recommended at 100,000–150,000 miles or every two years, as the vehicle’s age and mileage may have passed these intervals.
