2010 Citroen C4 1.6L Diesel · WM10 YVC

A 2010 Citroen C4 with three consecutive MOT passes presents a fundamentally sound roadworthiness picture, though the emergence of a corrosion advisory on the nearside front coil spring at the December 2024 test introduces a mechanical watchpoint that warrants attention. The advisory was issued under section 5.3.1 (b) (i) of the MOT inspection manual, which signifies a defect that is not yet at the stage of failure but has been identified as something likely to deteriorate. The prior two tests in August 2022 and August 2023 returned completely clean results with no advisories or defects recorded, so the coil spring corrosion represents a relatively new development rather than a chronic, longstanding issue. This is a typical pattern for a vehicle of this age where components gradually succumb to environmental exposure, particularly in regions where road salt is used during winter months. With 116,193 miles recorded against a 2010 manufacture date, the vehicle has accumulated roughly 7,262 miles per year on average, which sits squarely within expected parameters for a car of its vintage and original market positioning. The testing history shows annual MOTs from 2022 through 2024 with no significant gaps, suggesting the vehicle has remained in consistent operational use rather than being laid up for extended periods. This continuity of use is mechanically beneficial because it indicates that seals, gaskets, brake system components, and drivetrain items have been kept in regular working order rather than suffering the drying-out and fluid degradation that affects stationary vehicles. The mileage accumulation rate is moderate enough to suggest mixed usage including motorway and urban driving, which generally promotes healthier component longevity than purely short, cold-start urban runs. For a prospective buyer, the primary inspection focus should centre on the front suspension, particularly the nearside front coil spring that was flagged for corrosion. On a test drive, listen carefully for any metallic knocking or rattling sounds from the nearside front wheel area when traversing speed bumps, potholes, or uneven road surfaces, as a severely corroded spring can fracture and produce audible clonking under load. Visually inspect the spring through the wheel arch or from beneath the vehicle for flaking, deep pitting, or any signs of section loss, and check the corresponding mounting seats at the top and bottom for associated corrosion. It is also worth having the front suspension bushes, top mounts, and the anti-roll bar drop links assessed for play, as components in the same vicinity often deteriorate at a similar rate once corrosion initiates on related parts. Beyond the spring advisory, the overall mechanical condition should be evaluated against the broader expectations for a high-mileage Citroen of this generation. During the test drive, pay attention to any steering vagueness, pulling to one side under braking, or uneven tyre wear patterns which could indicate worn front suspension components or binding brake calipers. Inspect the exhaust system visually for corrosion at the mounting points and rear silencer box, which are common failure areas on older vehicles. Check the engine bay for any oil misting or staining around the cam cover and sump gasket area, and verify that the cooling system shows no signs of leaks at the radiator, expansion tank, or hose connections. A final practical step is to request that the nearside front coil spring be re-examined by a specialist before purchase, as corrosion advisories can progress rapidly between MOT tests and may warrant replacement before the next annual inspection becomes due.
