2015 Citroen Relay 2.2L Diesel · BK15 DBO

The Citroën Relay’s most recent MOT test on 2025-12-10 passed without defects, though it follows a failed attempt just three weeks prior on 2025-11-27. This pattern of back-to-back tests suggests either a rushed last-minute inspection or an owner attempting to meet a deadline, rather than a vehicle with a deteriorating mechanical condition. The previous clean passes in 2024 and 2023 indicate no recurring faults were formally recorded, but the lack of defects does not guarantee all high-mileage components remain serviceable. The 2025 tests occurred just 12 months apart, which is within the standard 12-month MOT cycle, though the rapid succession hints at potential pre-test servicing or a vehicle kept in regular use despite its age. The Relay’s recorded mileage of 135,941 miles—approximately 12,358 miles per year—is unusually high for a vehicle of this age, suggesting either intensive use or prolonged periods of neglect. The gap between the 2023 and 2024 tests spans 12 months with no intermediate records, meaning no MOT failures or advisories were logged in that period. The most recent mileage reading of 135,941 miles was recorded at the 2025-12-10 test, implying the vehicle has likely accumulated another 5,000–6,000 miles since then. For a car of this age and mileage, this rate of travel will accelerate wear on suspension bushes, coil springs, and brake components, particularly if the vehicle has not undergone recent servicing beyond MOT requirements. Given the high mileage and the absence of recorded defects, a buyer should prioritise an independent inspection of the suspension geometry, particularly the rear trailing arms and subframe mounts, as these are common failure points on high-mileage Citroën models. The brakes, while not formally failed, should be assessed for uneven pad thickness, glazed discs, or binding calipers—especially if the vehicle has been driven hard. Corrosion checks are essential, particularly around the wheel arches, sills, and subframe, as rust can compromise structural integrity. The exhaust system should be examined for leaks or excessive sagging, as catalytic converter failures are not uncommon in this model at this mileage. Finally, the condition of the tyres—both tread depth and lateral wear—will indicate whether the vehicle has been maintained properly, as failing twice on tyre tread suggests basic upkeep may have been overlooked.
