2016 Citroen C4 1.6L Diesel · DL66 BKK

This Citroen C4 presents a mixed maintenance picture. The most recent test on 9 June 2026 at 76,521 miles resulted in a pass, but only after a failure the previous day at 76,519 miles. That failure flagged worn and pitted rear brake discs on both sides, a nearside rear tyre worn close to the legal limit, and degraded anti-roll bar linkage ball joint dust covers on both front corners. The rapid retest and pass suggest these items were rectified immediately, yet the pattern of recurring advisories and borderline failures points to a vehicle that has been kept running rather than proactively maintained. The mileage progression tells a consistent story. Between the June 2024 pass at 66,084 miles and the June 2025 test at 71,654 miles, the car covered roughly 5,570 miles in twelve months. The following year it added just 4,866 miles by June 2026. This is slightly below the typical annual average for a ten-year-old vehicle, but the accumulation is steady enough to rule out long periods of disuse. No suspicious gaps or sudden jumps appear in the record, which supports genuine rather than clocked mileage. The 2025 failure is the most technically revealing entry. A fractured rear coil spring on both sides, combined with a very low coolant level, indicates the car was driven in a compromised state for some time before that test. Front brake pads were wearing thin and rear brake discs were already pitted and scored, while the front anti-roll bar showed surface corrosion. These are not catastrophic failures, but they suggest deferred servicing rather than regular preventive care. The same rear brake disc wear advisory has appeared in three consecutive tests, including the most recent pass, meaning the underlying braking system has been a persistent weak point. A buyer should focus on the rear suspension and braking components during any in-person inspection. Check the rear coil springs for cracks or sag, and examine the rear brake discs and calipers for uneven wear or binding. The degraded front anti-roll bar linkage dust covers mean those joints should be assessed for play and corrosion ingress. Verify the coolant level and inspect the cooling system for leaks, given the very low level recorded in 2025. The outstanding recall flagged in both June 2026 tests must be confirmed as addressed with Citroen before purchase.
