2006 Citroen C4 1.6L Diesel · YD56 AEW

The roadworthiness of this vehicle is currently questionable due to an expired MOT and a history of reactive rather than proactive maintenance. While the last recorded test in January 2022 at 97,966 miles passed with no defects, the record is now over four years out of date. The historical trend shows a pattern of multiple failures due to avoidable items such as light bulbs, wipers, and tyre condition, suggesting that the previous owner only addressed mechanical issues when forced by a test failure rather than performing routine preventative inspections. The recorded mileage of 97,966 miles is notably low for a twenty-year-old Citroen, averaging fewer than 5,000 miles per year. However, there is a significant gap in usage data between October 2019 and January 2022, where the vehicle covered approximately 16,800 miles over two years. This low-frequency usage often leads to the degradation of rubber-based components and dry-related seals, which is consistent with the recurring reports of cracked axle bushes and perished dust covers found in earlier tests. A buyer must conduct a thorough physical inspection of the steering and suspension assembly, as these have shown persistent weaknesses. The tester previously flagged excessive free play in the steering rack inner tie rods, damaged track rod end ball joints, and worn anti-roll bar joints. Furthermore, the corrosion on the rear coil springs noted in 2019 requires a close look to ensure structural integrity has not progressed beyond surface rust. Given the history of excessive smoke in 2017, the engine's combustion health should also be verified for signs of turbo wear or oil consumption.
