Servicing follows BMW Condition Based Servicing. The system tracks oil condition, brakes and filters and signals when due, commonly oil changes around 15,000–30,000 km or two years. Brake fluid is typically every two years. Keep full service history for longevity of the B48 engine and ZF gearbox.
Safety rating is five stars from Euro NCAP (2017 data applied to the X4 via shared X3 platform, with extra side tests confirming results): 93% adult, 84% child, 70% pedestrian, 58% safety assist. Standard kit includes multiple airbags, full DSC suite networked with xDrive, Hill Descent Control, Performance Control, attention assistant and city collision warning with braking. Optional packs add lane keeping, adaptive cruise and more.
To keep the car, stick to CBS intervals, use approved oils and monitor tyres and brakes. The run-flat tyres and solid structure support everyday reliability when maintained properly. Optional Active Protection closes windows and roof and tightens belts if a crash is likely.
