2017 Citroen Relay 2.0L Diesel · YG67 AAJ

The December 2023 test at 83,173 miles passed with no defects, indicating the vehicle currently meets roadworthiness standards; however, the preceding December 2023 test at 83,113 miles recorded multiple failures, showing a recent improvement after remedial work. The trend is therefore improving, with the most recent result being stable. The vehicle has accumulated 83,173 miles over roughly nine years, averaging 9,241 miles per year, which is typical; however, the interval from the January 2023 test (71,812 miles) to the December 2023 test (83,113 miles) added 11,301 miles in 11 months, a rate of about 12,300 miles per year, suggesting periods of intensified use. Earlier gaps, such as the 18,257-mile increase between September 2020 and January 2022, further indicate variable usage and possible extended idle periods. Recurring faults and inspection points: The repeated parking brake efficiency failures and near‑side headlamp and brake lag issues point to potential wear in the parking brake mechanism, brake pads or discs, and suspension components such as bushes and coil springs. Persistent tyre wear close to the legal limit, observed in 2022 and 2023, warrants close examination of tyre tread depth and wheel alignment. Additionally, the earlier engine MIL inoperative warning suggests checking the diesel injection system and associated sensors. Structural integrity should be assessed for corrosion, especially around the chassis rails and wheel arches, given the vehicle’s age and periods of low mileage.
