GK03 AEM MOT History
Interpretation generated from the recorded test data above — not an official DVSA statement and not a substitute for an independent inspection.
3 MOT tests are recorded for this 2003 Ford Fiesta (GK03 AEM) between July 2025 and August 2026.
The record contains 2 passes and 1 failure.
The most recent test on 11 August 2026 was a pass, although the earlier record includes 1 failure that buyers may want to investigate.
Across all tests, the most frequently flagged areas are: Lighting (3 issues), Windscreen (2 issues), Brakes (2 issues), Suspension (1 issue). Repeated mentions in one area can indicate an ongoing pattern worth checking in person.
In total 6 advisory notices are recorded. Advisories flag items that passed but may need attention before the next test; they are not evidence of how well the vehicle has been serviced.
Recorded failure items include: “Offside Rear Suspension component mounting prescribed area excessively corroded significantly reducing structural streng”; “Offside Front Outer Drive shaft joint constant velocity boot split or insecure, no longer prevents the ingress of dirt (”; “Offside Headlamp aim too low (4.1.2 (a))”.

Our Verdict
Exercise extreme caution before purchasing this 2003 Ford Fiesta. While the low mileage is appealing, the recent history of structural corrosion and multiple mechanical failures suggests this vehicle requires significant ongoing investment to remain roadworthy.
When inspecting this vehicle, focus heavily on the underside. The MOT history explicitly mentions structural corrosion on the offside rear inner sill, which is a major red flag for a car of this age. You must verify if this was professionally repaired or merely patched, as structural integrity is paramount for safety.
Furthermore, check the service history for evidence of regular oil and filter changes, especially given the diesel engine. Given the history of brake pipe corrosion, ensure that all lines have been properly treated or replaced rather than just cleaned. Do not take the seller's word on repairs; insist on seeing invoices for the work carried out following the 2025 MOT failure.
As a 1.4-litre diesel from 2003, this Fiesta should offer decent fuel economy for its age, provided the engine is running efficiently. However, older diesel engines can be costly to maintain, particularly if components like the turbo or fuel injectors begin to fail.
Insurance for a 2003 model is typically affordable, but you should factor in higher-than-average maintenance costs due to the vehicle's age and the likelihood of recurring corrosion-related repairs. Expect an estimated annual running cost of £1,100-£1,400, accounting for fuel, insurance, tax, and the inevitable garage visits for an older vehicle.
Prioritise a thorough inspection of the vehicle's structural integrity. The inner sills and brake lines have been flagged for corrosion multiple times; use a torch to inspect these areas for flaking metal or poor-quality welding. Check the steering and suspension components, specifically the power steering hoses and the drive shaft gaiters, as these have been noted as failure points in the past.
Additionally, test all electrical functions, including headlamp aim and rear light clusters, as these have caused MOT failures previously. Ensure the tyres are of the correct and matching specification, as incorrect tyre fitment has been an issue for this vehicle in the past.
This 2003 Ford Fiesta Trend is a low-mileage example, having covered only 78,608 miles in over two decades. However, its recent MOT history reveals recurring issues with structural corrosion, particularly around the inner sills and brake lines. The vehicle has a history of significant failure points, indicating that maintenance has been reactive rather than preventative.
The 2003 Ford Fiesta is generally considered a robust platform, but at 22 years old, reliability is heavily dependent on how well the specific vehicle has been protected from rust.

- Leaking Injector Seals (1.4 TDCI)Moderate
The copper base washers on the Delphi common-rail injectors degrade under heat and cylinder combustion pressure, allowing high-pressure exhaust gases and unburnt diesel to blow past. This creates a hard, black carbon residue known as 'black death' around the injector wells in the cylinder head, accompanied by a rhythmic chuffing noise and pungent diesel exhaust fumes in the cabin. If neglected, the carbon glues the injectors solidly into the head, requiring specialist hydraulic extraction pullers or cylinder head removal.
- EAC Fail (Electronic Accelerator Control)Moderate
The electronic drive-by-wire accelerator system triggers an 'EAC Fail' warning message on the instrument cluster LCD, immediately sending the engine into limp-home mode with revs restricted to around 2,000 rpm. The primary cause is terminal fretting or moisture corrosion on the pins of the multi-pin connector at the throttle body or intermediate engine wiring harness, though worn internal throttle potentiometer tracks or accelerator pedal position sensors can also trigger the fault code (P0121/P0221).
- Front Suspension Coil Spring FractureSerious
The front coil springs on the Mk6 Fiesta are notorious for snapping prematurely, often across the lowest coil winding. Road grit, moisture, and road salt collect in the lower spring cup, corroding the protective coating until the spring fractures under pothole or speed cushion impacts. A snapped spring can drop onto the front tyre, gouging the inner sidewall or causing an immediate blowout, making it a critical safety concern and an immediate MOT failure.
