2016 Citroen C4 1.6L Diesel · PL65 ETA

The most recent MOT test on the 2016 Citroën C4 occurred on 2025-01-22, where the vehicle passed with a single advisory regarding the rear brake pads showing significant wear, classified as 1.1.13 (a) (ii). While this latest result is positive, the broader MOT history reveals a pattern of recurring brake-related advisories and one critical failure. The front brake disc failure in 2024-01-17 was particularly concerning, marked as a "Dangerous" condition under 1.1.14 (a) (ii), indicating that the disc was so severely weakened it posed a serious risk to braking performance. This failure, combined with multiple advisories on brake pad wear and rear disc scoring, suggests that the braking system has undergone considerable stress over time, likely due to either aggressive driving, under-maintenance, or cumulative wear from high mileage. The advisories from previous years—such as the front disc being "worn, pitted, or scored" but not yet critically weakened—highlight a trend where components are nearing or exceeding their serviceable limits, warranting immediate attention to prevent further deterioration. The vehicle’s recorded mileage of 122,132 miles at the time of assessment represents a high annual usage rate of approximately 12,213 miles per year, which is notably elevated for a ten-year-old car. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluid degradation and tyre degradation patterns. The absence of significant mileage gaps in the MOT history suggests that the vehicle has been in active use, potentially with higher-than-average driving demands, which could explain the accelerated wear observed in the braking system. Additionally, high mileage often correlates with increased exposure to environmental factors like road debris, moisture, and temperature fluctuations, all of which can exacerbate corrosion and mechanical fatigue in components like brake discs, suspension bushes, and exhaust systems. Without further context on operational conditions—such as frequent stop-and-go traffic, off-road use, or prolonged periods of standing—the exact causes of the wear cannot be pinpointed, but the pattern strongly indicates that the vehicle has been subjected to demanding conditions. For the prospective buyer, the most urgent concern is the braking system, given the critical failure and recurring advisories. Immediate inspection should focus on the front and rear brake discs, pads, and calipers for signs of glazing, warping, or excessive thickness loss. On a test drive, listen for unusual noises such as squeaking or grinding from the front brakes, which could indicate pad-to-disc contact or caliper binding. Check for a firm, even pedal travel without excessive sponginess or vibration, and ensure no brake fluid leaks are present under the vehicle. The front brake disc failure in 2024 suggests that the discs may have already been compromised, and further deterioration could lead to reduced braking efficiency or even failure under load. The buyer should also verify that all brake hoses and lines are free of cracks or bulges, as fluid leaks can lead to hydraulic failure. Beyond brakes, the high mileage and recurring advisories imply that the suspension and drivetrain may also require closer scrutiny, particularly for signs of excessive play in joints, bushings, or worn bushings, which can manifest as clunking noises over bumps or uneven tyre wear patterns. In terms of practical checks, given the vehicle’s age and mileage, the buyer should conduct a thorough inspection of the tyres for sidewall cracking or perishing, which can occur even with low tread depth if the rubber has degraded from prolonged exposure to the elements. The tyre pressure monitoring system (TPMS) fault from the 2018 MOT suggests that the system may not be functioning correctly, so manual checks of tyre pressures against the manufacturer’s specifications should be performed regularly. The battery should be tested for voltage output and overall health, as older vehicles with high mileage are more prone to electrical issues due to corrosion in terminals or failing starter motors. Additionally, the fluid levels—particularly brake fluid, coolant, and transmission fluid—should be checked and topped up if necessary, with a reminder that fluids degrade over time, even when not used. For calendar-based servicing, the buyer should confirm that the last oil change was performed within the recommended interval, typically every 12,000 to 15,000 miles or annually, whichever comes first, given the vehicle’s age. Finally, the minor registration plate lamp and mirror damage noted in 2018 are cosmetic and do not affect roadworthiness but should be addressed for legal compliance and aesthetic reasons. If the buyer is concerned about the brake system’s condition, a professional inspection by a qualified mechanic is strongly recommended to assess the extent of disc and pad wear, caliper function, and overall braking performance before proceeding with purchase.
