2015 Citroen C4 1.6L Diesel · EN64 VCT

Recurring issues with tyre wear and exhaust components define the mechanical profile of this Citroen C4, with the most recent test on 01 October 2026 showing a pass but introducing a new advisory for an oil leak. The MOT history reveals a pattern of tyre degradation, with multiple advisories for tyres worn close to the legal limit or worn on the edges appearing in 2023, 2025, and again in 2026. This trend, combined with previous failures regarding headlamp aim and windscreen washer functionality, suggests a vehicle that frequently requires attention to consumables and peripheral systems to maintain compliance. The vehicle has covered 112,028 miles over its eleven-year lifespan, averaging approximately 10,184 miles per year. This represents a typical usage pattern for a petrol or diesel hatchback of this age, suggesting consistent road use rather than long periods of inactivity. Mechanically, this level of annual accumulation indicates that components subject to regular friction and thermal cycling, such as the braking system, suspension bushes, and exhaust assembly, are likely to have reached a stage of significant wear. Prospective buyers should pay close attention to the recent advisory regarding an oil leak, which was noted as not being excessive during the October 2026 inspection. During a test drive, it is necessary to monitor for any visible fluid pooling under the engine bay or a distinct smell of burning oil when the engine reaches operating temperature, which could indicate a leaking gasket or seal. Furthermore, the repeated advisories for tyres being worn on the edges suggest potential issues with wheel alignment or suspension geometry. You should listen for uneven road noise at motorway speeds and check for any steering pull or instability when navigating corners. The history also highlights concerns with the exhaust system, specifically an advisory for a flexi pipe in poor condition in 2024 and a defective exhaust mounting in 2023. On a test drive, listen for any unusual vibrations, rattling, or increased engine noise, particularly during acceleration or idling, which may indicate exhaust movement or a failing flexi-joint. Additionally, given the 2022 advisory regarding pitted or scored rear brake discs, it is prudent to check for any pedal judder or grinding noises when applying the brakes to ensure the braking surfaces have been adequately addressed.
