2004 Ford Fiesta 1.2L Petrol · ET53 ACF

The most recent MOT, carried out on 16 March 2026, was passed but returned several advisories – notably corrosion of both rear coil springs, corrosion of the rear brake pipe and a smeary rear wiper. Over the last three years the vehicle has moved from a failure in March 2023 (excessively corroded front brake pipe and tyre wear) to a series of passes with recurring corrosion advisories on the suspension, brake pipe and sub‑frames. The trend is therefore relatively stable: the major fault that caused the 2023 failure appears to have been remedied, yet the same categories of corrosion continue to appear each year, indicating a persistent but not escalating problem. At 57 132 miles on a 2004 Fiesta the average annual mileage works out at roughly 2 600 mi, well below the typical 8‑10 000 mi per year for a vehicle of this age. Such low utilisation often points to long periods of inactivity or very light use, which can be as consequential as high mileage. Age‑related wear will dominate the condition of rubber components, seals and metal surfaces, while the limited wear on moving parts may have allowed moisture to settle, encouraging the corrosion now evident on the suspension and brake pipe. Potential rapid mileage spikes are not evident, but any future increase in use should be matched by a proactive service schedule. A prospective buyer should give particular attention to the rear coil springs and associated suspension bushings. Inspect the springs for pitting, flaking or loss of material and check for any sagging of the rear axle; a noticeable dip in ride height or a metallic clunk when traversing bumps can signal spring fatigue or compromised mounting points. Examine the brake pipe – both front and rear – for surface rust, perforations or signs of fluid leakage; the brake pedal should feel firm with no sponginess, and the vehicle should stop in a straight line without pulling to one side. The rear sub‑frame should be inspected for surface rust and any signs of weakening, especially around welds; excessive flex or squeaking when applying power or braking may indicate that corrosion has begun to affect structural rigidity. Given the car’s age and low mileage, broader time‑based checks are essential. Verify that all four tyres have sufficient tread depth and inspect the sidewalls for cracking, dry rot or bulging, as ageing can degrade rubber even on low‑use tyres. Test the 12‑volt battery for charge holding capacity and look for any signs of sulphation, particularly if the vehicle has spent long periods stationary. Drain and replace brake fluid if it has not been serviced within the last two years, as moisture absorption can reduce boiling point. Finally, confirm that the engine oil, coolant and transmission fluids have been refreshed according to a calendar schedule rather than mileage, and that the service book contains appropriate stamps for any major services or component replacements. These inspections will give a clear picture of whether the Fiesta remains mechanically sound or will soon require remedial work.
