2020 BMW 6 Series 2.0L Diesel · MA20 AET

The vehicle's most recent MOT history shows a concerning recurring fault regarding the engine management system. While the car passed its test on 1 June 2026 at 29,199 miles, the tester first flagged an inoperative or malfunctioning Malfunction Indicator Lamp (MIL) during that same session. This specific failure (8.2.2.2 (g)) also caused a failure during the 3 June 2025 test at 26,197 miles. This pattern suggests an intermittent electronic fault or a sensor issue that has persisted for two consecutive years, indicating that while the vehicle is technically roadworthy now, the underlying cause of the MIL fault may not have been comprehensively resolved. The mileage accumulation is notably low for a 2020 model, averaging roughly 4,866 miles per year. The data shows steady, incremental growth from 16,946 miles in June 2023 to 29,199 miles in June 2026. This low-use pattern often implies lighter mechanical wear on the drivetrain and suspension components, but it can also lead to issues such as battery degradation or seized components from long periods of inactivity. The consistency in the mileage increments suggests regular, albeit infrequent, usage rather than erratic or heavy-duty driving. A prospective buyer must prioritise a diagnostic scan to identify the root cause of the repeated MIL failures. Because the engine management light has been flagged twice, a simple reset may not suffice, and the fault could relate to emissions sensors, ignition components, or the ECU itself. Beyond the electronic issues, the June 2023 test at 16,946 miles noted both nearside and offside rear tyres worn close to the legal limit. While this appears to be standard consumable wear, the buyer should inspect the current tyre tread depth and check for uneven wear patterns that might indicate alignment issues or worn suspension bushes.
