2017 Citroen Relay 2.0L Diesel · RY17 MDJ

A recent failure regarding parking brake efficiency marks the most significant mechanical issue in an otherwise clean MOT history, with the vehicle passing its latest inspection on 16 January 2026 without further defects. This failure in November 2025 indicates a specific deficiency in the handbrake system's ability to hold the vehicle stationary, which was rectified to achieve the subsequent pass. While the absence of recorded advisories in the most recent test suggests the immediate issue was addressed, the sudden emergence of a major parking brake failure is the primary technical point of interest for this vehicle. The recorded mileage of 62,137 miles over a nine-year period reflects an average annual usage of approximately 6,904 miles. This rate of accumulation is relatively low for a commercial vehicle like a Citroen Relay, suggesting it has not been subjected to the high-intensity, high-mileage cycles typical of long-distance courier or heavy haulage work. Mechanically, this lower mileage profile generally implies less cumulative wear on heavy-duty components such as the drivetrain, suspension linkages, and engine internals, though it does not account for the potential effects of long periods of inactivity or intermittent use. Prospective buyers should pay close attention to the braking system during a test drive to ensure the November 2025 failure was fully resolved. Beyond the parking brake, a thorough check of the service brake performance is necessary, specifically looking for any pedal judder or uneven pulling under braking, which could indicate issues with discs or calipers. Given the commercial nature of the vehicle, it is also prudent to inspect the underside for any signs of fluid leaks or excessive corrosion on the subframe and brake pipes, even though no such defects were formally recorded in the recent DVSA history. During the road test, listen for any unusual knocking or clunking sounds from the suspension when driving over uneven surfaces, as this would indicate wear in the bushes or coil springs. While the low mileage suggests less mechanical fatigue, the specific failure of the parking brake mechanism warrants a physical inspection of the rear brake components to ensure there is no binding or excessive play in the mechanism. Any hesitation in the handbrake's engagement or a lack of tension should be treated as a reason for further professional investigation.
