2007 Citroen C4 1.6L Petrol · MK07 AAZ

The 2007 Citroen C4 holds a valid MOT pass from 24 March 2025 at 114,624 miles, yet the maintenance trend is worsening. In the 14 March 2025 test at 114,469 miles the tester failed the car for excessive corrosion to the offside outer sill and seat belt anchorage area, plus a leaking offside front brake pipe; a pass followed ten days later with slight corrosion noted on rear inner sills. This followed a 28 March 2024 failure at 109,321 miles for near-side rear brake binding, axle imbalance, front exhaust flexi leak, worn front suspension arm bush and steering rack play, though same-day repairs earned a pass at 109,322 miles. The shift from a defect-free 27 March 2023 test at 104,443 miles to structural corrosion failure signals advancing decay. Recorded mileages show light use for a 19-year-old vehicle. The odometer stood at 104,443 miles in March 2023, climbed to 109,322 by March 2024, and reached 114,624 by March 2025. That averages roughly 5,000 miles per year, below the 6,033 annual mean implied by total distance. No rapid accumulation or gaps appear in the supplied three-year span, though missing pre-2023 records limit earlier wear judgement. Prior owners fixed mechanical faults swiftly in 2024 but allowed sill corrosion to progress until it breached structural limits in 2025. A buyer must inspect the offside outer sill and seat belt anchorage zone for weld integrity and residual rust, as the March 2025 failure flagged significant strength loss there. Rear inner sills carry advisory corrosion and require underbody scrutiny. Mechanical foci include the nearside front suspension arm bush, steering rack inner joints, and rear brakes that bound and imbalanced in 2024. Verify the offside front brake pipe repair and check the front exhaust flexi gasket for leaks. The discoloured indicators and poor parking brake noted previously point to intermittent basic upkeep rather than thorough care. Structural integrity now outweighs consumable wear as the primary concern. The car demands a ramp inspection targeting sills, brake pipes and suspension bushes before any purchase commitment.
