2016 Citroen Relay 2.2L Diesel · YX16 AEU

Electrical system irregularities and recurring lighting defects define the mechanical history of this Citroen Relay, with multiple failures recorded for inoperative indicator, position, and marker lamps. The most recent test on 22 July 2025 resulted in a pass, but it highlighted a pattern of electrical and component wear, including a defective side repeater lens and severely deteriorated inner drive shaft constant velocity boots on both sides. This follows a significant failure in July 2025 where the engine Malfunction Indicator Lamp was found to be inoperative, a major defect that had also appeared in a failure in June 2024. The vehicle has covered 84,051 miles over approximately ten years, representing an average annual usage of roughly 8,405 miles. This mileage is consistent with typical light-to-medium commercial use for a vehicle of this age. While the mileage is not excessive, the recorded history shows that components such as drive shaft boots and braking surfaces are beginning to reach the end of their service life, which is common for a vehicle operating in this mileage bracket. Prospective buyers should pay close attention to the drivetrain and braking components flagged in the latest advisory. The deterioration of both front inner drive shaft CV boots can lead to grease loss and subsequent joint failure; during a test drive, listen for clicking or popping noises when turning the steering wheel at low speeds or feel for vibrations through the floorboard under acceleration. Additionally, the advisory regarding thinning front brake pads on both sides necessitates an immediate inspection of the remaining pad thickness and disc surface condition to ensure there is no significant scoring or uneven wear. The recurring issues with lighting and the previous major failure regarding the engine MIL suggest that a thorough electrical system check is required. Inspect all external light clusters, including marker lamps and indicators, to ensure there is no intermittent failure or moisture ingress. Furthermore, the advisory for a nail in the nearside rear tyre indicates that tyre condition and puncture repairs should be closely examined. On the test drive, check for any steering pull or uneven tyre wear that might indicate underlying suspension geometry issues, particularly given the previous minor defect involving the offside front track rod end dust cover.
