2007 Citroen C4 1.7L Petrol · OV57 LSZ

The most recent MOT test for this Citroën C4 took place on 2025-10-08, where it passed with a single minor defect related to the offside front constant velocity (CV) joint boot deterioration, alongside an advisory for slight play in the offside front anti-roll bar ball joint. While this is a positive outcome, the vehicle’s MOT history reveals a pattern of recurring issues, particularly with the offside front CV joint boot and parking brake efficiency, which both failed as major defects in 2023. The repeated advisories on the offside front anti-roll bar ball joint and CV boot insecurity suggest a persistent mechanical concern that has not been fully resolved, indicating either ongoing wear or a design or installation flaw. The failure to address these recurring problems could point to either inadequate maintenance or underlying structural wear that has not yet progressed to critical failure but warrants close monitoring. The vehicle’s recorded mileage of 94,751 miles over approximately 19 years represents an annual usage rate of around 4,987 miles, which is notably lower than the industry average for a vehicle of this age. Such low mileage often correlates with periods of prolonged inactivity, particularly if the car has been stored for extended periods, which can exacerbate issues like fluid degradation, corrosion, and component stiffness. The absence of rapid mileage accumulation suggests that the vehicle may have been used sparingly, but this also raises concerns about potential standing-related wear, such as brake disc corrosion or binding calipers, as well as the impact of prolonged idling on seals, gaskets, and lubrication systems. The low mileage record alone does not mitigate the need for thorough inspection, especially given the MOT history’s recurring defects. For a prospective buyer, the most critical areas to inspect are the front CV joint boot and anti-roll bar ball joint, as these have been flagged repeatedly. Visually check the CV boot for signs of cracking, bulging, or excessive dirt ingress, which could indicate seal failure or internal component wear. During a test drive, listen for unusual clunking or rattling noises from the front suspension, particularly when transitioning between rough and smooth surfaces, as this may signal loose or worn ball joints or suspension bushings. The offside front CV joint’s failure history suggests that the boot may have already compromised the joint’s integrity, leading to potential joint wear or misalignment. Additionally, verify the parking brake system’s efficiency by engaging it fully and checking for excessive play or binding, which the 2023 MOT failure highlighted as a major concern. Beyond the MOT-recorded issues, given the vehicle’s age and low mileage, it is advisable to perform a comprehensive physical inspection. Examine the tyres for sidewall perishing or cracking, which can occur even with low mileage due to prolonged exposure to the elements. Check the tyre tread depth and look for signs of uneven wear, which may indicate suspension or alignment problems. Inspect the brake discs for corrosion, warping, or binding calipers, as standing vehicles can lead to rust buildup on discs and reduced braking performance. The battery should be tested for voltage and charge capacity, as low usage may result in a weakened or failing 12V battery. Fluid levels, particularly the engine oil, coolant, and brake fluid, should be checked, with a reminder that fluids degrade over time regardless of mileage. If the vehicle has been stored for significant periods, consider a thorough service check, including a timing belt inspection if applicable, and verify that all service records are up to date, particularly for the CV joint boot replacement and parking brake servicing that should have been addressed by now.
