2021 Citroen C4 GR Stourer Shine Bhdi SS A 1.5L Diesel · EP21 GYU

The 2021 Citroën C4 Grand Tourer’s latest MOT test on 2026-07-01 resulted in a clean pass, indicating no functional failures or critical defects. This follows a consistent maintenance history with all previous MOTs (from 2024 to 2026) passing without major issues, suggesting a stable mechanical condition. The absence of recurring failures or repeated advisories over the past two years points to either effective upkeep or a vehicle that has not encountered significant wear-related problems beyond routine wear items. However, the presence of two tyre-related advisories—one from 2025 and another from 2026—indicates that the near-side front outer tyre has experienced some degree of sidewall deterioration or damage, which may warrant closer attention in the near term. The recorded mileage of 28,707 miles for a vehicle aged five years represents a relatively low annual usage rate of approximately 5,741 miles per year. Such a low mileage profile is uncommon for a car of this age, particularly one that appears to have been in use, and may reflect periods of prolonged inactivity or light operational use. While lower mileage typically suggests reduced wear on consumables like brakes, suspension components, and drivetrain elements, it also raises concerns about potential standing corrosion, particularly on the near-side front tyre and adjacent structural areas. Extended periods of static storage can accelerate corrosion on metal components, especially in coastal or damp environments, and may have contributed to the observed tyre sidewall issues. Additionally, fluids such as brake fluid and coolant can degrade over time even without use, necessitating checks to ensure they remain within specification. For a prospective buyer, the most critical areas of inspection should focus on the near-side front tyre and its immediate surroundings. The sidewall cracking or perishing noted in the 2026 MOT advisory suggests that the tyre may have been subjected to prolonged exposure to environmental elements, leading to reduced tread depth and potential structural compromise. On a test drive, listen for any unusual tyre noise or vibrations, and visually inspect the tyre for signs of uneven wear or bulges. The near-side front wheel assembly, including the brake disc and caliper, should also be checked for signs of corrosion or binding, as standing conditions can cause rust to form on these components, particularly on the near-side. Inspect the brake discs for uneven wear, grooves, or corrosion, and ensure the calipers move smoothly without resistance when the brakes are applied. If the vehicle has been stationary for extended periods, the near-side suspension bushes and coil springs may also require attention, as they can degrade over time due to lack of movement. Beyond the tyre and brake systems, the vehicle’s age and low mileage profile make it prudent to conduct a broader inspection of time-sensitive components. Check the tyre sidewall for any signs of cracking, perishing, or dry rot, which can compromise safety and lead to sudden failure. Verify the condition of the 12-volt battery, as prolonged inactivity can cause internal deterioration or terminal corrosion. Inspect the battery terminals and cables for cleanliness and secure connections, and consider testing the battery’s charge capacity if possible. Additionally, since the vehicle has not undergone a full service within the last 12 months, it is advisable to verify the presence of service book stamps for critical intervals such as oil change, filter replacement, and fluid top-ups. Pay particular attention to the brake fluid, which should be replaced every two years or 60,000 miles, whichever comes first, as it can absorb moisture and degrade over time. Lastly, check the exhaust emissions system for any signs of corrosion or leaks, as standing conditions can accelerate rusting in the catalytic converter and exhaust manifold. A thorough visual inspection of the undercarriage, including the exhaust and suspension components, will help identify any hidden issues that may have developed due to prolonged inactivity.
