2010 Citroen C4 1.6L Diesel · SL10 AWX

A pattern of front‑brake wear, binding and progressive suspension‑joint deterioration dominates this C4’s MOT history, with the most recent test on 25 October 2025 recording a pass but flagging worn, pitted front discs, a binding off‑side rear brake and corrosion to the outer front sill. Earlier failures show recurring issues on the nearside front suspension arm ball joint, split CV boots on both front drive‑shaft joints and a missing steering‑rack gaiter, indicating that wear on the steering and driveline components has been a persistent concern rather than an isolated incident. At 123,133 mi the vehicle averages roughly 7,700 mi per year, a mileage rate that sits within normal usage for a sixteen‑year‑old car and does not suggest unusually aggressive driving. The MOT record shows no prolonged gaps in testing, implying the mileage has been accumulated steadily rather than in large, undocumented bursts. Consequently, wear items that are mileage‑dependent—such as brake discs, tyre tread and suspension bushings—are expected to be approaching the latter stages of their service life and should be inspected with that context in mind. When the car is on the road, pay particular attention to any pulsation or judder when applying the front brakes, especially under moderate to heavy braking, as this can signal the pitted discs or the reported brake‑binding condition. Listen for clunks or knocks over bumps, which may reveal the previously failed nearside front suspension arm ball joint or the lifted front wishbone bush; excessive steering wheel play or a vague wandering sensation could indicate lingering play in the track‑rod end or the missing rack gaiter allowing dirt ingress. Inspect the front wheel arches for fresh rust or flaking around the outer sill, and feel for any looseness in the wheel hubs that might be aggravated by the corrosion noted on the outer sill. The electrical and safety items flagged in the MOTs also merit a focused check: verify that both front position lamps illuminate correctly, confirm the nearside front seat‑belt anchorage feels solid under load, and ensure the nearside rear registration‑plate lamp functions. Examine the condition of the CV boots for any fresh oil seepage that would betray the earlier split‑boot failures, and assess the tyre tread depth and uniformity given the recurring “front tyres worn” advisory. Finally, probe the outer sill area for any new holes or rust progression beyond the previously recorded holed section, as advancing corrosion could affect structural integrity if left unchecked.
