2017 BMW 335 3.0L Diesel · YA17 AAF

The most recent MOT test result for the 2017 BMW 335 indicates a clean pass on 2025-10-24, following a previous failure in 2024-10-26 where two dangerous defects were recorded concerning exposed tyre cords on both rear tyres. This marks a significant improvement in roadworthiness, as the vehicle previously failed due to critical tyre integrity issues, which can compromise braking performance and structural integrity under high loads. The intervening clean MOT results from 2023 and 2022 suggest a stable maintenance trend, though the 2024 failure highlights a need for careful attention to tyre wear patterns and potential underlying causes, such as misalignment, excessive speeding, or improper inflation. The absence of further defects since the 2024 failure is encouraging, but prospective buyers should remain vigilant about tyre condition and address any lingering concerns promptly to prevent recurrence. The vehicle’s recorded mileage of 87,598 miles over approximately nine years represents an average annual usage of around 9,733 miles, which is within the expected range for a BMW of this age and class. While lower mileage might suggest periods of reduced use or storage, the consistent annual accumulation indicates moderate to heavy usage, particularly in the later years where wear on consumables, suspension components, and drivetrain elements is more pronounced. The absence of significant mileage gaps does not necessarily indicate poor maintenance, but it does imply that the vehicle has been driven regularly, which can accelerate wear on critical systems such as brakes, tyres, and exhaust components. Buyers should note that higher mileage increases the likelihood of pre-existing wear, particularly in areas like brake discs, suspension bushes, and internal tyre tread wear, warranting thorough inspection. Given the recent MOT history, the most critical immediate concern is the exposed tyre cords from the 2024 failure, which necessitate urgent replacement of the rear tyres. Prospective buyers should inspect the remaining tyres for further signs of cord exposure, uneven wear, or tread depth below the legal minimum of 1.6mm, as this can lead to poor traction, hydroplaning risks, or sudden failure. During a test drive, listen for unusual noises from the rear tyres, such as a grinding or squealing sound that may indicate internal cord fraying. Additionally, check for excessive play in the steering or uneven suspension movement, which could suggest misalignment or worn suspension components contributing to uneven tyre wear. The buyer should also verify that the tyres were replaced with appropriate load and speed ratings for the BMW 335, as incorrect tyres can exacerbate handling issues. For the broader assessment, the vehicle’s clean MOT history since 2023 suggests that the previous tyre defects have been resolved, but buyers should conduct a comprehensive physical inspection. Focus on the suspension system for signs of worn suspension bushes, coil spring degradation, or binding calipers, as these can lead to clunking noises or reduced ride quality. Inspect the brake system for corrosion on discs, warping, or uneven thickness, and check for brake fluid leaks or sponginess in the pedal feel, which may indicate hydraulic issues. The 12V battery should be tested for voltage output under load, as BMWs of this age can suffer from battery degradation, particularly if the vehicle has been stored for extended periods. Finally, given the vehicle’s age and mileage, consider the calendar-based servicing of fluids such as coolant, transmission fluid, and differential oil, as these degrade over time regardless of mileage. A thorough check of the exhaust system for corrosion, leaks, or reduced emissions output is also advisable, as BMWs of this era may require periodic catalytic converter inspection or replacement to meet modern emissions standards.
