2020 BMW 118 1.5L Petrol · AF70 LXM

The most recent MOT test recorded on 2025-10-06 resulted in a failure due to an active engine malfunction indicated by the Malfunction Indicator Lamp (MIL), alongside a persistent advisory regarding offside rear tyre wear nearing the legal limit with edge wear. This failure contrasts sharply with the two previous MOTs, which were clean, indicating a concerning deterioration in the vehicle’s engine management system over the past year. The pattern suggests either a developing fault in the engine control unit (ECU), sensor degradation, or a more serious underlying issue such as a failing fuel injection system, ignition coil, or oxygen sensor. The advisory on tyre wear, while not failing the vehicle, is critical as edge wear typically signals improper alignment or suspension issues that, if ignored, could lead to premature tyre failure or handling problems. The recorded mileage of 89,656 miles for a 2020 BMW 118i represents a high annual usage rate of approximately 14,943 miles per year, which is notably elevated for its age. Such mileage accumulation over six years implies significant exposure to wear and tear on consumables like brake pads, suspension components, and drivetrain elements, particularly if the vehicle has been driven in varied or aggressive conditions. The absence of substantial service intervals or long periods of inactivity could also accelerate fluid degradation, such as in the engine oil, brake fluid, and differential fluid, which may require replacement sooner than recommended. Additionally, the rapid mileage increase may indicate either heavy use or a history of frequent short journeys, both of which can exacerbate issues like condensation in the fuel system or accelerated tyre wear patterns. Given the recent MOT failure and the recurring tyre advisory, the prospective buyer should prioritise a thorough inspection of the engine bay for signs of oil leaks, particularly around the valve cover, oil pan, and oil filter housing. Listen for unusual engine noises, such as knocking, ticking, or misfires, which could indicate failing components like camshaft seals, valve train issues, or a failing turbocharger. The offside rear tyre edge wear suggests potential misalignment, so check for uneven suspension travel, binding in the rear suspension bushes or coil springs, or worn suspension arms. During a test drive, monitor for handling anomalies, such as pulling to one side or excessive vibration, which may reveal deeper suspension or steering system wear. Immediate attention to the engine issue is essential, as unresolved faults can lead to further damage, reduced fuel efficiency, or even catastrophic failure. For the buyer, the next steps should include a comprehensive mechanical inspection by a qualified BMW specialist, focusing on the engine control system, fuel delivery, and ignition components. Additionally, the tyre wear pattern warrants a check of the vehicle’s alignment and suspension geometry, with any necessary adjustments or component replacements addressed promptly. Beyond the immediate concerns, the buyer should also consider a full fluid flush, including engine oil, brake fluid, and differential fluid, given the high mileage and potential for fluid degradation over time. In the interim, the buyer should avoid driving the vehicle if the MIL remains illuminated, as this could lead to further engine stress or potential emissions violations. If the tyre wear is confirmed to be due to alignment issues, corrective action should be taken to prevent further uneven tyre wear and potential handling instability.
