2019 Citroen Relay 2.0L Diesel · LE19 MZX

The most recent MOT test on the 2019 Citroën C-Connect Relay recorded a passing result on 2026-06-11, yet the advisory items regarding front and rear brake pads wearing thin persist, indicating a consistent trend of brake system degradation over the past three years. While the vehicle has passed subsequent MOTs without major failures, the recurring thin pad advisories suggest that brake wear is a persistent issue, likely linked to either excessive daily mileage or suboptimal braking habits. The failure in 2026-06-06—due to registration plate lamp and side repeater issues—was primarily non-mechanical, but the persistence of brake advisories highlights that the driver may need to address this sooner rather than later, as thin pads can compromise stopping performance and increase the risk of failure between MOTs. The earlier minor power steering pipe failure in 2024-03-21, while not present in the latest test, underscores the need for vigilance over the vehicle’s mechanical integrity, particularly in high-stress areas like the steering system and suspension. The recorded mileage of 133,701 miles for a vehicle aged seven years represents a notably high annual usage rate of approximately 19,100 miles per annum, which is well above the average for its class. Such mileage accumulation over a relatively short period can accelerate wear on consumables like brake pads, tyres, and suspension components, as well as fluid degradation in the braking, cooling, and lubrication systems. The absence of significant mileage gaps suggests the vehicle is in active use, potentially under heavy or frequent driving conditions, which may explain the consistent brake advisories and the snapped power steering pipe. It is also worth noting that high-mileage vehicles often experience more rapid tyre wear patterns, such as uneven tread degradation, which could indicate misalignment, suspension issues, or incorrect tyre pressures. The turbocharged engine may also be subject to increased turbocharger wear or oil consumption if not serviced regularly, given the oil leak advisory from 2025-03-29, though this was deemed not excessive. For a prospective buyer, the most critical areas to inspect are the braking system and suspension, given the recurring thin pad advisories and the potential for further wear. During a test drive, listen for uneven brake pedal response, excessive vibration or shuddering during braking, or signs of brake fluid contamination, which could indicate hydraulic issues or warped discs. Inspect the brake pads and discs for uneven wear, corrosion, or binding calipers, and check for any fluid leaks around the brake master cylinder or caliper components. The suspension should be examined for excessive clunking or rattling, particularly when driving over bumps, which may signal worn suspension bushes, broken coil springs, or damaged control arms. Additionally, verify that the steering system operates smoothly without resistance or play, as the snapped power steering pipe in 2024 suggests a history of steering-related wear or failure. Beyond mechanical checks, focus on the vehicle’s age and mileage to identify potential hidden issues. Given the high recorded mileage, inspect the tyres for sidewall cracking or perishing, which can occur even at moderate speeds over time, and ensure they have sufficient tread depth to meet current legal limits. Check the battery for signs of corrosion around terminals, poor connections, or reduced cold-cranking amps, as older vehicles are more susceptible to battery failure. The engine oil and coolant should be examined for colour, consistency, and any signs of dilution or contamination, as fluid degradation can accelerate component failure. Finally, review the service history for the turbocharged engine, as high-mileage turbo vehicles often require more frequent oil changes and turbocharger maintenance to prevent long-term damage. If the service book is missing or incomplete, consider arranging a pre-purchase inspection by a qualified mechanic to assess the remaining structural integrity, exhaust emissions compliance, and any undetected wear or damage.
