2007 Citroen C4 2.0L Diesel · KV57 AHC

A significant mechanical disruption occurred in mid-2025, characterized by multiple dangerous and major defects that contrast with a previously consistent record of clean passes. While the vehicle secured a pass on 21 July 2026 with no defects recorded, the 2025 inspection revealed critical failures involving seriously weakened nearside and offside front brake discs, a missing nearside front drive shaft constant velocity boot, and a dangerous defect regarding the rear inner seat belt. This period of failure was followed by an advisory for an offside rear tyre worn on the edge in July 2025, though the subsequent 2026 test indicates these specific issues have been addressed. The vehicle has covered 100,423 miles over its nineteen-year lifespan, representing an average annual accumulation of approximately 5,285 miles. This is a relatively low mileage profile for a 2007 model, which can imply less frequent wear on drivetrain components and suspension linkages compared to higher-mileage vehicles. However, such low annual usage can also result in components being subjected to longer periods of inactivity, which may affect the condition of rubber seals and various moving parts. Prospective buyers should pay close attention to the braking system and front-end drivetrain following the serious failures recorded in 2025. During a test drive, it is essential to check for any signs of pedal judder or vibration under braking, which could indicate uneven disc wear or surface irregularities, and to listen for any clicking or popping noises when turning the steering wheel at low speeds, which might suggest issues with the drive shaft joints. The previous advisory regarding the offside rear tyre being worn on the edge also warrants a visual inspection of the rear suspension geometry to ensure there is no excessive camber or alignment pull that could cause premature tyre wear. Furthermore, the safety-critical failure of the rear inner seat belt should be verified as fully rectified. A physical inspection of the seat belt anchoring points and the webbing should be conducted to ensure the mechanism is secure and does not show signs of fraying or detachment. Given the history of brake disc deterioration and drive shaft boot issues, a thorough examination of the front wheel arches for any signs of grease leakage or debris from a split boot is also advised to confirm the integrity of the CV joints.
