2004 BMW 3 Series 3.0L Petrol · WN04 DZW

The vehicle presents a concerning roadworthiness status, as the maintenance history indicates a period of mechanical neglect followed by reactive repairs. The most recent test in December 2021 at 139,791 miles shows a pass only after a significant failure six days prior. That failure highlighted a continuous engine oil leak and a misfiring engine, alongside pitted brake discs. While the vehicle passed the subsequent test, the absence of any MOT records for the following five years leaves the current state of these critical mechanical systems unknown and potentially degraded. The mileage pattern remains consistent with a low-use vehicle of its age, averaging approximately 6,350 miles per year. Between November 2018 and December 2021, the car covered roughly 17,000 miles, suggesting a steady but modest usage rate during that three-year window. While the low mileage generally reduces wear on the drivetrain components, the lack of recorded data since late 2021 suggests the car has either sat stationary for long periods or operated without legal testing. Long standing periods often lead to the degradation of rubber seals and fluid-related corrosion which mileage alone does not reflect. A buyer must conduct a thorough physical inspection of the engine bay to verify if the continuous oil leak reported in December 2021 was actually rectified. The previous misfire issue also suggests potential faults with ignition components or fuel delivery that require diagnostic attention. Given the history of pitted brake discs and a rear differential fluid leak, the entire braking system and drivetrain should be checked for binding calipers and weeping seals. Furthermore, with a vehicle this age, a close inspection of structural integrity regarding the wheel arches and underbody corrosion is essential, as previous records already noted damaged liners which often mask emerging rust.
