2016 Citroen C4 1.6L Diesel · MF16 NVW

The 1.6-litre BlueHDi diesel engine in the C4 typically returns around 55-65 mpg on a combined cycle, though real-world figures of 50-60 mpg are more common. Road tax for a 2016 diesel C4 in this specification falls into a higher VED band, likely £150-£165 per year given post-April 2016 registrations use the revised bands, though if it costs over £40,000 new it would be in the premium tax bracket.

Insurance for the C4 sits in group 15-22 depending on trim, so expect premiums of £450-£650 annually for an average driver. Maintenance costs are moderate, with annual servicing around £200-£300 for a diesel, though timing belt replacement can cost £400-£600 when due. Common wear items include brake discs and pads, clutches on manuals, and DPF-related repairs if the car has been used for short journeys.

Estimated annual running costs including fuel, tax, insurance, and maintenance are likely £1,200-£1,500 per year assuming moderate mileage of 7,000-8,000 miles.

The MOT record shows a clean test pass at 99,865 miles with no advisories or failures logged, which is a positive indicator for the car's roadworthiness as recorded at that test. The single failure in September 2025 had no defects recorded — this should prompt questions about whether the failure was administrative (e.g., emissions readiness, dashboard warning lights) or a deeper mechanical issue that was rectified. Request sight of the failure documentation.

For the 2016 C4 diesel specifically, inspect the DPF for soot build-up by checking the oil level (rapid oil consumption suggests DPF issues), the AdBlue system for leaks or warning messages, and the EGR valve for carbon build-up common on high-mileage diesels. Examine the suspension for wear — the front wishbones and rear beam bushes are known weak points on the C4 and can produce MOT failures for play in components.

On a test drive, check for any smoke from the exhaust (particularly under acceleration), ensure the clutch is not slipping given the mileage, and listen for any timing chain rattle on cold start. Verify all warning lights extinguish promptly and that there are no stored fault codes that might indicate intermittent issues not yet at failure threshold.
