CITROEN C42008 · 2.0L DIESEL

The Citroen C4 presents a stable, broadly improving maintenance trend heading into its most recent test. In the September 2025 pass at 75,364 miles, the tester flagged only two minor advisories: a slight corrosion to the offside rear brake hose ferrule and a rear brake disc noted as worn, pitted or scored but not seriously weakened. These are low-severity observations, and the car has not failed an MOT since July 2024. The record suggests a vehicle that is fundamentally sound, with no recurring safety-critical failures. Mileage accumulation is low for an 18-year-old hatchback, averaging roughly 4,187 miles per year. The record shows a gap of approximately 5,174 miles between the July 2023 test at 67,821 miles and the July 2024 test at 72,993 miles, then just 2,367 miles over the following fourteen months to September 2025. That tapering pace could indicate lighter recent use or periods of inactivity. Sparse but consistent annual testing is a positive sign, and the mileage progression does not suggest clocking. A buyer should focus on the braking system during any in-person inspection. The offside rear brake hose ferrule corrosion appeared in both the July 2023 failure and the September 2025 pass, indicating a slow-developing issue that has been tolerated rather than rectified. Combined with the flagged rear brake disc condition, the rear braking circuit deserves a thorough check for caliper binding, hose deterioration, and disc thickness. The repeated tyre tread advisories in 2023 and 2024, both on the nearside and offside, point to uneven wear patterns. Suspension bushes, tracking, and wheel alignment should be inspected to rule out the underlying geometry issues that cause such uneven tyre wear. Given the low annual mileage, also assess the condition of rubber components like perishable hoses and door seals, which age regardless of use.
