2017 BMW 335 3.0L Diesel · YF17 AAX

The vehicle currently holds a roadworthy status but the records reveal a trend of worsening mechanical wear and reactive maintenance. While it passed its most recent test in October 2025 at 115,416 miles, this followed a failure just four days prior. That failure highlighted a major exhaust leak and multiple structural tyre failures, including bulges and lumps. The presence of worn steering rack inner joints is a persistent issue dating back to 2024, suggesting a component that is being intermittently addressed rather than proactively replaced. The mileage profile indicates high usage for a nine-year-old vehicle, averaging approximately 12,800 miles per year. There is a significant jump in usage between August 2022 at 63,694 miles and September 2024 at 100,222 miles, representing over 36,000 miles driven in two years. This accelerated rate of travel correlates with the appearance of heavy-duty faults, such as the serious fluid leak in the offside front shock absorber in 2024 and the recurring tyre issues noted in the latest tests. A buyer must conduct a thorough underbody inspection of the steering and suspension, as the steering rack inner joints have flagged for play across multiple years. The exhaust system repair in late 2025 needs verification to ensure the major leak was fully rectified. Furthermore, the transmission box oil leak recorded in 2024 should be monitored to ensure the rate has not increased. Given the history of inner-edge tyre wear, a professional wheel alignment check is essential to prevent further premature degradation of expensive tyres.
