2004 BMW 3 Series 3.0L Petrol · BK04 HVZ

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend in mechanical integrity and component wear. While it passed the most recent test on 10 December 2025 at 153,329 miles, this followed two failures within the same month. The transition from an excessive oil leak in November 2025 to a non-excessive leak in December suggests a repair was attempted, yet the persistent presence of multiple suspension and braking advisories indicates a vehicle that is subject to reactive rather than preventative maintenance. The mileage pattern is consistent with a low-use German vehicle of this age, averaging approximately 7,000 miles per year. However, the data shows a significant spike in activity between November 2024 and December 2025, where the car covered over 12,000 miles in just thirteen months. This rapid accumulation coincides with the cluster of mechanical failures, suggesting the vehicle has been under higher stress recently, which has exposed aging components. The gap between the 2023 and 2024 tests is standard, showing a consistent history of annual testing prior. A buyer must conduct a thorough inspection of the braking system and underbody, as corrosion in the brake pipes has been a recurring issue since 2023. The tester repeatedly flagged corroded pipes, specifically the rear pipes which were covered in grease, which often indicates an attempt to hide significant surface oxidation. Furthermore, the front suspension is showing signs of fatigue, with the offside front lower arm bush and nearside front anti-roll bar linkage both identified as worn or degrading. These issues, combined with a failing rear shock absorber, suggest the handling geometry is likely lost. The engine also requires close attention due to the reported oil leaks that reached a level sufficient for an MOT failure in November 2025. While the leak was noted as no longer excessive in the latest test, the history of excessive leaking suggests seals or gaskets are reaching the end of their functional life. The buyer should verify the structural integrity of the chassis and ensure that the corrosion noted on the brake lines has not migrated to the main mounting points.
