2009 Citroen C1 1.0L Petrol · LL09 XTM

The latest MOT test result for the 2009 Citroën C1 shows it passed on 2025-11-01, but the vehicle’s maintenance history reveals a pattern of recurring issues that warrant cautious consideration. While the tests of 2024 and 2023 were clean, the 2022 MOT recorded a severe failure for the offside front drive shaft constant velocity (CV) boot split, and the 2023 test identified both this boot and the rear CV boot as severely deteriorated. The 2025 test noted minor wear on the rear axle swivel pins and bushes, suggesting ongoing mechanical stress in the differential and suspension linkage, which could indicate progressive wear if not addressed. These advisories and failures point to a maintenance trend that has not fully resolved, with critical drivetrain components—particularly the CV joints and their boots—requiring urgent attention to prevent further damage, such as bearing failure, misalignment, or catastrophic drivetrain failure. The vehicle’s recorded mileage of 148,132 miles over approximately 17 years represents an average annual usage of around 8,714 miles, which is relatively modest for a car of this age and size. Such mileage suggests either light or intermittent use, potentially with extended periods of standing, which can accelerate wear in components like brakes, suspension, and fluids that degrade over time rather than mileage. However, the presence of a failed CV boot at 148,132 miles indicates that the vehicle has already been subjected to significant mechanical stress, particularly in the drivetrain. If the previous owner did not promptly replace the CV boots, the remaining life of these components is likely limited, and further deterioration could lead to costly repairs or even a complete drivetrain failure. Given the MOT history, the buyer should prioritise a thorough inspection of the drivetrain and suspension systems. On a test drive, listen for unusual noises from the front axle, particularly clunking or grinding sounds that could indicate CV joint failure, misalignment, or worn differential components. Check for excessive play or binding in the steering wheel, which may signal suspension bush wear or misaligned wheels. Inspect the CV boots visually for any signs of cracking, bulging, or fluid leakage, and verify that the boots are properly sealed. The rear axle swivel pins and bushes, noted as worn in the 2025 MOT, should also be examined for excessive movement or corrosion, which could lead to steering instability or suspension failure. Additionally, the corroded brake pipe on the offside rear should be checked for leaks or structural integrity, as corrosion can compromise the pipe’s strength and lead to brake fluid loss. Beyond the mechanical checks, the buyer should conduct a comprehensive physical inspection of the vehicle’s condition. Given the age and mileage, the tyres should be thoroughly examined for sidewall cracking or perishing, which can occur even with low mileage if the rubber has degraded from prolonged exposure to the elements. The 12-volt battery should be tested for charge retention and overall health, as older vehicles are more prone to electrical issues from standing or infrequent use. The vehicle’s fluids—particularly the engine oil, brake fluid, and coolant—should be checked for contamination or degradation, as these can deteriorate over time regardless of mileage. A review of any service records or maintenance logs would be beneficial to confirm whether the CV boots were replaced or if other critical services, such as the timing belt or suspension components, have been addressed. Finally, the buyer should consider a professional inspection by a qualified mechanic to assess the condition of the drivetrain components, suspension, and braking system, with a particular focus on the CV joints and rear axle, as these areas have shown recurring issues.
