2003 BMW X5 2.9L Diesel · PX53 AAZ

The vehicle is currently roadworthy following a pass in February 2026, but the maintenance trend shows a shift toward developing mechanical wear. The most recent test at 87,894 miles identified wear on both the offside and nearside front drive shaft joints. While these did not cause a failure, they represent a progression from the severely deteriorated constant velocity boot noted in February 2025, indicating that the front drivetrain components are now reaching the end of their operational life. The mileage data presents a significant discrepancy that requires careful scrutiny. Between January 2023 and February 2024, the vehicle covered 22,345 miles, jumping from 119,276 to 121,621 miles. However, the February 2026 record shows only 87,894 miles, an impossible drop of over 33,000 miles from the previous entry. This suggests either an odometer error or that the vehicle sat stationary for long periods, which often leads to degradation of rubber components and fluid seals despite the low annual mileage. A buyer must prioritise a thorough inspection of the underbody due to the tester flagging corrosion in the suspension and underbody during the February 2026 test. Given the age of the vehicle, structural integrity should be verified for deep-seated rust rather beyond surface scaling. The front drive shaft boots should be checked for grease leakage, as the recorded wear on the joints suggests imminent failure. Additionally, the history of perishing tyres in 2024 suggests that rubber components may be suffering from age-related cracking regardless of remaining tread depth.
