2021 Citroen Relay 35 HVY L4H2 ENT Bhdi SS 2.2L Diesel · LA21 KXT

The Citroën Relay’s most recent MOT, conducted on 6 June 2025 at 64,435 miles, confirms it passed without any defects, indicating a clean roadworthiness record for the past 12 months. The preceding test on 21 May 2024 at 60,532 miles also showed no issues, suggesting a stable maintenance pattern with no recurring mechanical failures. While the absence of advisories or defects is reassuring, the lack of service history beyond MOTs means critical intervals for diesel particulate filters, turbocharger health, or suspension servicing cannot be verified. The vehicle’s compliance with emissions and structural checks in both tests implies no immediate red flags, but the high mileage accumulation demands closer scrutiny of wear items. The recorded mileage of 64,435 miles over five years—approximately 12,887 miles annually—is unusually high for a vehicle of this age, particularly given its light commercial use. This rate suggests either consistent heavy usage or prolonged periods of inactivity followed by rapid mileage spikes, both of which can accelerate wear on drivetrain components, suspension, and braking systems. The gap between tests (around 11 months) is standard, but the absence of any advisories or defects in either test implies either diligent maintenance or that wear has not yet reached MOT-reportable thresholds. However, the lack of intermediate servicing records raises questions about whether more intensive upkeep—such as turbocharger servicing or differential fluid changes—has been neglected. Given the clean MOT history, a buyer should prioritise a thorough inspection of high-mileage wear items, starting with the diesel particulate filter (DPF), which may require cleaning or replacement given the mileage. The turbocharger, often a critical component in diesel engines at this mileage, should be checked for oil leaks, excessive carbon buildup, or unusual noise during acceleration. Suspension components—particularly the rear coil springs, bushes, and shock absorbers—are likely candidates for degradation, as are the rear brake calipers and discs, which the MOT tester did not flag but could exhibit binding or uneven wear. Structural corrosion, particularly around the wheel arches, sills, and underbody, should be inspected for signs of rust penetration that could compromise structural integrity. Finally, the exhaust system’s integrity should be verified, as diesel vehicles are prone to catalytic converter or muffler failures at this mileage.
