2008 Ford Focus 2.5L Petrol · TP06 BUD

The most recent MOT, dated 23 December 2025, resulted in a failure on the basis of an exhaust lambda sensor reading that fell outside the prescribed limits, which is recorded as a major defect. Although the test also listed a series of tyre wear advisories, the lambda failure overrides any pass status. Looking back over the past five years the pattern shows an increasing number of items moving from advisory to major status – tyre cuts in 2021, a deteriorating CV‑joint boot in 2024 and now an emissions‑system fault – suggesting that the overall maintenance trajectory is beginning to worsen rather than improve, despite the vehicle having passed several earlier tests without major failures. With 90,101 miles on the clock at 18 years old the average annual mileage works out at roughly 5,000 mi, which is well below the typical UK usage rate. Such low mileage often points to periods of light use or extended storage, both of which can be benign for wear‑related components but can also expose the car to age‑related degradation. The relatively modest mileage means that consumables such as brake pads, clutch discs and engine bearings are unlikely to be near the end of their service lives, yet the long service life raises concerns about rubber hardening, battery electrolyte loss and corrosion that develop with time rather than distance. A prospective buyer should give the tyre set a thorough visual and tactile inspection. All four tyres have repeatedly been flagged as close to the legal tread limit and the front pair previously suffered cuts that reached the ply, so confirm that the current tread depth exceeds 1.6 mm on all corners, that sidewalls are free of cracks, bulges or ageing perishing, and that the DOT code indicates the tyres are no more than six years old. While on the road, listen for any vibration or pulsation through the steering wheel that could betray uneven wear, and feel for a loose or wandering feel that might indicate worn suspension bushes or mis‑aligned steering geometry. The lambda sensor failure points to a likely fault in the oxygen sensor or associated wiring; a diagnostic scan should be performed to verify whether a sensor replacement, exhaust leak repair or ECU reset is required, and the buyer should be prepared for a possible emissions‑related repair costing a few hundred pounds. Given the vehicle’s age and low‑usage profile, the buyer should also check items that deteriorate with time. Inspect the inner CV‑joint boot on the nearside front axle for cracks or grease loss, as a failing boot can quickly lead to joint failure. Examine the brake discs for scoring, pitting or excessive thinning, and test for any pedal pulsation or shudder under braking. Verify the condition of the battery, preferably with a load test, and look for signs of corrosion on terminals. Finally, confirm that the engine oil, brake fluid and coolant have been changed within the recommended intervals – fluids can absorb moisture and lose effectiveness even on low‑mileage cars – and inspect the under‑carriage for any rust or corrosion that may have developed during periods of standing. Addressing these points will give a clear picture of the car’s current roadworthiness and any imminent maintenance that may be required.
