2017 BMW 5 Series 3.0L Diesel · CV17 MKJ

Recurring issues with the offside front drive shaft constant velocity boots represent the most significant mechanical trend in this vehicle's recent history. Following a dangerous failure in March 2021 due to a cracked offside rear road wheel, the record shows a period of clean tests before a major failure in October 2024 regarding a split outer CV boot. This specific defect persisted as a minor advisory for the offside front drive shaft joint constant velocity boot, which was still noted as severely deteriorated during the most recent pass on 14 October 2025. The vehicle has covered 109,964 miles over approximately nine years, averaging roughly 12,218 miles per year. This level of annual accumulation is higher than the UK average for a vehicle of this age, suggesting consistent long-distance or high-frequency usage. Mechanically, this higher mileage profile typically correlates with increased wear on consumable components such as suspension bushes, braking systems, and drivetrain elements, which aligns with the recent deterioration observed in the drive shaft components. A prospective buyer should pay close attention to the drivetrain during a test drive, specifically looking for any rhythmic clicking or popping noises when turning the steering wheel at low speeds, which can indicate that the CV joints are failing following the deterioration of the protective boots. Additionally, because the offside rear wheel was previously flagged with a dangerous welding defect, a physical inspection of the wheel rim for any signs of structural cracks, repairs, or significant impact damage is essential to ensure the integrity of the wheel has been fully restored. Given the recent history of CV boot deterioration, it is also prudent to check for any vibrations through the steering wheel or floorpan during acceleration, which could signal internal damage to the drive shaft joints. While the recent pass indicates the vehicle met minimum standards, the recurring nature of the boot deterioration suggests that the rubber components are reaching the end of their service life and should be monitored for further splitting or grease leakage.
