2021 Citroen Relay 35 HVY L4H3 ENT Bhdi SS 2.2L Diesel · OV71 HDC

Recurring issues with the braking system and lighting alignment define the mechanical history of this Citroen Relay, which passed its most recent MOT on 27 January 2026 following an initial failure due to a faulty dipped beam headlamp. The vehicle demonstrates a pattern of persistent wear on the rear braking components, with advisories for thinning pads and scored discs appearing consistently across the last two annual inspections. While the lighting defects were rectified to secure the pass, the ongoing brake advisories indicate that these consumables are reaching the end of their service life and will require imminent replacement to maintain safe stopping distances. Accumulating 43,563 miles over five years results in an average of approximately 8,700 miles per annum, a figure that is entirely consistent with typical light-to-medium commercial usage. This steady rate of accumulation suggests the vehicle has been in regular operation rather than subjected to long periods of inactivity, which is generally beneficial for the health of the engine and drivetrain. However, given the nature of the Relay as a heavy-duty platform, this mileage profile implies that the chassis and suspension components have been subjected to consistent load-bearing cycles, necessitating a thorough check of the vehicle's structural integrity and load-carrying capacity. When conducting your test drive, prioritize a focused assessment of the rear braking performance. Listen for any grinding or scraping noises during light to moderate braking, which would confirm the physical degradation of the discs noted in the recent test. If the pedal feel is spongy or if the vehicle pulls to one side under heavy braking, this may suggest that the calipers are starting to bind or that the hydraulic system requires attention beyond simple pad and disc replacement. Ensure you also test the handbrake on an incline, as worn rear components can often lead to reduced parking brake efficiency on this specific model. Beyond the braking system, the history of headlamp alignment failures suggests the front end may have been subject to minor impacts or that the headlamp mounting brackets have become loose or fatigued. Verify that the beam pattern is crisp and correctly focused against a flat wall, and inspect the headlamp units for any signs of water ingress or condensation, which can accelerate internal wiring corrosion. Finally, perform a comprehensive check of the suspension bushes and joints while the vehicle is idling; listen for any metallic clunks or rattles when traversing uneven road surfaces, as the L4H3 body configuration places significant leverage on the front suspension architecture during daily operation.
