2012 Citroen Relay 2.2L Diesel · BT61 AEA

The latest MOT test on the 2012 Citroën C-Series Relay occurred on 23rd July 2026, resulting in a pass with three advisories and one minor defect. While the vehicle has not failed an MOT in the past four years, the recurring advisories—particularly those related to suspension components such as the near-side rear leaf spring anchor pin/bush wear and front track rod end ball joint play—suggest a pattern of wear that may indicate underlying mechanical fatigue or substandard maintenance. The failure in July 2026 for a non-functional horn and rear fog lamp, alongside the previous offside headlamp issue, highlights a concerning trend in lighting system reliability, which could point to wiring, connector, or bulb failures that warrant closer inspection. The presence of multiple advisories on suspension joints and brakes, coupled with the oil leak, underscores the need for proactive servicing to prevent compounding issues such as increased play in steering components or premature bearing failure in the suspension system. The recorded mileage of 198,039 miles for a vehicle aged 14 years represents an annual usage rate of approximately 14,146 miles, which is exceptionally high for its age. Such sustained high mileage accelerates wear on consumables like brake pads, tyres, and suspension components, as well as internal engine and transmission elements. The absence of significant mileage gaps suggests the vehicle has been in regular, heavy use, which may have contributed to the observed wear on components like the rear leaf spring and front Macpherson strut ball joints. Additionally, prolonged periods of high stress on these systems could exacerbate issues such as bush degradation, leading to clunking noises during cornering or uneven ride quality. The oil leak, if left unaddressed, could further degrade engine components over time, potentially causing sludge formation or increased wear on seals and bearings. For a prospective buyer, the Citroën C-Series Relay requires a meticulous inspection to address the recurring mechanical and electrical advisories. Begin by examining the suspension for signs of excessive play in the front Macpherson strut ball joints and rear leaf spring anchor areas, which may manifest as clunking noises when driving over bumps or uneven surfaces. Listen for any unusual suspension clunks or rattles, particularly near the rear axle, and check for uneven tyre wear patterns, which could indicate misalignment or suspension misalignment. Inspect the oil leak at the front of the vehicle, ensuring it is isolated to a specific component such as a valve cover gasket or oil filter housing seal, and confirm it is not a more widespread issue like a failed oil pan gasket. The brake discs show minor wear but are not seriously weakened, yet the advisories suggest potential issues with brake system consistency; test for brake shudder during deceleration or binding calipers by applying the brakes firmly while observing disc warping or uneven wear. In addition to the mechanical checks, verify the electrical system’s reliability by testing all headlamps, fog lamps, and the horn under various driving conditions. Check the registration plate for any signs of further deterioration that could affect legibility, and ensure the windscreen and side windows are intact without cracks or damage that could impair visibility. Given the vehicle’s age and high mileage, focus on the following critical areas: inspect the tyre sidewalls for signs of perishing or cracking, which can indicate age-related degradation despite the current tread depth; test the 12V battery for a full charge and ensure all electrical connections are clean and corrosion-free; and check for any standing corrosion on the chassis or undercarriage, particularly around wheel arches and exhaust components, as prolonged exposure can weaken structural integrity. Finally, consult the service records to confirm that the last oil change and fluid servicing were performed within the recommended intervals, as high-mileage vehicles benefit from calendar-based fluid changes to mitigate internal wear and maintain lubrication efficiency. If service history is incomplete, arrange for a comprehensive fluid top-up and filter replacement, including brake fluid, coolant, and transmission fluid, to address potential calendar-based degradation.
