2009 Ford Focus 1.6L Diesel · RF58 COU

The most recent MOT test on the 2009 Ford Focus recorded a failure in September 2023, with multiple major defects including a persistent engine malfunction indicated by the Malfunction Indicator Lamp (MIL), which suggests an unresolved catalytic converter or oxygen sensor issue that could lead to further emissions-related problems if not addressed. This follows a pattern of recurring MOT failures over the past five years, particularly in the areas of suspension components, exhaust integrity, and safety-related items such as the offside front seatbelt webbing, which was deemed dangerously weakened. While earlier MOTs in 2022 and 2021 were clean apart from minor advisories—such as worn suspension bushes and a deteriorated CV joint boot—these advisories have since escalated into major defects, indicating a lack of timely maintenance or potential neglect of routine servicing. The vehicle’s history thus reflects a concerning trend of deferred repairs, with the most critical issues now surfacing during testing, warranting immediate attention to prevent further roadworthiness compromises. The recorded mileage of 159,604 miles for a 17-year-old Ford Focus represents a moderate annual usage rate of approximately 9,388 miles per year, which is within the expected range for a vehicle of this age and class. However, the consistency of mileage accumulation—particularly the absence of significant gaps between MOT tests—suggests either sustained, heavy usage or a pattern of prolonged inactivity followed by rapid mileage accumulation, which could exacerbate wear on critical components. Heavy annual mileage accelerates the degradation of suspension elements, brakes, and drivetrain components, while prolonged idling or standing increases the risk of corrosion, particularly in the exhaust system, brake components, and electrical connections. The presence of multiple advisories related to suspension arm bushings and wheel bearings, coupled with the CV joint boot failure, underscores the need for a thorough inspection of the entire suspension geometry, as excessive wear in these areas can lead to steering instability, uneven tyre wear, or even wheel detachment if left unaddressed. To proceed with a purchase, the prospective buyer should conduct a meticulous physical inspection and road test to verify the presence and severity of the recorded defects, particularly the engine MIL and seatbelt webbing failure, which are critical to roadworthiness. During the inspection, focus on the exhaust system for signs of rust propagation, particularly around the rear silencer and heat shields, as corrosion can compromise structural integrity and lead to leaks or emissions violations. Listen for unusual noises during the test drive, such as clunks from the suspension (indicating worn or broken suspension arms or ball joints), grinding from wheel bearings, or a rough idle or hesitation from the engine (suggesting the MIL issue may be persistent). Additionally, check the brake system for signs of binding calipers, warped discs, or uneven wear, as the nearside rear tyre advisory from 2018 hints at potential brake-related issues. The offside front seatbelt webbing failure is particularly alarming, as it may have been overlooked during previous tests, so ensure the webbing is fully functional and not frayed or stretched. If the engine MIL persists, a diagnostic scan should be performed to pinpoint the exact fault code, as catalytic converter or sensor failures can lead to costly repairs if not addressed promptly. For a vehicle of this age and mileage, the buyer should also prioritise checks on consumables and long-term wear items that may not have been flagged in MOTs due to their non-obvious nature. Inspect the tyres for sidewall cracking or perishing, which can occur even at moderate mileages due to age-related degradation, and verify that the tread depth remains above the legal minimum. Check the 12V battery for signs of corrosion on terminals, a weak or slow crank, or excessive discharge when the engine is off, as older vehicles are more susceptible to battery failure. Fluid levels should be topped up to manufacturer specifications, with particular attention given to brake fluid, which can absorb moisture and degrade over time, leading to brake shudder or spongy pedal feel. Finally, review the service history for any missing or delayed maintenance, such as oil changes, timing belt replacement, or suspension component servicing, as these can significantly impact the vehicle’s reliability. If the buyer is concerned about the engine MIL or exhaust corrosion, they may also consider a pre-purchase inspection by a qualified mechanic to assess the extent of the underlying issues before finalising the purchase.
