2006 Ford Fiesta 1.2L Petrol · YR06 CFV

A pattern of progressive structural and underbody corrosion defines the mechanical history of this 2006 Ford Fiesta, with the most recent test on 4 December 2025 recording advisories for both sides of the rear integral body structure, the rear subframe mounting prescribed area, and a minor exhaust gas leak from the central rear section. While the vehicle ultimately passed on that date, the same test began as a failure due to a serious fluid leak from the nearside rear shock absorber, indicating the dampers are no longer holding their hydraulic charge. The corrosion picture has developed steadily: by 2022 the nearside and offside rear suspension component attachment brackets were already recorded as seriously weakened, and the subframe and body structure advisories have carried forward into subsequent tests, suggesting these areas are slowly deteriorating rather than remaining static. The fuel system has also drawn repeated attention, with a major rear fuel pipe leak recorded as a failure in November 2022 and a corroded, slightly leaking fuel pipe advisory in November 2024, pointing to ongoing degradation of the underfloor fuel lines. A clean pass in November 2021 with no recorded defects shows the structural and corrosion concerns only became apparent from the 2022 test onwards, meaning the trend over the last third of the vehicle's life has been one of accumulating advisories rather than stable roadworthiness. Against an age of roughly twenty years, the recorded mileage of 75,763 miles equates to an average accumulation of around 3,788 miles per year, which is notably low for the vehicle's age and consistent with light rather than heavy service use. There are no significant gaps in the MOT testing record, with annual tests documented from 2021 through 2025, so the low mileage reflects steady but limited running rather than a prolonged period off the road. Mechanically, low annual mileage on a twenty-year-old car reduces wear on high-mileage consumables such as brake discs, clutches, and drivetrain internals, but it can also mean extended standing periods, which tend to accelerate moisture-related deterioration of brake calipers, underbody components, rubber bushes, and hydraulic lines. The corrosion pattern visible in the MOT data is consistent with a vehicle that has aged in service for two decades rather than one that has simply covered a high distance, as the affected areas are structural mounting points, fuel lines, and body sections that suffer from environmental exposure over time irrespective of mileage. A prospective buyer should focus the physical inspection on the rear suspension assembly, particularly the nearside shock absorber that recorded a serious fluid leak and the offside unit, which is likely of similar age and condition. On a test drive, listen for knocking or clonking from the rear over uneven surfaces, as worn shock absorbers with depleted hydraulic fluid allow the springs to oscillate excessively, and check for any rear-end instability or pitching over bumps. The rear subframe and suspension mounting brackets should be examined on a ramp or over an inspection pit for visible perforation or flaking metal, as the 2022 failure recorded the brackets as seriously weakened and the 2025 test still flagged subframe and body corrosion in the same area; serious rust at these points can compromise structural integrity and geometry, leading to vague or wandering rear-end behaviour. The fuel lines running along the underfloor should be inspected for weeping joints and surface corrosion, and any smell of petrol when the car is running or after it has been parked should be treated as immediate grounds for further investigation. The tyre and exhaust advisories from the December 2025 test also warrant direct attention before purchase. The nearside front tyre was noted as worn close to the legal limit on its edge, which on a front-wheel-drive Fiesta typically points to a wheel alignment issue, worn suspension components, or uneven camber, so a check of the tracking settings and front suspension bushes is advisable. The nearside rear tyre showed cracking and perishing, and while rubber degradation is partly age-related, it confirms the tyres will need replacement regardless of remaining tread depth. The exhaust leak from the central rear section should be audible as a ticking or hissing sound from beneath the rear of the car when the engine is running from cold, and any smell of exhaust fumes inside the cabin would indicate the leak is more substantial than the advisory suggests. Finally, the registration plate lamp failure recorded at the 2024 test is a minor electrical item, but combined with the slightly discoloured rear direction indicators it suggests the rear lamp clusters may be suffering from the typical moisture ingress and oxidisation seen on older Fiestas, and all rear lighting should be verified as fully functional before purchase.
