2011 Citroen C4 1.6L Diesel · MT11 XMJ

The most recent MOT on 20 January 2026 was passed, with only a minor fault for the nearside rear registration‑plate lamp being inoperative. This follows a period of significant non‑compliance in 2023‑2025, where headlamp aim and lamp‑type mismatches, a dangerous front‑brake disc condition and under‑depth rear tyres caused failures. Since the 2024 and 2025 headlamp faults have been rectified and the 2026 test shows no major safety items, the maintenance trajectory appears to be stabilising, although the persistence of minor lighting and rear‑shock‑bush advisories suggests that some components are still being monitored rather than fully resolved. At 93,131 mi the car averages roughly 6,200 mi per year, which is modest for a fifteen‑year‑old vehicle. The relatively low annual mileage points to periods of light use or prolonged storage, both of which can be as consequential as high mileage. Light use reduces wear on consumables such as brake pads and tyres, but it also encourages rubber hardening, battery sulphation and corrosion of suspension bushings that are not regularly exercised. There is no evidence of any sudden mileage spikes that would indicate aggressive driving or heavy load use. The buyer should concentrate on the items that have repeatedly appeared in the MOT record. Verify that the front‑headlamp units now match the type specified by the manufacturer and that both aim and colour temperature are correct; an incorrect aim will manifest as uneven illumination on the road and may cause glare to on‑coming traffic. Inspect the front brake disc for any scoring, cracking or excessive run‑out – a dangerous disc was recorded in 2023, so a replacement may have been carried out, but visual inspection and a test‑drive brake feel check (absence of pulsation or shudder) are essential. Examine the rear tyre tread depth and sidewall condition; the 2023 failure for sub‑1.6 mm tread suggests the tyres may have been replaced, but confirm that the current set meets the legal minimum and shows no age‑related cracking. The rear shock absorber bushes were flagged as slightly worn in both 2024 and 2026; listen for clunking or excessive bounce over bumps and check for uneven tyre wear that could indicate deteriorating bushings or worn coil‑spring mounts. Given the vehicle’s age and modest mileage, a thorough age‑related inspection is prudent. Check all tyre sidewalls for dry‑rot or cracking, as rubber can perish after six years regardless of use. Examine the battery for signs of sulphation and test its cranking voltage; a battery that has sat idle for long periods often requires replacement. Inspect the coolant, brake fluid and power‑steering fluid for colour and level – fluids degrade over time and should be flushed at least every two to three years. Look for corrosion on chassis mounting points, especially around the rear suspension and steering rack, and ensure that any rust is surface‑level and not affecting structural integrity. Finally, confirm that the service book contains stamps for regular oil changes, timing‑belt or chain service (if applicable), and that any major component replacements (brake discs, shocks, tyres) are documented with dates and mileage.
