2015 Citroen Relay 2.2L Diesel · LJ15 ADZ

The vehicle shows a declining trend in maintenance quality, moving from a period of clean tests between 2018 and 2021 to a series of recurring mechanical and consumable faults. The most recent MOT on 18 March 2026 at 49,799 miles passed, but the tester flagged corroded brake pipes covered in grease from front to rear, alongside sidewall damage to the offside rear tyre. This follows a similar advisory regarding corroded central brake pipes in the March 2025 test at 45,746 miles, suggesting an ongoing issue with brake line degradation or improper cleaning during inspections. The mileage accumulation is notably low for an 11-year-old vehicle, averaging approximately 4,527 miles per year. The records show consistent, incremental growth from 16,905 miles in 2018 to the current 49,799 miles. While low mileage generally implies less drivetrain wear, the history reveals that the vehicle may have suffered from age-related deterioration, such as perished rubber components and corrosion, which often affect vehicles that spend significant time stationary or undergo infrequent use. A prospective buyer must prioritise a thorough inspection of the braking system. The records show a pattern of issues including pitted brake discs in 2023 and 2024, a failed parking brake efficiency test in March 2024, and the recurring corrosion of brake pipes. The presence of grease or other material on the brake lines, as noted in both 2025 and 2026, makes it difficult to assess the true extent of surface corrosion on the metalwork. A physical inspection is required to ensure the brake lines are structurally sound and not merely masked by cleaning agents. The suspension and tyre condition also warrant attention. The March 2024 failure highlighted multiple tyres worn to the legal limit or damaged, and the 2022 test noted a damaged track rod end dust cover. Although these appear to be addressed through periodic replacements, the recurring nature of tyre damage and sidewall issues suggests a need to check the current wheel alignment and the integrity of all rubber bushings and dust covers to prevent further mechanical degradation.
