2008 Citroen Relay 2.2L Diesel · AF08 HZX

The most recent DVSA examination on 19 August 2025 resulted in a pass, although the vehicle carried forward five advisory items from the test four days earlier which had initially caused a failure due to insufficient parking brake efficiency. That earlier failure on 15 August 2025 was attributable solely to the parking brake performance falling below the required threshold, while the advisories relating to nearside front tyre wear, nearside front shock absorber oil misting, and front headlamp lens contamination remained consistent across both tests. Looking at the broader history, the 2024 test produced a similar pattern of advisories alongside a failure for ineffective windscreen wipers and incorrect indicator colour, and the 2023 pass recorded a minor exhaust leak and slight wheel bearing noise. Overall the trend suggests a vehicle that is being maintained to a pass standard but is showing a recurring pattern of advisory-level deterioration in consumable and suspension components, with intermittent major defects related to lighting and parking brake function rather than any sustained structural or corrosion-related failure. With recorded mileage of 95,665 over approximately eighteen years, this Relay has averaged around 5,315 miles per year, which is notably low for a commercial-derived vehicle. Such low annual usage often indicates either genuine light duty or extended periods of standing, and both carry mechanical implications that may not be fully reflected in the MOT record. Long periods of inactivity typically accelerate degradation of brakes through disc corrosion and caliper binding, degrade the 12V battery through chronic partial discharge, and promote perishing of rubber components such as tyres, drive belts, and suspension bushes. Where standing is suspected, it is prudent to confirm the mileage against the service book and any digital service records, as significant gaps between recorded readings can reveal whether the odometer has tracked actual use or whether periods of lay-up have been omitted from the record. In terms of buyer guidance, the recurring advisories on the nearside front tyre being worn close to the legal limit warrant close physical inspection of all four tyres for remaining tread depth, even wear patterns, and any signs of sidewall perishing or cracking consistent with age rather than use. The front shock absorber oil misting noted in the most recent test is an early indicator of seal degradation and should be monitored for progression, with symptoms to listen for on a test drive including excessive body roll through corners, prolonged nose-dive under braking, and clonking over uneven surfaces which would suggest the units require replacement. The parking brake efficiency failure is a known concern on commercial vehicles of this age, often linked to rear cable stretch or corrosion within the drum or caliper mechanism, so a firm test on an incline is advisable, alongside checking for handbrake travel and any warning of the mechanism not holding securely. The persistent front headlamp lens haziness, while currently not reducing light output significantly, will continue to deteriorate and may compromise night-time visibility and MOT compliance in future tests. Given the low annual mileage, particular attention should be paid to age-related items that MOT testing does not directly cover. Brake discs that have been subject to prolonged standing may exhibit surface corrosion and lipping that produces judder under braking, while caliper slide pins and pistons can seize, leading to uneven pad wear or a dragging brake feel. The 12V battery should be load-tested regardless of its cranking performance, as a battery that has undergone repeated partial cycling will hold surface charge but fail under sustained load, particularly in colder conditions. Time-based servicing items such as engine coolant, brake fluid, and gearbox or differential oil should be verified against calendar intervals rather than mileage, as these fluids degrade chemically over time and lose protective function independent of use. Finally, the exhaust leak noted in 2023 and the general age of the vehicle make it worthwhile to inspect the full system from manifold to rear silencer for corrosion at joints and mounting rubbers, and to verify that the timing belt replacement interval has been observed in the service history, as neglect of this item on a diesel engine of this vintage carries severe mechanical consequence.
