2007 Citroen Relay 2.2L Diesel · KV57 AHN

Persistent issues with the exhaust system, braking efficiency, and suspension components define the mechanical profile of this Citroen Relay, with the most recent test on 08 July 2026 showing a trend of accumulating advisories. While the vehicle has passed its last several inspections, the frequency of warnings regarding the exhaust box being holed and mounts perishing, alongside recurring low offside parking brake effort, indicates a pattern of wear that is not being fully rectified between tests. The mechanical state appears to be transitioning from isolated component wear to more systemic issues, particularly concerning the exhaust integrity and the front-end suspension geometry. The recorded mileage of 164,380 miles over approximately 19 years equates to an average annual usage of roughly 8,652 miles. This represents a moderate usage pattern for a commercial vehicle of this age, suggesting it has not been subjected to extreme high-frequency heavy haulage, nor has it sat idle for extended periods. However, the cumulative mileage is sufficient to have caused the documented degradation in rubber components, such as the leaf spring bushes and exhaust mounts, and the gradual development of wheel bearing noise and oil seepage noted in the historical records. A prospective buyer should pay close attention to the underside of the vehicle, specifically the exhaust system and its mounting points, as the 2026 advisory for a holed exhaust box and perished mounts suggests an imminent need for replacement to avoid noise or emissions issues. The recurring advisory for low offside parking brake effort since 2024 requires investigation; during a test drive, the parking brake should be applied on an incline to check for holding strength, and the pedal should be monitored for any unusual travel or lack of resistance. The driver should also listen for any rhythmic grinding or humming from the front wheels, which would correlate with the historical reports of noisy wheel bearings and the recent advisory regarding a rough nearside front hub. Suspension and drivetrain integrity should also be a primary focus during a physical inspection. The recent advisory for wear on the nearside front lower suspension ball joint, combined with the 2021 failure regarding worn rear leaf spring anchor pins and bushes, indicates that the chassis and suspension linkages are subject to significant stress. On the road, the driver should look for any knocking or clunking sounds when traversing uneven surfaces or turning the steering wheel, and check for any pulling to one side which could indicate uneven wear or component play. Finally, the long-term presence of oil leaks, though described as not excessive in previous years, should be monitored for any increase in volume or fresh staining around the engine area.
