2005 Ford Mondeo 1.8L Petrol · SH05 AEL

Corrosion is the defining mechanical story of this 2005 Ford Mondeo. Both the front and rear subframes have been flagged as corroded but not seriously weakened at every recorded test since 2019, and the rear subframe also carried a worn pin or bush advisory in 2020. The latest recorded test on 7 September 2021 ended in a pass, but only after a same-day failure for a windscreen obstruction in the driver's swept view, which was clearly rectified and retested. That pass still carried five advisories, including the recurring subframe corrosion, worn and pitted front brake discs, a noisy rear exhaust, and a fluctuating offside rear service brake. Taken as a whole, the trend from 2017's clean pass to the present is one of gradual deterioration concentrated in the underside structure and braking system, with two earlier failures also on record: a rough offside rear wheel bearing in April 2018 and an unspecified failure in August 2019, both followed by passes within days. The recorded mileage of 103,955 miles over roughly 21 years equates to around 4,950 miles per year, which is low for a car of this age. The test dates themselves reveal an unusual pattern: annual tests shifted from April in 2017 and 2018 to August in 2019 and 2020, then September in 2021, and there is no recorded test after September 2021, leaving a gap of around five years to the present date. That gap is significant. A car that has potentially stood unused or untested for an extended period is precisely the environment in which the already-noted subframe corrosion, brake pipe corrosion, and brake hose deterioration can advance unchecked, and the advisories recorded in 2021 may understate the current condition. A prospective buyer should treat the subframes as the priority inspection item. The front and rear subframes were described as corroded but not seriously weakened, but that assessment is now five years old. The car should be raised on a lift so the subframes, mounting points, and surrounding floorpan can be examined for perforation, flaking metal, or weakening around suspension attachment points. The rear subframe bush noted as worn in 2020 should be checked for excessive movement, and on a test drive any clunking or knocking from the rear over bumps, or a vague, wandering feel from the back axle, would suggest that wear has progressed. The braking system also warrants close scrutiny. The nearside front brake pipe has been flagged for corrosion in 2018 and 2019, the rear brake hose ferrule showed corrosion in 2020, and the nearside front brake hose was deteriorating at its body fixing. The front discs were recorded as worn, pitted, or scored in 2021, and the offside rear brake was fluctuating. On a test drive, feel for judder or pulsing through the pedal under braking, any pull to one side, and uneven braking effort, then inspect the pipes and hoses along their full length for heavy rust or weeping. The noisy rear exhaust advisory should be checked for blowing, rattles, or corrosion at the joints, and given the 2018 rear wheel bearing failure, listen for any humming or droning that rises with road speed. Finally, given the five-year absence from the testing system, a fresh MOT and an independent inspection before purchase would be prudent.
