2013 Citroen C4 1.6L Diesel · ST13 AEN

The Citroën C4’s most recent MOT test on 2025-09-03 at 91,425 miles confirms a stable roadworthiness trend, though the immediate preceding test on 2025-09-02 at 91,391 miles—just three days earlier—was a failure without recorded defects. This suggests either a procedural oversight or a last-minute rectification of a non-recorded issue, as no faults were logged in either test. The pattern of passing and failing tests in consecutive years (2024 and 2025) without defects implies the vehicle has not suffered from persistent mechanical failures, but the lack of recorded issues also means no evidence of proactive maintenance beyond the minimum MOT requirements. Mileage progression shows consistent usage, averaging around 7,000 miles annually, which is typical for a vehicle of this age. The gap between the 2023 and 2024 tests—covering 8,228 miles in 11 months—does not indicate excessive wear, nor does the 1,335-mile interval between the 2025 failure and pass suggest neglect. However, the absence of any advisory notes or defects over the past three years means there is no historical data to confirm whether critical components like suspension bushes, coil springs, or brake calipers have been replaced or inspected beyond the MOT threshold. Given the lack of recorded defects, a buyer should prioritise an independent inspection of high-wear items not typically caught by the MOT. Focus on the suspension—particularly the rear bushes and coil springs—for signs of uneven wear or corrosion, as these are common failure points in this model. The brakes, while not flagged, should be checked for uneven pad thickness or binding calipers, especially if the vehicle has been driven hard or in wet conditions. Structural integrity, particularly around the wheel arches and sills, should also be scrutinised for corrosion, as the C4 is prone to rust in these areas despite passing MOT tests. The absence of emissions-related failures suggests the engine and catalytic converter remain functional, but a smoke test or diagnostic scan would confirm no hidden exhaust or fuel system issues.
