2004 Ford Focus 1.6L Petrol · AX04 NHZ

The most recent MOT inspection for this Ford Focus on 12 June 2026 resulted in a pass, but the vehicle's recent history indicates a worrying trend of worsening mechanical reliability and recurring emissions issues. While the vehicle has successfully passed its latest test, it follows a significant failure in June 2026 regarding exhaust emissions, specifically high carbon monoxide and lambda readings. The history shows a pattern of recurring failures related to exhaust gases and engine management, alongside persistent advisories for suspension components. This suggests that while the vehicle is currently legal, it is subject to intermittent failures that may indicate underlying engine management or exhaust system degradation. With a recorded mileage of 134,670 miles over approximately 22 years, the vehicle has averaged roughly 6,121 miles per year. This is considered low to moderate annual usage, which is typical for an older vehicle. While lower mileage generally implies less wear on the drivetrain and engine internals, it can also lead to specific issues such as rubber component perishing and corrosion due to infrequent use. In this case, the mileage is consistent with the age, but the mechanical history suggests that the components are reaching the end of their natural service life regardless of the relatively low annual distance covered. A prospective buyer must pay close attention to the suspension and exhaust systems. The MOT history shows a long-standing and recurring advisory for corrosion on all four coil springs, which has persisted since at least 2023. Corroded coil springs are prone to sudden fracture, which can cause significant damage to the suspension geometry and safety. During a test drive, listen for any metallic clunking, knocking, or creaking sounds when driving over bumps or uneven surfaces, as these are symptoms of failing springs or worn suspension bushes. Furthermore, the recent failure regarding exhaust emissions and the advisory for a minor exhaust leak suggest that the catalytic converter or oxygen sensors may be nearing failure. Watch for uneven idling, hesitation during acceleration, or a noticeable smell of exhaust fumes within the cabin. Additional inspection is required regarding the braking system and tyres. Previous advisories have noted corrosion on the nearside front brake pipe, so you should visually inspect the underside of the vehicle for any signs of fluid weeping or advanced structural corrosion near the brake lines. Given the age of the vehicle and previous advisories regarding tyre perishing and wear, check the sidewalls of all tyres for cracks or perishing, which can occur even if tread depth is sufficient. Ensure that the brake discs do not show excessive pitting and that the calipers are not binding, which can happen on vehicles that have been driven infrequently. Finally, verify that the service history is documented, as the recurring emissions issues may be linked to neglected maintenance such as spark plug changes or air filter replacements.
