2012 Ford Focus 1.6L Diesel · FT12 AAK

The most recent MOT on 22 December 2025 was a pass, but it was accompanied by a number of advisories covering tyre tread, front brake pad wear, rear brake‑hose deterioration and reduced damping on the off‑side rear shock absorber. The preceding test on 18 December 2025 failed because the supplementary restraint system warning lamp remained illuminated, and it also highlighted corroded brake pipes and thin front brake pads. Earlier in 2024 the vehicle both passed and failed the same day, the failure again being the SRS warning lamp, while the pass recorded sub‑frame corrosion, pitted front brake discs and an oil leak. The pattern shows a maintenance trajectory that is deteriorating rather than stabilising, with several safety‑critical items – the air‑bag system, brake pipe integrity and suspension damping – recurring without clear evidence of remedial work. At 123 659 miles the Focus has averaged roughly 8 800 miles per year over its fourteen‑year life, which sits comfortably within normal UK usage for a family hatchback. There are no obvious mileage gaps that would suggest long periods of storage, yet the relatively modest annual distance means that wear on consumables will be more a function of age than of high‑mileage fatigue. Consequently, components that degrade with time – rubber hoses, brake linings, tyre compounds and corrosion‑prone bodywork – are likely to be approaching the end of their service life despite the moderate mileage figure. A prospective buyer should give the SRS system immediate attention; verify that the air‑bag warning lamp extinguishes after the ignition is switched on, and arrange a qualified diagnostic scan to confirm that the control module and sensors are fault‑free. Inspect all brake‑pipe and hose fittings for rust, pitting or greased deposits, especially around the nearside rear and both front pipes, and feel for any soft or spongy pedal response that could indicate fluid leakage or hose deterioration. Examine the front brake discs for deep scoring or excessive thickness variation, and measure the remaining pad material – thin pads can lead to brake fade and increased disc wear. The rear shock absorber on the off‑side should be bounced to detect any loss of rebound resistance, and a test‑drive should reveal any clunking or uneven rear‑wheel movement that would suggest deteriorated damping. Tyres should be checked for tread depth on all four corners, paying particular attention to the inner edges that were flagged as close to the legal limit; uneven wear may point to mis‑aligned suspension or worn camber/caster bushes. Because the vehicle is over a decade old, time‑related degradation must also be addressed. The recorded oil leak, although not excessive, warrants a visual inspection of the valve cover gasket and oil filter housing for fresh oil traces, and a leak‑free engine oil change with a fresh filter is advisable. The sub‑frame corrosion noted in 2024 should be probed for any signs of rust spreading into mounting points; any structural weakening would manifest as a rattling noise when accelerating or braking. Verify that the under‑tray is securely fitted and not trapping moisture against the chassis. Finally, test the 12 V battery voltage and load, replace the battery if it is more than three years old, and ensure that all fluids – brake, coolant, power‑steering and gearbox – have been refreshed within the manufacturer’s service intervals, as calendar ageing can cause fluid breakdown even on relatively low‑mileage cars.
