2005 Ford Focus 1.6L Petrol · FV05 AEN

A recurring pattern of structural corrosion around the rear suspension mounting points sits at the heart of this Ford Focus's MOT history. The 2021 test produced a fail on 18 October with major defects flagged at both the nearside and offside rear outer sills, where the suspension component mounting prescribed areas were recorded as excessively corroded to the extent that structural strength was significantly reduced, alongside a major defect on the offside track rod end ball joint for excessive play. The vehicle was retested on 20 October and passed, but the underlying sill corrosion would not have been rectified in that two-day window, meaning the structural integrity concern remains. Earlier records reinforce the corrosion theme: 2019 saw advisories on all four outer brake pipes for corrosion, including one test that also failed on the offside rear parking brake being inoperative on one side. The 2018 tests, both a fail and subsequent pass on the same day, recorded slight corrosion across all four outer brake pipes and a minor exhaust flexi leak. Two passes in 2017 and 2020 carried no advisories, but the chronological drift shows a worsening picture from minor brake pipe surface corrosion in 2018 through to major structural corrosion at the rear suspension mountings by 2021. The recorded mileage of 104,469 over approximately 21 years equates to an annual accumulation of around 4,975 miles, which is low for the vehicle's age and suggests either light regular use or extended periods of limited driving. The MOT testing record contains a notable gap between 2020 and 2021, with no test recorded for the intervening twelve months, and another shorter gap between 2019 and 2020. Low annual mileage combined with gaps in testing can mean that some components sit dormant for prolonged intervals, allowing brake pipe corrosion to advance unseen, rubber bushes to stiffen, and exposed underbody metalwork to oxidise without regular road exposure to clear surface moisture. The annual accumulation rate between tests is not consistently verifiable from the records provided, but the pattern of worsening corrosion defects is consistent with a vehicle that has either been used predominantly for short trips, or stored for periods, neither of which is favourable for preserving bodywork and undercarriage components on a 21-year-old vehicle. Any prospective buyer should treat the rear outer sill and rear suspension mounting areas as the primary inspection priority. The outer sills on the Focus of this generation are load-bearing structures, and corrosion in the suspension prescribed area can compromise mounting points for the rear beam, trailing arms, or coil spring seats. On a physical inspection, look for bubbling, lifting, or perforation along the lower sill seams, paying particular attention to where the sill meets the rear wheel arch and the jacking point area. Place a hand on the rear of the car and push down firmly to check for any knocking or excessive vertical movement that could indicate compromised rear suspension geometry. Check that the rear beam mounting bolts and any visible bushes appear intact, and look for signs of recent welding, underseal patching, or filler, which would suggest prior repair rather than original structure. The track rod end defect from 2021 is another area to verify, as a worn ball joint can produce vague steering, a knocking through the steering wheel on full lock, or uneven tyre wear, particularly on the inside or outside shoulder of the front tyres. During a test drive, listen for any clonking from the front end over speed humps and verify that the steering returns to centre smoothly without drift. The recurring brake pipe corrosion advisories across all four corners warrant careful attention, even though these were advisories rather than failures. On inspection, examine the brake pipes along their full length, particularly where they run along the underbody and behind the wheels, looking for rust bloom, pitting, or any sign of previous repairs with copper or steel unions. A firm push on the brake pedal should produce a solid feel without sponginess, and the handbrake should hold the vehicle on an incline without the offside rear cable slipping. Finally, request that the rear flexi section of the exhaust is checked for blowing, as the 2018 advisory noted a minor leak there, and verify no warning lights are present on the dashboard given the vehicle's age and intermittent use pattern.
