2016 Citroen C4 1.6L Diesel · 123 BOM

A history of drivetrain and braking component wear defines this Citroen C4, though the recent testing trend shows an absence of recorded defects. While the most recent test on 18 February 2026 resulted in a pass with no defects, the previous years show a pattern of mechanical interventions. Specifically, the vehicle has experienced major failures regarding constant velocity boots on both the nearside and offside front drive shafts, alongside recurring advisories for rear brake pad wear and disc corrosion. The record indicates a transition from several years of intermittent component wear and failure to a period of clean results in the last two years. The vehicle has covered 65,450 miles over its ten-year lifespan, which equates to an average annual usage of approximately 6,545 miles. This represents a relatively low annual mileage for a vehicle of this age. Mechanically, this level of usage suggests that while the drivetrain and suspension components may not have been subjected to high-frequency heavy loading, the vehicle has likely spent significant periods stationary or used for short, infrequent trips. Such usage patterns can sometimes contribute to the surface corrosion seen on brake discs or the degradation of rubber components like CV boots, which were flagged in previous inspections. Prospective buyers should pay close attention to the front drivetrain assembly during a test drive. Given the history of split constant velocity boots on both the nearside and offside front outer drive shafts, it is essential to listen for any rhythmic clicking or popping noises when turning the steering wheel at low speeds or while maneuvering. Such sounds can indicate that dirt has ingresssed into the joint following a boot failure, potentially leading to premature joint wear. Additionally, the driver should check for any vibrations through the steering wheel or floorpan during acceleration, which could signal issues with the drive shafts or related mounting components. The braking system also warrants a thorough evaluation. Previous advisories for low rear brake pads and corroding rear discs suggest that the rear braking components have been subject to wear and environmental exposure. During a test drive, the driver should test the brake pedal feel for any sponginess or excessive travel and monitor for any judder or pulsation through the pedal when applying the brakes, particularly when slowing from higher speeds. Any pulling to one side during braking should be investigated, as the history of uneven component wear could indicate binding calipers or uneven pad distribution.
