2010 Ford Focus 1.6L Petrol · WN10 PVL

The most recent MOT on 16 March 2026 recorded a failure. The test flagged an inoperative engine malfunction‑indicator lamp and an obvious mis‑aim of the nearside headlamp, both of which are mandatory safety items. In addition, the same inspection reiterated the advisory about slight play in the rear anti‑roll‑bar linkage ball joint and progressive rust on rear suspension components, issues that have been recurring for several years. Compared with the previous three years, which were all passed albeit with advisory notes on suspension wear and rust, the move from advisory to outright failure indicates a deterioration in the vehicle’s condition and suggests that underlying faults are now reaching the point of non‑compliance. At 113,324 miles the Focus averages just over 7,000 miles per annum, a figure that sits comfortably within the typical UK usage pattern for a sixteen‑year‑old car. The mileage does not suggest any periods of extreme short‑term abuse, but the relatively modest annual distance also implies that the vehicle may have spent considerable time stationary. Prolonged standing can accelerate corrosion of suspension and exhaust mounting points, and can allow brake discs to develop surface rust that may affect braking performance when the car is first driven after a long lay‑up. For a prospective buyer the immediate priority is to have the engine management fault diagnosed on a proper scan tool. An inactive MIL can be caused by a faulty oxygen sensor, a loose electrical connection, or a more serious ECU issue; any related fault codes should be cleared and the system re‑checked to ensure the lamp illuminates correctly. The headlamp aim must be adjusted to meet legal illumination angles, and the driver should verify that the beam is correctly centred and does not dazzle oncoming traffic. On a test drive, listen for clunking or excessive play when the rear anti‑roll bar is loaded, especially over bumps or during cornering, as the advisory‑noted ball‑joint play can compromise handling stability. Inspect the rear suspension for surface rust that may be progressing into structural members, and examine the rear exhaust bracket for cracks or corrosion that could lead to exhaust leaks or rattles under acceleration. Given the age and mileage, a thorough visual and tactile inspection is advisable regardless of the MOT findings. Check all four tyres for sidewall cracking, dry rot or uneven tread wear that might indicate mis‑alignment or worn suspension bushes. Examine the battery terminals for corrosion and assess the battery’s cranking performance, as a twelve‑volt unit of this vintage may be nearing the end of its service life. Verify that brake discs are not excessively scored or heavily rusted, and that calipers move freely without binding. Finally, confirm that all fluid levels—engine oil, coolant, brake fluid and power‑steering fluid—have been changed within the recommended service intervals, as time‑based degradation can occur even on low‑use vehicles. Addressing these points will give a clear picture of any imminent maintenance costs and the overall roadworthiness of the 2010 Focus.
