2006 Citroen Relay 2.2L Diesel · LB55 SWX

The most recent MOT test for the 2006 Citroën Relay on 2026-07-29 resulted in a passing grade, though it was accompanied by several persistent advisories that indicate ongoing issues requiring attention. While the vehicle has not failed an MOT in the past year, the pattern of recurring defects—particularly in the front brakes, suspension components, and fluid-related concerns—suggests a trend of wear and potential underlying mechanical degradation rather than a stable or improving condition. The front brakes advisory, noting imbalanced requirements, is particularly critical as it points to a need for brake adjustment or repair to ensure consistent stopping performance and prevent uneven wear or failure. The oil leak and corroded power steering components further underscore the need for proactive maintenance to avoid escalating issues that could compromise road safety or lead to costly repairs. The vehicle’s recorded mileage of 132,514 miles over approximately 20 years represents a moderate annual usage rate of around 6,626 miles per year, which is typical for a car of this age and class. However, the history of frequent MOT failures and advisories, especially in high-wear areas like the suspension and drivetrain, suggests that the vehicle has likely undergone significant stress over time. The presence of structural advisories from earlier tests—such as deformations in the vehicle’s sills and arches—indicates that the frame may already be compromised, potentially affecting ride quality, handling, and even long-term durability. While lower mileage could imply lighter use or periods of inactivity, the combination of high mileage and repeated mechanical failures suggests that the vehicle has been subjected to substantial driving conditions, accelerating wear on critical components. For a prospective buyer, the most pressing concerns stem from the front brake system, which shows signs of imbalance and potential uneven wear. On a test drive, listen for uneven brake pedal travel or a spongy or pulsating feel, which could indicate warped discs or binding calipers. Inspect the front brakes for signs of excessive heat discoloration on the discs or uneven tread wear on the pads, as these are clear indicators of imbalance or impending failure. The nearside front drive shaft joint and its constant velocity boot have failed multiple times, with the latest test revealing a split or insecure boot that no longer prevents dirt ingress. This is a major failure that must be addressed immediately, as it risks lubricant loss, increased noise, and potential drivetrain damage. During inspection, check for excessive whine or clunking noises from the front axle area, especially when accelerating or turning, which are symptomatic of a failing joint. Additionally, the suspension components, particularly the rear shock absorbers, have shown significant fluid leaks and deterioration. The latest MOT noted a serious leak from the offside rear shock absorber, which is a critical failure that can lead to poor ride quality, instability, and even loss of control. On a test drive, look for a loss of damping—where the vehicle feels bouncy or unstable over bumps—and listen for a hollow or rattling noise from the rear suspension. The front suspension ball joint was also found to be excessively worn in the previous MOT, which could result in clunking noises when driving over rough roads or a reduced ability to absorb road imperfections. Inspect the suspension for excessive play or binding in the joints, and check for uneven tyre wear patterns that may indicate misalignment caused by suspension issues. The oil leaks noted in previous tests should also be investigated, as they may stem from worn seals or gaskets in the engine bay or transmission area. Finally, given the vehicle’s age and the history of battery insecurity, verify the 12V battery’s health by checking for corrosion on terminals, ensuring it holds a charge when the ignition is off, and confirming that all electrical systems, including the headlamps and washer, function correctly. For a car of this age, a thorough inspection of the tyre sidewalls for signs of perishing or cracking is essential, as these can indicate underlying structural weaknesses or prolonged exposure to UV degradation. Additionally, consider checking the fluid levels—oil, coolant, and brake fluid—against manufacturer recommendations, as fluid degradation over time can lead to performance issues or failure.
