2004 BMW 645 4.4L Petrol · LC04 YMW

The vehicle maintains a roadworthy status, though the records reveal a persistent trend of age-related rubber component degradation. The most recent test in July 2023 at 93,780 miles flagged a central front lower oil leak and worn bushes on both front suspension arms. While these issues were not enough to result in a failure, the recurring nature of suspension wear across the last decade indicates that the components are reaching the end of their functional life despite the low annual mileage. The mileage pattern is exceptionally low for a 22-year-old vehicle, averaging approximately 4,263 miles per year. There is a significant gap in data between 2009 and 2013, during which the car covered only 3,769 miles over four years. This low usage suggests the vehicle sat for long periods, which often leads to the premature drying of rubber seals and the deterioration of bushings, as evidenced by the deteriorating rear suspension arm mountings noted in 2018 and 2020. A buyer must focus their inspection on the front suspension assembly, as the tester has repeatedly identified worn bushes and track rod ends in 2018, 2020, and 2023. The reported front lower oil leak requires a physical verification to determine if it is a minor seepage or a more significant gasket seal failure. Additionally, the 2020 failure regarding the supplementary restraint system warning lamp necessitates a diagnostic check of the airbag system to ensure the fault was properly rectified, as it does not appear in subsequent tests.
