2007 Citroen C4 1.6L Petrol · GF07 SOU

A recurring pattern of braking system issues and suspension component wear defines the mechanical profile of this Citroen C4, with the most recent test on 6 March 2026 showing a pass following a major failure for a binding nearside rear service brake. The testing history indicates a trend of significant component degradation, particularly regarding the parking brake efficiency and anti-roll bar ball joints which failed in February 2025. While the vehicle has moved past the immediate braking failure, the presence of a new advisory for a minor exhaust gas leak suggests that while the primary safety defects are being addressed, secondary emissions and exhaust integrity issues are emerging. The vehicle has covered 140,895 miles over its nineteen-year lifespan, averaging approximately 7,416 miles per year. This represents a typical usage pattern for a vehicle of this age, suggesting consistent rather than excessive road use. Mechanically, this level of annual accumulation means that components subject to fatigue, such as suspension bushings, ball joints, and braking hardware, are likely to be approaching the end of their service life, which is reflected in the recorded failures of the anti-roll bar linkages and the parking brake mechanism. Prospective buyers should pay close attention to the braking system during a test drive, specifically looking for any uneven pulling when braking or a sensation of the car dragging to one side, which could indicate the nearside rear caliper is still prone to binding. The advisory regarding the parking brake efficiency in 2025 and the insecure rear brake cable should prompt a thorough check of the handbrake's holding strength on an incline. Additionally, the recent advisory for a minor exhaust leak warrants a close inspection of the exhaust manifold and pipework for signs of corrosion or soot staining, which may manifest as an audible increase in engine noise or a slight vibration through the floorpan. The suspension history, specifically the previous major failures of the nearside and offside front anti-roll bar ball joints, necessitates a careful evaluation of the steering and ride quality. During a test drive, listen for any rhythmic knocking, clunking, or rattling sounds when traversing uneven surfaces or turning the steering wheel at low speeds, as these are classic symptoms of worn ball joints or deteriorated suspension bushes. The deterioration of the front registration plate and the previous minor windscreen damage are cosmetic and visibility-related items, but the mechanical focus must remain on the exhaust, braking, and front-end suspension components flagged in the DVSA records.
