2016 Citroen Relay 2.2L Diesel · MX66 RWW

This 2016 Citroen Relay presents a notably clean mechanical profile in terms of recorded DVSA test outcomes, with three pass certificates and two failures over the most recent five-test window, none of which carried any advisory notes or defect entries against the vehicle. The pairing of a fail on 24 July 2025 followed immediately by a pass on 25 July 2025, mirrored by an almost identical fail-then-pass sequence at the August 2024 test, suggests a pattern where minor items are being rectified between tests rather than any chronic or structural mechanical deterioration. With no corrosion advisories, no suspension component flags, no brake or exhaust defects recorded across the entire visible history, the vehicle demonstrates a consistent record of roadworthiness compliance. The absence of advisories on a commercial vehicle of this age and type is particularly reassuring, given that Relay chassis of this generation are well known for accumulating advisories around front suspension bushes, rear axle components and underbody corrosion as mileage climbs. At 90,729 recorded miles over a ten-year lifespan, the annual accumulation rate of roughly 9,073 miles per annum is broadly typical for a working van of this class and sits within the expected operational envelope for light commercial use. There are no apparent extended gaps between tests that would indicate long periods off the road with potential consequences for brake disc corrosion, tyre flat-spotting or battery degradation, and the mileage progression between tests appears consistent with steady commercial service rather than any sudden spikes that might indicate towing, heavy load work or a change of use. Mechanically, this usage profile means the drivetrain, clutch and major engine components have been worked regularly rather than subjected to either the shock loading of high-mileage courier work or the detrimental effects of prolonged standing. The relatively moderate mileage does, however, place the vehicle in a zone where timing belt replacement intervals, dual-mass flywheel wear and turbocharger condition on the higher-output variants become increasingly relevant considerations outside the MOT record itself. For a prospective buyer, the absence of recorded advisories does not eliminate the need for a thorough physical inspection, particularly given the known weaknesses of the Relay platform. Particular attention should be paid to the front MacPherson strut top mounts and lower wishbone bushes, which commonly deteriorate with age even when not flagged at test, producing a clonking noise over speed bumps and vague steering feedback. The rear leaf spring eyes and shackle bushes should be examined for cracking and wear, as should the rear anti-roll bar drop links if fitted, with any signs of loose body or knocking under load warranting closer scrutiny. A test drive should include firm brake applications from moderate speed to check for pedal judder indicative of warped front discs, slow-speed manoeuvres with full lock to listen for any grinding or binding from the front calipers, and a stretch of uneven road surface to expose any suspension slack that the stationary MOT test would not detect. Given the clean advisory record, the buyer should still verify several service-driven items that fall outside MOT scope but are critical on a diesel van approaching a decade of service. Confirm the timing belt and water pump replacement history, as the recommended interval on these engines is typically six years or 100,000 miles, meaning this vehicle is due or overdue depending on the documented schedule. Inspect the underside for any oil weeping from the sump, injector lines or turbo seals, as diesel misting can accumulate over time without triggering a test failure. Check the condition of the dual-mass flywheel on manual variants by listening for a rattling noise on deceleration with the clutch depressed, and verify that the EGR valve and diesel particulate filter have no warning lights illuminated, as commercial use with frequent short journeys can accelerate DPF saturation. Finally, examine the sliding side door mechanism, rear door hinges and the integrity of the load floor, as corrosion in these areas is common on working vans and rarely appears in MOT data until it becomes structurally significant.
