2007 Ford Fiesta 1.6L Diesel · EN57 AFA

The 1.6 TDCi diesel engine is the most economical Fiesta variant, with real-world fuel economy of around 55–65 mpg possible for mixed driving. As a December 2007 car, it sits in a higher VED bracket than newer equivalents, and diesels registered before the 2017 changes typically pay £165–£210 per year in road tax, depending on exact CO2 figures. Insurance for a 1.6 TDCi Fiesta is usually group 5–7, so premiums should be modest.

Maintenance costs for this generation of Fiesta are reasonable at independent garages, with an annual service in the £150–£220 range and brake/disc work commonly needed by this age. The diesel-specific items — DMF, clutch, EGR valve and turbo — can become expensive once they fail, often £500–£1,200 for clutch or flywheel replacement. Budget for the advisories flagged in the latest MOT as immediate costs.

Estimated annual running cost: £800–£1,100, covering fuel, tax, insurance and routine servicing. This assumes no major mechanical intervention; if the gearbox mount, anti-roll bar link or wheel bearing worsen, add £300–£600 in the short term.

Start with the items flagged in the December 2025 MOT. Jack the car up and check the lower gearbox mount for cracking or separation — a worn mount allows the engine to twist under load. Inspect the offside front anti-roll bar linkage for play in the ball joints, and examine the offside front wheel for cracks around the rim as well as distortion. The noisy offside front wheel bearing should be spin-tested to confirm whether it is merely dry or has actual roughness.

The frayed offside front seatbelt must be inspected visually along its full length; any fraying means the belt must be replaced. The headlamp lens defect has now appeared on two tests (2023 and 2025), suggesting clouding or moisture ingress — check for condensation inside the lamp unit. The rear gearbox mounting flagged in 2024 is a separate component to the front mount and should also be physically examined.

On the 1.6 TDCi specifically, look for diesel-specific weak points: oil leaks from the cam belt area (a known concern on this engine), EGR valve fouling, and turbo actuator wear. Check the clutch for slipping or judder, and feel for any roughness from the dual-mass flywheel. Finally, inspect the underbody and wheel arches for corrosion — 19-year-old Fiestas, particularly diesels that have done many short trips, are prone to rust around the rear axle and sills.
