2008 Citroen C4 1.6L Diesel · KO08 AFN

Recurring steering and drivetrain issues represent the primary mechanical concern for this vehicle, as evidenced by the most recent MOT pass on 06 June 2026. The record shows a persistent advisory regarding play in the offside front steering rack inner joint, a defect that has been present for at least two consecutive testing cycles. This issue was compounded in the latest inspection by a minor defect involving a severely deteriorated offside front outer drive shaft constant velocity boot. While the vehicle has cleared recent tests, the progression from a steering rack advisory to a failing CV boot suggests a worsening condition in the front-end mechanical components. The recorded mileage of 147,637 miles over approximately 18 years equates to an average annual accumulation of roughly 8,202 miles. This usage pattern is consistent with typical long-term road use for a vehicle of this age. From a mechanical standpoint, this level of mileage suggests that components subject to regular wear and tear, such as suspension bushings, steering linkages, and drive shaft components, are reaching the end of their expected service life. The steady mileage accumulation indicates the vehicle has been in regular use rather than sitting stationary for extended periods, which typically helps prevent certain types of degradation but increases the cumulative fatigue on moving parts. Prospective buyers should pay close attention to the steering and front suspension during a test drive to address the documented issues with the steering rack inner joint and the CV boot. Listen for any rhythmic clicking or popping noises when turning the steering wheel at low speeds or while maneuvering, as this is a common symptom of a failing CV joint resulting from a deteriorated boot. Additionally, pay close attention to the steering feel; any wandering, vagueness, or a sensation of the steering pulling to one side could indicate that the play in the steering rack inner joint has progressed. Further inspection should be directed at the lighting and tyre condition, given the history of registration plate lamp failures and previous advisories regarding tyre wear on the edges. While the registration lamp was noted as inoperative in both 2025 and 2026, the recent focus on the offside front drive shaft requires a physical check of the rubber boot for further splits or grease leakage. Ensure that the front-end geometry is correct, as the previous headlamp aim failure in 2025 could be linked to the ongoing steering rack issues if the vehicle's alignment has been compromised by the mechanical play in the steering assembly.
