2022 Citroen Relay 35 L3H2 Eprise Bhdi S/S 2.2L Diesel · LB22 UUY

The most recent DVSA MOT test for the 2022 Citroën Relay 35 L3H2 EPRISE BHDI S/S was conducted on 2025-06-19, resulting in a failure due to an engine malfunction indicated by the Malfunction Indicator Light (MIL) being inoperative or displaying an incorrect code (8.2.2.2 (g)). This is a critical failure, as the MIL’s functionality is essential for driver awareness of potential engine issues, and its absence or incorrect display can mask serious problems such as catalytic converter failure, oxygen sensor defects, or fuel system malfunctions. The prior MOT test on the same date in 2025-06-19 was passed with no recorded defects, suggesting that the engine issue was either newly developed or not previously detected during the initial inspection. This inconsistency indicates a potential deterioration in engine performance or a failure to properly diagnose the underlying cause during the previous test, warranting immediate attention to prevent further damage or safety risks. The recorded mileage of 60,469 miles for a vehicle aged four years represents a high annual usage rate of approximately 15,117 miles per annum. While this is not uncommon for some vehicles, particularly those in commercial or high-demand use, such mileage accelerates wear on critical components. The suspension system, brakes, and drivetrain components—such as the constant velocity joints, universal joints, and exhaust manifolds—are particularly susceptible to increased stress and potential failure due to the higher frequency of operation and thermal cycling. Additionally, higher mileage can lead to more rapid degradation of consumables like brake pads, engine oil, and coolant, as well as potential issues with tyre wear patterns, which may indicate misalignment or suspension wear. The absence of significant mileage gaps suggests consistent use, which could also contribute to issues like standing corrosion on components such as the brake calipers or exhaust system if the vehicle has been left stationary for prolonged periods. Given the recent MOT failure related to the engine MIL and the high recorded mileage, the prospective buyer must prioritise a thorough mechanical inspection of the Citroën Relay 35. The first step is to confirm the exact cause of the MIL malfunction through a professional diagnostic scan, as this may reveal whether the issue stems from a faulty oxygen sensor, a failing catalytic converter, or a problem with the engine control unit (ECU). During this inspection, the buyer should also verify the engine’s compression, fuel pressure, and ignition timing to rule out more severe internal engine issues such as valve wear, piston ring failure, or head gasket problems. On a test drive, listen for abnormal noises such as knocking, ticking, or misfires, which could indicate underlying mechanical or electrical faults. Additionally, check for any fluid leaks around the engine bay, particularly from the oil pan, coolant reservoir, or transmission fluid housing, as these could signify failing seals or gaskets. Beyond the immediate engine concerns, the buyer should conduct a comprehensive inspection of the vehicle’s suspension, brakes, and tyres, given the high mileage. Inspect the suspension for signs of wear, such as cracked or swollen coil springs, worn suspension bushes, or binding control arms, which can lead to uneven tyre wear or steering instability. Test the brakes by applying the pedal firmly and listening for grinding, squeaking, or pulsation, which may indicate worn brake pads, warped discs, or binding calipers. Visually inspect the brake discs for corrosion, scoring, or uneven thickness, and check the tyre tread depth and sidewall condition for signs of perishing or excessive wear. Given the vehicle’s age and usage, it is also advisable to verify the condition of the 12V battery, as high mileage can accelerate its degradation, and to check the fluid levels in the cooling system, transmission, and differential, ensuring they are topped up and free from contaminants. If the vehicle has been stationary for extended periods, inspect the exhaust system for rust or corrosion, particularly around the catalytic converter and tailpipes, as standing can exacerbate these issues. Finally, review the service history to confirm that the vehicle has undergone the recommended maintenance intervals, including oil changes, timing belt replacement (if applicable), and fluid servicing, to mitigate further wear and extend the vehicle’s longevity.
