2009 BMW 525 3.0L Diesel · RE59 LTO

The vehicle’s most recent MOT test on 2022-11-05 confirms it remains roadworthy, though the record reveals an unusual retest just three days prior on 2021-10-15, which failed without any defects logged—a rare anomaly that suggests either a clerical error or a test centre oversight. Since then, the car has passed two consecutive tests without failings, indicating no recurring mechanical issues were detected by the tester. However, the absence of defects in any of these tests does not preclude hidden wear, particularly on high-mileage components like suspension bushes, coil springs, or drivetrain joints, which often fail silently before becoming MOT-critical. The recorded mileage of 242,070 miles over 17 years equates to an average of approximately 14,200 miles annually, which is elevated for a vehicle of this age. The gap between the 2021 and 2022 tests—roughly 15,000 miles in a year—suggests consistent use rather than prolonged storage, though the retest in October 2021 implies either a rushed inspection or a brief period of non-use before the car was brought back into service. The lack of intermediate MOTs or service records means there is no evidence of preventive maintenance, such as regular suspension or brake servicing, which could have mitigated accelerated wear. Given the high mileage and the absence of documented faults, a buyer should prioritise an independent inspection of the suspension system, particularly the rear axle where binding calipers or worn bushes are common in this model. The brakes, including discs and pads, should be checked for uneven wear or corrosion, as should the drivetrain for signs of fluid leaks or excessive play in joints. Structural corrosion, particularly around wheel arches and sills, is another critical area to examine, given the vehicle’s age and exposure history. The engine bay should also be scrutinised for oil leaks or degraded hoses, as these are often overlooked until they become serious. While the MOT history is clean, the lack of maintenance documentation raises concerns about long-term reliability.
