2009 Citroen C4 1.6L Diesel · YP58 VRT

The most recent MOT, carried out on 8 February 2024, was passed but returned several advisories covering the front suspension arm bush, the near‑side front tyre, both front inner brake pads and the front brake disc. Compared with the preceding three‑year record – which included three outright failures for major safety items such as a fractured rear coil spring, rear‑brake imbalance and multiple lighting and washer failures – the trend is clearly moving in a more positive direction. The vehicle has managed to clear the test after addressing the most serious faults, yet the persistence of front‑end wear items indicates that the maintenance regime is still only partially effective and that further attention is required to prevent a regression to failure status. At 106,153 miles the car has accumulated an average of roughly 6,200 miles per year over its 17‑year life, a usage pattern that sits comfortably within typical UK figures. This suggests the car has not been subjected to extreme high‑speed or heavy‑load duty, but the relatively modest annual mileage also raises the possibility of extended periods of inactivity. Prolonged standing can accelerate rubber hardening, battery sulphation and corrosion of suspension bushings, all of which are reflected in the current advisory list. For a prospective buyer the front suspension arm bush should be inspected for excessive play or a knocking sensation when the steering wheel is turned at low speed; any clunk or looseness could indicate that the bush is nearing the end of its service life and will need replacement. The front tyres, both flagged as close to the legal tread limit and worn on the edge, should be examined for uneven wear patterns, sidewall cracking and any signs of perishing – a tyre that has been stored for long periods can develop dry rot even if the tread depth appears acceptable. The brake system warrants particular scrutiny: thin inner pads on both sides and a front disc that is already worn will soon require a full pad set and possibly disc resurfacing or replacement, while the historic rear‑brake imbalance suggests the rear calipers or shoes may be unevenly worn or the hydraulic balance valve may be out of adjustment. A test‑drive should reveal any pulsation through the pedal, pulling to one side or a high‑pitched squeal when braking, all of which would confirm that rear‑brake service is overdue. Additionally, the previous failure of the off‑side rear coil spring means the rear suspension should be checked for any sag, uneven ride height or audible creaking, as a broken spring can compromise handling and load‑carrying capacity. Given the car’s age, time‑based items should be addressed regardless of mileage. The 12‑volt battery is likely approaching the end of its useful life and should be load‑tested; a weak battery can cause intermittent electrical faults such as the engine MIL light that was recorded as inoperative. All exterior lighting – especially the position lamp and registration plate lamp that have previously failed – must be verified for correct operation and proper aim. The washer system jets should be cleared and the pump tested to ensure adequate fluid delivery, as misaligned jets were noted in the latest advisory. Finally, a thorough visual inspection for corrosion on the chassis, especially around the rear suspension mounts and wheel arches, and a check that all fluid reservoirs (engine oil, brake fluid, coolant and power‑steering fluid) have been refreshed within the recommended intervals will help to avoid hidden failures that often emerge in vehicles of this vintage.
